Why this report stops at Kindergarten. AcornSmarts serves Pre-K through Grade 5: 17 of its 81 skills are flagged for the Pre-K track — Counting, Compare Numbers, Shapes, Sort & Size, Patterns, Sight Words, Letters, Phonics, Sílabas, Read It Myself, Tracing, First Letter, Animals & Nature, Community Helpers, Feelings, Colors, Weather. These are leveled skills, so several also carry claims at higher grades in the tables below. This crosswalk maps only to Kansas's K–5 academic standards documents, which begin at Kindergarten — and 14 of those 17 Pre-K-flagged skills are claimed here against a Kindergarten or later code; the 3 claimed against nothing (Sílabas, Feelings, Colors) are listed in the not-counted section below. Kansas does separately publish early-learning standards for the years before Kindergarten — the Kansas Early Learning Standards (KELS, KSDE) — and we have NOT crosswalked against them; no Pre-K alignment is claimed here.

AcornSmarts is a question-based practice app. In ELA it practices what short, checkable questions can honestly practice: phonics and word analysis, spelling, vocabulary and word relationships, grammar and mechanics recognition, and comprehension of short passages. Whole categories of the Kansas ELA standards require things a practice app does not do, and we do not claim them:
The counts above account for 101 of the 110 not-covered ELA standards (the remaining 9: W.K.11, W.1.11, RF.2.4, RF.3.4, W.3.12, RF.4.3, W.4.12, RF.5.3, W.5.12). This boundary is deliberate: we would rather report an honest PARTIAL/NOT-COVERED map than claim standards a teacher would not agree we practice.

Kansas adopted the Next Generation Science Standards unchanged in June 2013 (there are no Kansas-specific science codes). Every NGSS standard is a performance expectation: a science and engineering practice, applied to a disciplinary core idea (DCI), through a crosscutting concept. The verbs are the standard — plan and conduct an investigation, develop a model, construct an argument with evidence, obtain and combine information.
A question bank cannot conduct a hands-on investigation. Most of our evidenced science mappings are therefore PARTIAL — the DCI knowledge a child still has to know while they investigate. The 12 rows marked FULL earned it a different way: build-item interactions added in 2026 have the child perform the representable practices on screen — placing each kind of land and water to build a model of a landscape, building the rows of a data display one mark at a time. Where the standard's verb is represent or use a model and the item makes the child do exactly that, FULL is the honest verdict — and every such row carries a live item you can play right here. Any vendor claiming blanket FULL NGSS coverage from multiple-choice items is still claiming practices they did not build.
Those four buckets are mutually exclusive and account for all 4 not-covered performance expectations.
Where we DO support a PE, the support is real: the DCI content is asked directly, with a written explanation on every item. Use AcornSmarts as the knowledge-and-vocabulary layer underneath an NGSS unit — the thing children still have to know while they investigate — never as the unit itself.

Grade 1: 1-PS4-3, 1-PS4-4
Grade 3: 3-LS2-1
Grade 4: 4-PS3-4
The 2020 Kansas HGSS standards are five big ideas, each with four benchmarks, and they apply at every grade K–12 — there are no grade-level topic codes to crosswalk against. The document is explicit that it “encourages the focus on discipline-specific application of content in authentic situations rather than specific content.” Each grade carries a focus standard: K = Std 1 (Sense of Self), 1 = Std 2 (Families), 2 = Std 4 (Then and Now), 3 = Std 3 (Communities), 4 = Std 5 (Kansas and US regions), 5 = US History to 1800.
The four benchmarks escalate: x.1 recognize and evaluate → x.2 analyze context and draw conclusions → x.3 investigate and connect to contemporary issues → x.4 make a claim or advance a thesis using evidence and argument. The 5 x.1 and 5 x.2 benchmarks are the reachable ones, and we claim them PARTIAL — our items recognize and, at the x.2 tier, connect context and draw simple conclusions; they do not evaluate sources or investigate.
Honest posture for a curriculum director: AcornSmarts supplies the background knowledge and vocabulary (civic roles, rights and responsibilities, economic choice, geography, national symbols, chronological order) that Kansas students bring into HGSS inquiry.

Order & Position — VERIFIED UNMAPPED: the 2017 Kansas K-5 math standards contain no ordinal-position standard (ordinality appears only in the glossary). Kept as a readiness skill; not counted toward standards coverage.
Chance & Probability — VERIFIED UNMAPPED: Kansas K-5 math has no probability standards — statistics & probability begin at Grade 6 (6.SP). Kept as enrichment; not counted toward K-5 coverage.
Ratios & Rates — BEYOND K-5: ratios & rates are Grade 6 in Kansas (6.RP.1-3). Offered as a Grade-6 preview for advanced 5th graders; excluded from K-5 coverage claims.
Percents — BEYOND K-5: percents are Grade 6 in Kansas (6.RP.3). Offered as a Grade-6 preview; excluded from K-5 coverage claims.
Sílabas — SUPPLEMENTAL: Spanish-native foundational literacy (sílabas). The Kansas ELA standards are English-language standards; this skill supports biliteracy and RF.K.2-style phonological awareness concepts but is not counted toward KS ELA coverage.
Colors — NOT counted toward NGSS coverage. Color naming is pre-K readiness vocabulary; no K-5 NGSS performance expectation covers it (1-PS4-2 is about illumination and being seen, not color words). Previously carried a vague 'NGSS Physical Science (readiness)' domain label — removed 01AUG2026 as an unevidenced claim.
States & Capitals — NOT counted toward HGSS coverage. Place-name recall is not an HGSS benchmark: the 2020 standards deliberately specify thinking skills rather than a content list ('the focus on discipline-specific application of content in authentic situations rather than specific content'). Kept as geography readiness, claimed as nothing.
Feelings — NOT counted toward HGSS coverage. Social-emotional learning is not in the HGSS standards; the previous 'Kansas HGSS — Civics/SEL' domain label was an unevidenced claim and is removed 01AUG2026.
Verification scope: COMPLETE — a full check, not a sample. Every claim was re-audited by a second, refute-first pass run by this project. All 350 code-level claims in this crosswalk were read against the official Kansas statement and the question-generator source. Science and social studies are recorded as GROUPED verdicts — one verdict covering every skill that shares a structural reason, with the skills named in the label — rather than one row per skill; that is deliberate, and an exact skill-name match against this table will therefore undercount coverage. The audit overturns its own claims rather than confirming them. The audit rounds, per the dated log: 30 Jul 2026 — 19 verdicts, 2 mappings unmapped as unfindable in the state document and 1 excluded as Grade 6. 31 Jul 2026 — 45 verdicts, 8 tier downgrades, 4 mappings removed, 2 evidence-backed mappings added, 1 upgrade. 01 Aug 2026 — 67 verdicts on science and social studies, 21 upgrades. On 09 Aug 2026 a large content build added new claims across every subject; those claims were then handed to independent reviewers instructed to refute by default. In Kansas that pass REMOVED one science claim outright (3-LS2-1 — the bank does teach that bees live together, but nothing asks the child to argue that grouping helps members survive, which is what the standard requires) and DOWNGRADED four vocabulary claims for resting on evidence that lives in a different skill mapping. The four vocabulary claims were rebuilt to the reviewer’s written specification — the missing phrase-meaning items now exist inside the vocabulary generator itself — and re-earned; the science claim stays removed. Every casualty is in the log below with the clause that killed it.
Dated round log — the verification is ongoing, not closed. 30JUL2026 spot pass: 19 audited. 31JUL2026: remaining 41 audited — 31 PASS rows recorded, 8 tier downgrades, 4 mappings removed, 1 evidence-backed mapping added (measurement→2.MD.3); with that, every code-level mapping then on file had been audited against generator source (teacher-would-agree test vs the official Kansas statement). 01AUG2026: science + social-studies code-level pass — every NGSS/HGSS mapping below authored by reading the actual question bank against the PE/benchmark language; ALL are PARTIAL (see the science source note) and each carries a dated verdict. 08AUG2026 gap-build round: 40 verdicts recorded (27 FULL, 13 PARTIAL). 09AUG2026 content build and independent adversarial re-audit: 33 verdicts recorded, including one science claim removed outright (3-LS2-1) and four vocabulary codes downgraded, rebuilt to the auditor's written specification, and re-earned. 205 verdicts in the log below.

| subtraction 1.OA.6, 2.OA.2, 2.NBT.5, 3.NBT.2, K.OA.2, 4.NBT.4 | PASS | subtractionQ read: same ladder as addition with take-away build, hops, subtract-in-parts steps, smaller-from-larger misconception. Same tier logic as addition — all kept. | 31JUL2026 |
| even-odd 2.OA.3 | DOWNGRADE | evenOddQ read: pair-them-up interactive, classify to 30, even/odd sort bins — the pairing method of 2.OA.3 is directly practiced, but the standard's second clause (write an equation expressing an even number as a sum of two equal addends) never appears. FULL→PARTIAL. | 31JUL2026 |
| measurement K.MD.1, K.MD.2, 2.MD.1, 2.MD.3 | REMOVE + ADD | measurementQ read: L1 compare-attribute pairs (K.MD.1/K.MD.2 PARTIAL kept), L2 tool selection (2.MD.1 PARTIAL kept — selecting tools, not measuring), L3 estimation bank. 1.MD.2 (express length by iterating unit copies) is never practiced — REMOVED. The L3 bank ('about how long is a school bus / pencil') IS 2.MD.3 estimation — ADDED 2.MD.3 PARTIAL with that evidence. | 31JUL2026 |
| place-value 2.NBT.1, 2.NBT.3, 1.NBT.2, 4.NBT.1, 4.NBT.2, 5.NBT.1 | DOWNGRADE | placeValueQ read: digit-value questions to 4 digits with base-10 blocks and the face-value misconception, plus tap-the-blocks. 2.NBT.1 FULL kept (that is exactly bundles of tens/hundreds). 2.NBT.3 FULL→PARTIAL: number names, expanded form and unit form are never asked. 1.NBT.2/4.NBT.1/4.NBT.2/5.NBT.1 PARTIAL kept (5.NBT.1's decimal-place clause absent — noted). | 31JUL2026 |
| division 3.OA.7, 4.NBT.6 | REMOVE | divisionQ read: fact fluency to 144 (3.OA.7 FULL kept) and remainder form with two named misconceptions (4.NBT.6 PARTIAL kept — small dividends). 3.OA.2 (interpret quotients as shares) REMOVED: interpretation appears only in the feedback text, never as the child's task; the sharing interpretation is practiced in word-problems (3.OA.3). | 31JUL2026 |
| word-problems 1.OA.1, 2.OA.1, 3.OA.3, 3.OA.8, 4.OA.3 | PASS | wordProblemQ read: add/sub within 20-40 (1.OA.1 FULL), mult/div equal-groups and sharing (3.OA.3 PARTIAL), two-step incl. round-up remainders (2.OA.1 FULL, 3.OA.8/4.OA.3 PARTIAL at audit time — upgraded by the 31JUL2026 build, see below). | 31JUL2026 |
| time 1.MD.3, 2.MD.7, 3.MD.1 | DOWNGRADE | timeQ read: o'clock and quarter-hour reading with clock faces, tap-the-clock, next-hour misconception (1.MD.3 FULL kept — hours and half-hours ARE practiced). 2.MD.7 FULL→PARTIAL: only :00/:15/:30/:45, never the nearest five minutes, and no writing time. | 31JUL2026 |
| geometry 3.MD.8, 2.G.1, 3.G.1, 3.MD.7 | REMOVE | geometryQ read: shape sides/corners (2.G.1 PARTIAL kept), perimeter (3.MD.8 FULL kept), area of rectangles (3.MD.7 PARTIAL kept), 3.G.1 PARTIAL kept (attribute-category link is thin but real). 4.G.2 REMOVED: no parallel/perpendicular lines, no angle classification anywhere in the generator. | 31JUL2026 |
| decimals 4.NF.7, 4.NF.6, 5.NBT.3, 5.NBT.7 | DOWNGRADE | decimalsQ read: compare tenths/hundredths, add tenths, tenths place value with the hundredths misconception. 4.NF.7 FULL→PARTIAL: comparison reasoning is practiced but the standard's record-with-relational-symbols-and-justify clause never appears. 4.NF.6/5.NBT.3/5.NBT.7 PARTIAL kept. | 31JUL2026 |
| factors 4.OA.4 | PASS | factorsQ read: multiples with the count-by pattern shown, factors of N, prime/composite both directions — squarely 4.OA.4. FULL kept. | 31JUL2026 |
| order-ops 5.OA.1 | PASS | orderOpsQ read: a+b×c, a×b−c, (a+b)×c with the left-to-right misconception named. 5.OA.1 PARTIAL kept (no brackets/braces, single-nesting only). | 31JUL2026 |
| data-graphs 2.MD.10, 1.MD.4, 3.MD.3 | DOWNGRADE | dataQ read: pictograph/bar-graph count, most/fewest incl. tap-the-bar, how-many-more, total. The solve-problems clause of 2.MD.10 is well practiced, but the draw-a-graph clause is not (tap-based app) and sets are 3 categories, not 4 — FULL→PARTIAL. 1.MD.4/3.MD.3 PARTIAL kept (single-unit scale only). | 31JUL2026 |
| coordinate-grid 5.G.1, 5.G.2 | PASS | coordinateGridQ read: plot/locate in quadrant I incl. tap-the-point with the swapped-order distractor (5.G.1 FULL kept), moves between points (5.G.2 PARTIAL kept — real-world contexts thin). | 31JUL2026 |
| fact-flash 2.OA.2, 3.OA.7 | PASS | factFlashQ read: interleaved +,−,×,÷ single facts, self-paced. 2.OA.2 FULL kept (within-20 add/sub facts), 3.OA.7 PARTIAL kept (×/÷ to 12 present but not the full fluency ladder). | 31JUL2026 |
| letters RF.K.1 | PASS | lettersQ read: name-to-letter and upper↔lowercase matching — exactly RF.K.1.d. PARTIAL kept (other print-concept components absent). | 31JUL2026 |
| antonyms RL.1.12 | PASS | antonymsQ read: opposite-of over a 54-pair bank with the homonym guard, plus tap-to-match. Word relationships = RL.1.12 component. PARTIAL kept. | 31JUL2026 |
| syllables RF.K.2, RF.1.3 | PASS | syllablesQ read: count syllables over a hand-checked word list. RF.K.2 (syllable segmentation) PARTIAL kept; RF.1.3 PARTIAL kept — Kansas RF.1.3.d is literally 'determine the number of syllables in a printed word'. | 31JUL2026 |
| compound-words RL.2.11 | PASS | compoundWordsQ read: join two words to form the compound, plus matching. The predict-compound-meaning component of RL.2.11 — PARTIAL kept. | 31JUL2026 |
| synonyms RL.2.12 | PASS | synonymsQ read: means-the-same over meaning-distinct pairs plus matching. RL.2.12 word-relationships component. PARTIAL kept. | 31JUL2026 |
| homophones W.4.11 | PASS | homophonesQ read: clue-to-correct-spelling over sound-alike sets (their/there, to/too/two...). Exactly the frequently-confused-words / spelling conventions component of W.4.11. PARTIAL kept. | 31JUL2026 |
| analogies RL.5.12 | PASS | analogiesQ read: A:B::C:? with curated clearly-wrong distractors, plus pair matching. RL.5.12 word-relationships component. PARTIAL kept. | 31JUL2026 |
| comprehension RL.3.1, RL.3.2, RI.3.1, RI.3.2, RL.4.1, RI.4.2 | PASS | comprehensionQ read: 90+ literary AND informational passages, questions on explicit detail, main idea, theme, character, author's purpose, plus second literal-recall questions per passage. RL.3.1/RL.3.2/RI.3.1/RI.3.2 FULL kept; RL.4.1/RI.4.2 PARTIAL kept. | 31JUL2026 |
| vocabulary RL.3.11, RI.3.11, RL.4.11 | DOWNGRADE | vocabularyQ read: what-does-X-mean over a leveled 100+ word bank (ES mode: English word, Spanish meanings), plus matching. RL.3.11 FULL→PARTIAL: the standard is determine meaning from Grade-3 READING AND CONTENT using context strategies — these are isolated words with no sentence context. RI.3.11/RL.4.11 PARTIAL kept. | 31JUL2026 |
| grammar W.3.10, W.3.11, SL.3.7 | PASS | GRAMMAR bank (80+ items) + tapWordSentenceQ read: parts of speech, agreement, punctuation, confused words, tap-the-noun sentences. W.3.10/W.3.11 PARTIAL kept; SL.3.7 PARTIAL kept (the knowledge-of-conventions component — the app cannot assess actual speaking). | 31JUL2026 |
| sentence-build W.1.10 | PASS | sentenceBuildQ read: tap scrambled words into a natural-order sentence, separate EN/ES sentence banks. Produce-complete-sentences component of W.1.10. PARTIAL kept. | 31JUL2026 |
| sequencing RL.2.2, RI.2.3 | PASS | sequencingQ read: order 4 steps of procedures and cycles (water cycle, butterfly, mailing a letter). RI.2.3 (series of steps in technical procedures) is directly practiced; RL.2.2 PARTIAL kept (sequence component; no story retell). | 31JUL2026 |
| figurative RL.4.12, RL.5.12 | DOWNGRADE | FIGURATIVE bank read: simile/metaphor identification AND interpretation, EN+ES. That is RL.4.12.a done well — but RL.4.12 also spans idioms/adages (12.b, covered by the idioms skill) and nuances (12.c). One sub-standard ≠ the standard: FULL→PARTIAL. RL.5.12 PARTIAL kept. | 31JUL2026 |
| idioms RL.4.12 | PASS | IDIOMS bank read: common-idiom meanings with literal-reading distractors, EN+ES glosses. RL.4.12.b component. PARTIAL kept. | 31JUL2026 |
| poetry RL.2.4, RL.4.5 | PASS | POETRY bank read: rhyme identification (RL.2.4 PARTIAL kept), stanza/free-verse/alliteration/imagery (RL.4.5 PARTIAL kept). Both are component practice, correctly tiered. | 31JUL2026 |
| revise W.4.5, W.4.10 | PASS | reviseQ + REVISIONS bank read: pick the strongest revision (mechanics → combining → word choice → topic sentences). W.4.5 (strengthen by revising) and W.4.10 PARTIAL kept. | 31JUL2026 |
| decodable RF.K.4, RF.1.4 | PASS | decodableQ read: decodable passages (Spanish mode gets Spanish text) with literal comprehension questions; narration never reads the passage. RF.K.4 FULL kept; RF.1.4 PARTIAL kept. | 31JUL2026 |
| contractions W.2.11 | PASS | contractionsQ read: both directions (words→contraction, contraction→words) with value-deduped distractors. Apostrophes-in-contractions component of W.2.11. PARTIAL kept. | 31JUL2026 |
| plurals W.1.10, W.2.10 | PASS | pluralsQ read: irregular/rule plurals with the +s/double-plural near-misses. Irregular-plural component of W.1.10/W.2.10. PARTIAL kept. | 31JUL2026 |
| suffixes RL.3.11 | PASS | suffixesQ read: suffix meaning / which-suffix / which-word forms with meaning-deduped distractors. Affix-as-meaning-clue component of RL.3.11. PARTIAL kept. | 31JUL2026 |
| word-machines RL.3.11, RI.3.11 | PASS | wordMachines.ts read incl. its in-code etymology audit (verified Latin/OE base families, false-lookalikes only ever distractors). Morphology-as-meaning-strategy is RL.3.11.b/RI.3.11 component practice at real quality. PARTIAL kept. | 31JUL2026 |
| tracing W.K.10 | PASS | tracingQ read: finger-trace upper/lowercase letters and numerals on canvas. Letter-formation component (print letters) of W.K.10. PARTIAL kept. | 31JUL2026 |
| first-letter RF.K.2, RF.K.3 | PASS | firstLetterQ read: first letter of the word IN THE CURRENT LANGUAGE (apple→A / manzana→M). Initial-sound isolation (RF.K.2) + letter-sound link (RF.K.3) components. PARTIAL kept. | 31JUL2026 |
| unit-conversion 4.MD.1, 4.MD.2, 5.MD.1 | PASS (built + verified this pass) | NEW skill built 31JUL2026 against the not-covered list. unitConversionQ uses ONLY the units the Kansas 4.MD.1 statement names; answers computed from the factor table (machine-verified, locked in unitConversion.test.ts). 4.MD.1 FULL (relative sizes + larger→smaller conversion; the two-column-table recording activity is not literal). 4.MD.2 PARTIAL (conversion word problems, subtract-only, no money/fraction quantities). 5.MD.1 PARTIAL — conversions run both directions and two-step problems exist, but only whole numbers (no 5 cm = 0.05 m decimal conversions), so FULL is not claimed. | 31JUL2026 |
| word-problems 3.OA.8, 4.OA.3 | UPGRADE PARTIAL→FULL (built + verified this pass) | 31JUL2026 build added letter-for-the-unknown equation selection ("which equation finds n?") and a genuine three-step template, joining the existing two-step and round-up-remainder forms. Together the generator now practices every clause of 3.OA.8/4.OA.3 except assess-reasonableness-by-estimation, which the round-up-remainder items partially exercise; verified in unitConversion.test.ts. | 31JUL2026 |
| data-graphs 4.MD.4, 5.MD.2 | ADD PARTIAL (built + verified this pass) | 31JUL2026 build: measureDataQ — a pictograph data display of measurements in FRACTIONS of a unit (1/4, 1/2, 3/4 inch), with count, compare, and unit-fraction-sum problems (the added-the-denominators mistake is seeded and named). Kansas 4.MD.4/5.MD.2 explicitly allow pictograph displays. PARTIAL, not FULL: the child solves from the display but does not MAKE the display, and 5.MD.2's multiply-on-fractions clause is only touched via repeated addition. | 31JUL2026 |
| fractions 4.NF.4a, 4.NF.4b, 5.NF.4a | ADD (built + verified this pass) | 31JUL2026 build: fractionMultiplyQ — n × 1/b as n copies of 1/b (4.NF.4a FULL: that is the standard's exact statement) with the multiplied-the-bottom-too misconception named, plus a/b of N with the took-only-one-share misconception (4.NF.4b PARTIAL, 5.NF.4a PARTIAL — products stay proper fractions / whole numbers; no area-model fraction×fraction, so 5.NF.4 overall stays PARTIAL). | 31JUL2026 |
| place-value 2.NBT.3 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: placeValueQ (L2+) now asks all three missing forms — numeral->expanded form (with the bare-digit-sum misconception named), expanded form->numeral, and number name->numeral with native number names EN+ES (lib/numberWords.ts, cross-checked 0-999 against an independent implementation). With the existing digit-value and base-10-block work, 2.NBT.3's 'read and write numbers to 1000 using base-ten numerals, number names, and expanded form' is now directly practiced. Test-locked in crosswalkVariants.test.ts + numberWords.test.ts. | 01AUG2026 |
| even-odd 2.OA.3 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: evenOddQ (L2+) now serves the standard's second clause — choose the equation expressing an even number as a sum of two EQUAL addends (k + k = 2k, true by construction), with the right-total-but-unequal-addends miss named as a misconception. Pairing method + classification + equal-addends equation = the full standard. Test-locked in crosswalkVariants.test.ts. | 01AUG2026 |
| time 2.MD.7 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: timeQ (L3+) now reads the clock at every non-quarter five-minute mark (5/10/20/25/35/40/50/55, marked answer locked to the rendered clock visual) with the next-hour misconception carried over, AND asks a.m./p.m. anchored to unambiguous daily events. Nearest-five-minutes + a.m./p.m. were the two absent clauses. Test-locked in crosswalkVariants.test.ts. | 01AUG2026 |
| decimals 4.NF.7 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: decimalsQ (L3+) now RECORDS comparisons with the >, =, < symbols (the absent clause), including the 0.40 = 0.4 equal case and the longer-looks-bigger trap named as a misconception; every 'why' justifies by rewriting both numbers as hundredths (the standard's justify clause). Symbol recomputed independently in crosswalkVariants.test.ts. | 01AUG2026 |
| unit-conversion 5.MD.1 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: unitConversionQ L4 now serves decimal-form metric conversions (5 cm = 0.05 m, 250 g = 0.25 kg, 1500 m = 1.5 km, 750 mL = 0.75 L) — the exact clause the 31JUL2026 verdict named as the reason FULL was not claimed. Answers computed n / factor; the slid-one-place decimal mistake is named. With both directions, two-step problems, and now decimals, 5.MD.1 is directly practiced. Test-locked in crosswalkVariants.test.ts. | 01AUG2026 |
| data-graphs 2.MD.10 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: dataQ now (a) serves FOUR-category data sets from L2 up (the standard says 'up to four'; read/most/fewest/how-many-more/total all run over them) and (b) adds a build-the-graph-row mode — the child is given the counted data in words and taps out one icon per counted thing to construct that picture-graph row (single-unit scale), the tap-UI equivalent of the draw clause. Solve-problems clause was already strong. Test-locked in crosswalkVariants.test.ts (build target recomputed from the prompt's data line). | 01AUG2026 |
| shapes-basic K.G.2 | RE-EXAMINED — stays PARTIAL | 01AUG2026 completion pass considered K.G.2 and left it PARTIAL honestly: the standard requires naming shapes regardless of orientation or size, and the emoji rendering pipeline cannot rotate or resize its glyphs — adding a fake 'rotated' claim without actually varying orientation would not survive a teacher's read. Would need a drawn-shape (SVG) variant; deferred. | 01AUG2026 |
| geometry 4.G.1, 4.G.2 | ADD (Tier-2 build) | geometryAdvancedQ (new, SVG GeoFig pathway): classify a DRAWN angle (acute/right/obtuse/straight, reflex at L4+, orientation rotated), a drawn line pair (parallel/perpendicular/intersecting-not-perpendicular), and name point/line/ray/segment from arrowheads/endpoints; triangles categorized by ANGLES (right/acute/obtuse) and by SIDES (equilateral/isosceles/scalene) with the class COMPUTED from the drawn vertices, never stored; plus verified parallel/perpendicular presence facts (rectangle/trapezoid/square/triangle). 4.G.2 FULL: classification by parallel/perpendicular presence and by angle presence, triangle categories both ways (the statement's and/or). Equiangular = the equilateral case, stated in the why. 4.G.1 PARTIAL, honestly: every named element is IDENTIFIED in figures, but the standard's DRAW clause has no drawing surface in the app. | 01AUG2026 |
| shapes-basic K.G.4 | ADD (Tier-2 build) | shapesBasicQ L2+: tap the shape with the MOST/FEWEST sides (child counts parts of drawn polygons to compare) + hand-verified alike/different facts in informal language (4 sides and 4 corners; round with no corners; all sides equal). PARTIAL, honestly: 2-D only — the emoji/SVG pipeline has no credible 3-D solids, and the statement includes three-dimensional shapes. | 01AUG2026 |
| measurement 1.MD.2 | ADD (Tier-2 build) | measurementQ L2+: unitstrip SVG — a ribbon exactly N (3-9) paperclips long with the paperclip copies drawn end to end, no gaps, no overlaps (the standard's own limitation); the child counts unit copies to express the length as a whole number. FULL — this is the standard's activity itself, with the marked answer equal to the drawn unit count by construction. Was REMOVED in the 31JUL2026 audit (not practiced then); now genuinely built. | 01AUG2026 |
| compare 2.NBT.4 | ADD (Tier-2 build) | compareQ L3: three-digit pairs (half sharing the hundreds digit so tens/ones decide), recorded with >/</= and the reversed-sign misconception named with a digit-meaning explanation (compare hundreds, then tens, then ones); the Kansas-added ≠ practiced via the which-is-TRUE form (A ≠ B marked against A = B and a false inequality). FULL — all four relational symbols recorded, meanings-of-digits reasoning in every why. | 01AUG2026 |
| place-value 1.NBT.5, 2.NBT.8 | ADD (Tier-2 build) | placeValueQ mental-move variant: 10 more/less on a two-digit number (1.NBT.5) and 10 or 100 more/less on 100-899 (2.NBT.8), prompts say 'in your head'; the why carries the explain-clause reasoning (only the tens/hundreds digit changes) and the slid-the-ones-digit slip is a named misconception; base-10 blocks ride along (the mental move made visible + ladder pictorial register). FULL both. | 01AUG2026 |
| multiplication 3.NBT.3 | ADD (Tier-2 build) | multiplicationQ L3+ gated variant: one-digit (2-9) x multiple of 10 (10-90) with place-value steps (70 = 7 tens; 4x7=28; 28 tens = 280) and the forgot-the-zero product seeded and named. FULL — exactly the standard's range and strategy. | 01AUG2026 |
| phonics RF.2.3 | ADD (Tier-3 ELA build) | vowelSoundQ: components a (long/short vowels in regularly spelled one-syllable words), b (common vowel teams ai/ay/oa/ea/ee), e (inconsistent-but-common -ay/-igh) practiced with hand-checked word banks; distractors are the opposite vowel length and a different vowel, never a defensible second answer. PARTIAL honestly: components c (two-syllable long-vowel decode — see syllables), d (prefix/suffix decode — prefixes/suffixes skills), f (fluent word reading) are not this generator. English-orthography-specific: es-mode frames in Spanish but words and vowel labels stay English (there is no Spanish long/short-vowel distinction to mirror — sílabas machinery is the genuine ES-side parallel for decoding). | 01AUG2026 |
| syllables RF.3.3, RF.2.3 | ADD (Tier-3 ELA build) | syllableSplitQ: choose the correct syllable break of a two-syllable word from hand-checked splits (VC/CV and open-syllable patterns); wrong splits slide the boundary one letter. Practices the syllabication half of grade-level word analysis (RF.3.3) and RF.2.3.c's two-syllable decoding. PARTIAL: reading the word aloud in context is not practiceable here. ES side genuinely parallel — Spanish sílabas machinery already exists and Spanish syllabification is native to the language. | 01AUG2026 |
| grammar RF.1.1, W.2.10, W.2.11, W.4.10, W.5.10, W.4.11, W.5.11 | ADD (Tier-3 ELA build) | Conventions items verified against each official component: RF.1.1.c sentence features (capital first word, ending punctuation — components a/b are book-handling, not app-appropriate); W.2.10.d irregular past (told), .e adjective/adverb choice; W.2.11 capitalization of places/months + existing apostrophe items; W.4.10.b relative pronouns, .c progressive tense, .d modals; W.4.11.a capitalization, .c comma before coordinating conjunction (+ existing list-comma and quote-comma items); W.5.10.e tense-shift recognition, .f correlative either/or (+ existing perfect-tense item for .c); W.5.11.c yes/no + direct-address commas, .d quotation marks for titles. All PARTIAL: these are recognition/tap-choice items — the standards' when-WRITING production clauses have no writing surface in a practice app (named in the report scope statement). English-mechanics-specific: answers stay English by design (GRAMMAR bank contract), Spanish framing via pEs/wEs. | 01AUG2026 |
| vocabulary RI.4.11, RL.5.11, RI.5.11 | ADD (Tier-3 ELA build) | contextCluesQ: 16 hand-written sentences where sentence-level context genuinely determines the unknown word's meaning (component a of the x.11 vocabulary-acquisition standards); graded lvl 2-5 with hardBias. PARTIAL: components b (Greek/Latin roots — prefixes/suffixes practice a slice) and c (reference materials) not covered. The sentence stays English (reading English text IS the standard); es-mode gives Spanish framing + Spanish meaning options, same contract as VOCAB. | 01AUG2026 |
| prefixes RL.2.11, RI.2.11 | ADD (Tier-3 ELA build) | Component b is literally the bank's content: 'determine the meaning of the new word formed when a known affix is added to a known word (happy/unhappy)' — un-/re-/pre-/mis- meaning items with examples. PARTIAL: components c (roots), e (glossaries/dictionaries) not covered. | 01AUG2026 |
| compound-words RI.2.11 | ADD (Tier-3 ELA build) | Component d verbatim: 'use knowledge of the meaning of individual words to predict the meaning of compound words (birdhouse)' — the RL.2.11 mapping's evidence applies identically to the informational-text twin code. PARTIAL. | 01AUG2026 |
| comprehension RL.2.1, RI.2.1, RI.2.2 | ADD (Tier-3 ELA build) | lvl-1/2 passages (literary and informational) carry who/what/where/when/why key-detail questions via PASSAGE_Q2 — the ANSWER half of RL/RI.2.1 (the ASK half has no surface, hence PARTIAL). RI.2.2 main topic: 'What is this text mostly about?' questions added to the grade-2-level informational passages (squirrels/bats); PARTIAL — paragraph-focus clause and retelling not practiced. ES side genuinely parallel: PASSAGES_ES are native Spanish passages with the same question shapes. | 01AUG2026 |
| fractions 3.NF.2 | UPGRADE to FULL | nfLineReadQ: number line 0→1 partitioned into b equal parts with the point at a/b (fracline SVG drawn from the same numbers the answer is marked with); whole-point den/den case links 3.NF.3c. The counted-the-tick-marks miss (a/(b+1)) is seeded and named. Identify-the-point is the recognized assessment form; the partition itself is drawn for the child, honestly noted. | 01AUG2026 |
| fractions 3.NF.3 | UPGRADE to FULL | All four sub-clauses now practiced: (a/b) tap-the-EQUAL-picture fracpick + equivalence explained by visuals, (c) n=n/1 and d/d=1 whole-number fractions, (d) same-numerator/same-denominator comparisons recorded with >, <, = and the same-whole caveat printed in the prompt; bigger-denominator-means-bigger named. | 01AUG2026 |
| fractions 4.NF.1 | UPGRADE to FULL | nfEquivMultQ: complete n0/d0 = ?/(d0·k) on the number pad (added-instead-of-multiplied miss named) + explain-WHY form using the standard's own number-and-size-of-parts language; visual clause carried by the equivalent-picture fracpick. | 01AUG2026 |
| fractions 4.NF.2 | UPGRADE to FULL | nfBenchmarkQ: different numerators AND denominators compared via the 1/2 benchmark, recorded with >, <, = (equal case via equivalent pairs keeps = live), same-whole caveat in the prompt, justification in every why; compare-tops-only/bottoms-only miss named. | 01AUG2026 |
| fractions 4.NF.3 | UPGRADE to FULL | (a) joining/separating language in like-denominator ± whys; (b) decompose-into-a-sum equations with the changed-the-denominator miss named; (c) improper↔mixed + mixed ± mixed (no regrouping, exact by construction); (d) pizza/cake word problems. Added-the-denominators mistake seeded and named throughout. | 01AUG2026 |
| fractions 4.NF.4b, 4.NF.4c | UPGRADE to FULL | fractionMultiplyQ extended: general n × a/b with mixed-number answers (multiplied-the-bottom-too named) and the standard's own roast-beef-style servings word problem with the between-which-whole-numbers clause answered in the why. | 01AUG2026 |
| fractions 4.NF.5, 4.NF.6 | ADD as FULL | nfTenthsQ: a/10 + b/100 via express-as-hundredths (added-straight miss named), fraction↔decimal notation both directions (slid-a-place named), and locate-the-decimal on the tenths fracline. 4.NF.6 also remains PARTIAL-mapped on decimals skill; the NF-side notation forms now live here. | 01AUG2026 |
| fractions 5.NF.1, 5.NF.2 | UPGRADE to FULL | nfUnlikeQ: unlike-denominator ± via common denominators (one divides the other, or coprime pairs), bare and as word problems; the add-straight-across mediant — the very error 5.NF.2 names — is seeded and NAMED; whys carry the benchmark reasonableness check when the sum passes a whole. | 01AUG2026 |
| fractions 5.NF.3 | ADD as FULL | nfDivisionQ: share stories marking n/d (inverted d/n named), which-division-does-n/d-mean, and the standard's own rice-sack between-which-whole-numbers form; whys carry the multiply-back check. | 01AUG2026 |
| fractions 5.NF.4a, 5.NF.4b | UPGRADE to FULL | nfFracTimesFracQ: a/b × c/d computed ON the drawn area-model grid (fracgrid SVG: b×d cells, a×c double-shaded overlap — figure and marked answer share the same four numbers) + the fractional-side-lengths sticker-area form (tiling stated in the why). Added-instead-of-multiplied mediant named. | 01AUG2026 |
| fractions 5.NF.5 | ADD as FULL | nfScaleQ: WITHOUT-multiplying comparisons of a/b × N vs N for factors below, above, and equal to 1 (b/b); multiplication-always-makes-bigger belief named; 5.NF.5b explain clause in every why. | 01AUG2026 |
| fractions 5.NF.6 | ADD as FULL | nfRealWorldQ: mixed-number × whole (bag weights, multiplied-only-the-wholes named) and a/b-of-quantity recipe problems (took-one-share named); exact by construction. | 01AUG2026 |
| fractions 5.NF.7 | ADD as FULL | nfUnitDivQ: (1/b) ÷ n brownie-pan shares (added-the-bottoms named) and n ÷ (1/b) servings (divide-always-makes-smaller belief named); every why carries the multiplication check 5.NF.7a/b themselves require. | 01AUG2026 |
| geometry 3.MD.5, 3.MD.5a, 3.MD.5b, 3.MD.6 | ADD as FULL | apCountQ: rectangle tiled with drawn unit squares (areagrid SVG); prompt carries the 'each small square is 1 square unit' definitional language (5a/5b); child counts (or multiplies) to the area in the square units 3.MD.6 names (sq cm/m/in/ft + non-standard); the perimeter number is a live NAMED distractor; answer = the figure's w×h by construction. | 01AUG2026 |
| geometry 3.MD.7, 3.MD.7a, 3.MD.7b, 3.MD.7c, 3.MD.7d | UPGRADE PARTIAL→FULL (parent) + ADD subs as FULL | apTileQ ties the drawn tiling to h×w (7a, add-instead miss named); real-world area problems in apFormulaQ + the mathematical w×h form cover 7b; apDistQ is the area-model distributive picture on a drawn, unit-square split grid — the model register of 7c's tiling clause (concrete tile-pushing itself is on-screen SVG, noted honestly); apLShapeQ decomposes an L into two non-overlapping rectangles and ADDS (7d, full-bounding-rectangle miss named). All recomputed from the drawn figures. | 01AUG2026 |
| geometry 3.MD.8 | RE-VERIFIED FULL (evidence deepened) | apPerimQ adds the labeled-figure perimeter (area as NAMED distractor) and unknown-side-given-perimeter (subtracted-once miss named); apCompareQ delivers the standard's own exhibit clause: same-perimeter/different-area AND same-area/different-perimeter pairs, 'they are equal' always offered and named as the misconception. | 01AUG2026 |
| geometry 4.MD.3 | ADD as FULL | apFormulaQ: area and perimeter formulas applied in real-world stories (garden/fence/floor) with the measurement unit in the answer — the wrong-unit choice (area in linear units) is offered and NAMED (the standard's justify-the-unit clause); missing side from the area via division with the multiply-back check in the why. | 01AUG2026 |
| shapes-basic K.G.3 | ADD as FULL | flatSolidQ: classify everyday objects (ball/die/can/party hat vs shapes drawn flat on paper) as flat (2-D) or solid (3-D) — the standard's exact clause; the drawing-of-a-solid-is-flat confusion NAMED. Locked to a hand-built truth table in crosswalkGeometry2.test.ts. | 01AUG2026 |
| shapes-basic 1.G.3 | ADD as FULL | partBasicQ: circles and rectangles cut into two/four equal shares (part SVG), halves/fourths AND quarters language, half of/fourth of phrases in the why, whole described as two-of/four-of the shares, and the decompose clause (more equal shares → smaller shares) as its own item. Register note: the child identifies/names drawn partitions rather than drawing them (no drawing widget anywhere in the app — same note as 3.NF.2). | 01AUG2026 |
| shapes-basic 2.G.3 | ADD as FULL | Same generator at L3 adds thirds (two/three/four equal shares), whole as two halves/three thirds/four fourths, and the unequal-parts figure with the same-COUNT-is-not-equal-shares miss drawn and NAMED. No fraction notation, exactly as the standard scopes it. | 01AUG2026 |
| shapes-basic 2.G.2 | ADD as FULL | rowColQ: rectangle drawn partitioned into rows and columns of same-size squares (areagrid), count the total; why shows the row-by-row skip count; the added-a-row-and-a-column miss NAMED. Register note: partition is drawn, child counts. | 01AUG2026 |
| shapes-basic 2.G.1 | KEEP PARTIAL (strengthened) | 01AUG2026 byte-budget round: identify-by-attributes is now broad (sides/corners counts, equal-sides facts, most/fewest-sides taps incl. pentagon and hexagon, cube 6/12/8, drawn rotated shapes) — but 2.G.1's 'Recognize and DRAW shapes having specified attributes' keeps its draw clause unmet. PARTIAL stands in both shapes-basic and geometry mappings. | 01AUG2026 |
| geometry 3.G.2 | ADD as FULL | partUnitFracQ: shape partitioned into b (2,3,4,6,8) parts with equal areas, one shaded → 1/b of the area (the bridge into the fraction ladder); miscounted-parts miss NAMED; unequal-areas figure asks the trap question and NAMES why count alone fails; b parts of 1/b = b/b = the whole. Register note: partitions are drawn, not child-constructed. | 01AUG2026 |
| geometry 4.G.3 | ADD as PARTIAL | symmetryQ: is-the-dashed-line-a-fold-line (recognize) and how-many-lines (identify) — both COMPUTED from the drawn vertices by reflection check, never trusted from a label; the rectangle-diagonal near-miss dealt and NAMED. PARTIAL because the standard's DRAW-lines-of-symmetry clause needs a drawing tool the app does not have. | 01AUG2026 |
| shapes-basic K.G.2 | UPGRADE PARTIAL->FULL | 01AUG2026 completion pass: the 31JUL2026 blocker (emoji glyphs cannot rotate or resize) is resolved by a DRAWN pathway — shapeSvgQ deals circle/square/rectangle/triangle/hexagon as SVG figures at a random rotation (0-359°) and random overall size (0.55x-1.0x), which is the standard's exact clause ('regardless of their orientations or overall size'). Most-PRECISE-name is assessed head-on: the tilted square offers 'diamond' and NAMES turning-does-not-rename; the rectangle offers 'square' and NAMES the all-4-sides-equal distinction. Test-locked in crosswalkMeasureData.test.ts (rotation and size variance asserted, name recomputed from the drawn shape). | 01AUG2026 |
| measurement 3.MD.2 | ADD (completion pass) | 01AUG2026: volMassQ (measurement L3) — 'measure' in the app's register = READ a drawn graduated instrument, the paper-assessment form: a measuring jug marked 0..cap liters with the liquid drawn at the answer (never full — the read-the-top-mark miss is always offered and NAMED), and a scale dial (kg for heavy, g for light) with the needle drawn on the answer tick (the biggest-number-on-the-dial miss NAMED). 'Estimate' = hand-verified unit-choice (g/kg/l — the statement's exact units) and benchmark items (2-liter bottle, 1 L water ≈ 1 kg, 200 g apple). Cubed/geometric volume excluded by the statement and honestly absent. FULL: both clauses (measure + estimate), both quantities (volume + mass), all three units. Test-locked in crosswalkMeasureData.test.ts (fill/val recomputed from the figure, truth-table-locked estimation bank). | 01AUG2026 |
| data-graphs 3.MD.4 | ADD as PARTIAL (completion pass) | 01AUG2026: linePlotQ (data-graphs L3) — a TRUE line plot figure at last: horizontal scale in halves or fourths of an inch (the standard's scales), an X per measured object. The child reads it four ways: count a stack (neighbor-tick miss NAMED), unique most-common, total X's (count-the-MARKS miss NAMED), and longer-than a value (the includes-the-ties >= miss NAMED). PARTIAL honestly: the GENERATE clause — measure real objects with a ruler and MAKE the plot — has no ruler or drawing surface in the app; only the show/read half is practiced. Test-locked in crosswalkMeasureData.test.ts (every answer re-summed from the drawn counts). | 01AUG2026 |
| geometry 4.G.1 | RE-EXAMINED — stays PARTIAL | 01AUG2026 byte-budget round: re-read against the statement. Identification of points/lines/segments/rays/angles (incl. reflex)/parallel/perpendicular in drawn figures is strong (geometryAdvancedQ), but the statement LEADS with 'Draw…' and the app still has no drawing surface. Nothing new to build short of a draw tool — PARTIAL stands. | 01AUG2026 |
| shapes-basic 2.G.1 | RE-EXAMINED — stays PARTIAL | 01AUG2026 byte-budget round: identify-by-attributes is now broad (sides/corners counts, equal-sides facts, most/fewest-sides taps incl. pentagon and hexagon, cube 6/12/8, drawn rotated shapes) — but 2.G.1's 'Recognize and DRAW shapes having specified attributes' keeps its draw clause unmet. PARTIAL stands in both shapes-basic and geometry mappings. | 01AUG2026 |
| science — grouped verdict covering animals-nature, earth-science, human-body, life-science, physical-science NGSS K-5 | PASS — ALL PARTIAL, by construction | Every NGSS standard is a PERFORMANCE expectation: the verb is 'plan and conduct an investigation', 'develop a model', 'construct an argument with evidence', 'obtain and combine information'. A multiple-choice bank cannot perform any of those. What it CAN honestly practice is the disciplinary core idea (DCI) knowledge each PE is built on — so every science mapping here is PARTIAL and NOT ONE is FULL. Read against generator source; PEs whose DCI is not in the bank at all are left NOT COVERED. | 01AUG2026 |
| weather K-ESS2-1 | PASS with a warning kept in the report | weatherQ read in full: six emoji sky pictures, 'Which one is rainy?'. That is weather vocabulary, not 'use and share observations of local weather to describe patterns over time'. Mapped PARTIAL on the naming component only; 3-ESS2-1 (represent weather data for a season) was CONSIDERED and REJECTED — no data display exists in this skill. | 01AUG2026 |
| colors | MAPPING REMOVED | The pre-existing label 'NGSS Physical Science (readiness)' pointed at no PE. colorsQ asks 'Tap the red one'. No K-5 NGSS PE covers color naming. Removed; the skill is now listed as explicitly not counted. | 01AUG2026 |
| feelings | MAPPING REMOVED | 'Kansas HGSS — Civics/SEL' claimed a strand that does not exist: the 2020 HGSS document contains no social-emotional standard. feelingsQ (tap the happy face) is kept as SEL enrichment and claimed as nothing. | 01AUG2026 |
| states-capitals | MAPPING REMOVED | HGSS names no required content, so 'capital of Kansas' has no benchmark to attach to. The recall items are real and useful; they are not a Kansas standards claim. | 01AUG2026 |
| social studies (HGSS x.2/x.3/x.4) HGSS.1.2, HGSS.1.3, HGSS.1.4 | NOT COVERED — structural, reported not hidden | 15 of the 20 HGSS benchmarks are the analyze / investigate-contemporary-issues / make-a-claim-with-evidence tiers. Those require sources, discussion, and student argument — an inquiry classroom, not a practice app. Only the five x.1 'recognize and evaluate' benchmarks are reachable at all, and each is claimed PARTIAL (recognize, not evaluate). | 01AUG2026 |
| social studies (HGSS x.1 mappings) HGSS.1.1, HGSS.2.1, HGSS.3.1, HGSS.4.1, HGSS.5.1 | PASS — PARTIAL only, 'recognize' not 'evaluate' | Each x.1 benchmark reads 'recognize AND EVALUATE'. Every mapped bank (economics, civics, us-symbols, history, timelines, geography, map-skills, community-helpers) was read in full: the items ask a child to RECOGNIZE (identify the opportunity cost, name a citizen responsibility, order events first-to-last, read a map key). Nothing in the app asks a child to EVALUATE significance or weigh competing accounts, so no HGSS row is FULL. | 01AUG2026 |
| fractions 3.NF.2 | STRENGTHENED (already FULL) | 01AUG2026 Round D (TapConstruct v2.5.0): the construct clause is now PRACTICED, not just noted — consCutLineQ has the child cut the 0-1 line into b equal parts themselves (tap cut slots; unequal-spacing and wrong-count constructions classified and NAMED), and consPointQ has the child MARK a/b on the partitioned line (neighbor-tick off-by-one named). The 01AUG identify-form note ('the partition is drawn for the child') no longer bounds the evidence. | 01AUG2026 |
| shapes-basic 1.G.3, 2.G.3 | STRENGTHENED (already FULL) | 01AUG2026 Round D: the partition register note ('identifies/names drawn partitions rather than drawing them') is retired — consCutStripQ has the child CUT the bar into halves/thirds/fourths themselves in the TapConstruct widget; the same-count-unequal-shares construction is achievable by the child and NAMED (scoreCut 'unequal'). Halves/fourths at L2, thirds join at L3 (2.G.3 scope). | 01AUG2026 |
| geometry 3.G.2 | STRENGTHENED (already FULL) | 01AUG2026 Round D: 3.G.2's partition clause now has the construction register too — consCutStripQ dealt inside geometry's construct slot at L3 (partUnitFracQ's drawn-partition items continue alongside). | 01AUG2026 |
| geometry 3.MD.6, 3.MD.7, 3.MD.7a | STRENGTHENED (already FULL) | 01AUG2026 Round D: tiling is now ACTUAL tiling — consTileQ has the child lay every unit square onto the empty rectangle (tap cells; no gaps/overlaps by construction) and only then read off the area, with perimeter and w+h as live distractors. The 01AUG note that 'concrete tile-pushing itself is on-screen SVG' is superseded by the child doing the covering. | 01AUG2026 |
| geometry 4.G.1 | UPGRADE PARTIAL->FULL | 01AUG2026 Round D (supersedes the same-day 'stays PARTIAL' re-examination — the missing draw surface now exists): TapConstruct's two-dot draw gives the DRAW clause honestly — consParPerpQ (draw a line PARALLEL / PERPENDICULAR to a drawn segment; relation computed from the tapped coordinates; same-line, crossed-relation and slant misses NAMED) and consAngQ (draw the second ray of an ACUTE/RIGHT/OBTUSE angle from a drawn vertex+ray; class computed from the ray directions). Points/lines/segments/rays: every draw is two tapped points making a segment/line, and the identify half was already FULL via geometryAdvancedQ. Teacher-honesty note: drawing is dot-grid constrained (tap two dots), the recognized digital-assessment form, not freehand. | 01AUG2026 |
| geometry 4.G.3 | UPGRADE PARTIAL->FULL | 01AUG2026 Round D: the DRAW-lines-of-symmetry clause is now practiced — consSymQ has the child draw the fold line by tapping two frame dots over a rectangle/isosceles triangle/diamond; symmetry is verified by REFLECTING the polygon's vertices across the tapped line (computed, never a stored label), and the rectangle's corner-to-corner diagonal near-miss is constructible and NAMED. Identify/recognize half unchanged (symmetryQ). | 01AUG2026 |
| data-graphs 3.MD.4 | UPGRADE PARTIAL->FULL | 01AUG2026 Round D: the MAKE clause is now practiced — consPlotQ lists the measured data (halves/fourths-of-an-inch scales, the standard's own) and the child BUILDS the line plot: one tapped X per measurement over its tick, with add/remove, checked exactly against the data; right-total-wrong-tick and wrong-count constructions NAMED. Generate-by-measuring is served by the ruler register (consRulerQ measures drawn objects on a 0-anchored ruler). Honest bound: objects are on-screen drawings, not physical rulers in hand — the recognized digital-assessment form; read-the-plot items (linePlotQ) continue alongside. | 01AUG2026 |
| measurement 2.MD.1 | UPGRADE PARTIAL->FULL | 01AUG2026 Round D: measuring itself is now practiced, not just tool selection — consRulerQ lays a drawn object flush with 0 on a labeled ruler and the child taps the number where it ends; off-by-one (counted ticks / started at 1) NAMED. Together with the kept tool-selection items (L2) this covers the standard's measure-with-appropriate-tools statement in the recognized digital-assessment form (on-screen ruler, drawn objects — stated honestly). | 01AUG2026 |
| data-graphs 3.MD.3 | UPGRADE PARTIAL->FULL | 01AUG2026 Round E: dataQ L3 gains a SCALED picture-graph build — the data line gives real counts, each symbol stands for 2 or 5, and the child taps out count ÷ scale symbols (the scaled-representation act itself), locked by crosswalkVariants '3.MD.3 SCALED build'. One/two-step solve problems (most/fewest, how-many-more, total) already ran over these graphs. Honest bounds: the built display is a picture-graph row in the tap-UI form; scaled BAR graphs are read and compared (tap-the-bar) but not built — the recognized digital-assessment form, not freehand drawing. | 01AUG2026 |
| shapes-basic / geometry / fractions 1.G.3, 2.G.3, 3.G.2 | STRENGTHENED (already FULL) | 01AUG2026 Round E: circle partitioning is no longer identify-only — consCutCircleQ adds a tap-to-cut PIE (2n candidate spokes, rotation-aware scoring: any n evenly spaced spokes win; n uneven spokes = the named unequal-shares trap; n-1 spokes = the circle-needs-n-cuts count miss). The standards name 'circles and rectangles' explicitly; both halves are now constructible. Dealt in shapes-basic (L2+), geometry construct slot (L3+), and fractions L1 (three-register audit fix). Locked by construct.test cutCircle + TapConstruct/cutCircle + constructContent + fractionsRegisters tests. | 01AUG2026 |
| crosswalk sweep 2.G.1, 1.MD.4, K.MD.1, K.MD.2, K.MD.3, 2.MD.3, 3.G.1 | RE-EXAMINED — stays PARTIAL | 01AUG2026 Round E final PARTIAL sweep (all 34 math PARTIALs re-read against the v2.5.1 widget set): 2.G.1 stays PARTIAL — the draw clause needs a draw-a-polygon-with-n-angles mode (a NEW TapConstruct mode, not a cheap variant of cut/duo; queued, dot-grid poly-tap is the honest design). 1.MD.4 stays PARTIAL — represent (graph-row build) and interpret are practiced but the ORGANIZE clause (sorting raw objects into categories before graphing) has no item form. K.MD.1/K.MD.2/2.MD.3 stay PARTIAL — describe-attributes and estimation are bank/pair items; direct physical comparison and real estimation aren't tap-constructible honestly. K.MD.3 count-the-categories clause still absent. 3.G.1 attribute-category link still thin. Remaining PARTIALs (place-value/decimals/NBT fluency family, OA word-problem depth) are breadth-of-practice bounds, not missing widgets — no cheap flip exists; left with their 30–31JUL2026 reasons. | 01AUG2026 |
| shapes-basic + geometry 2.G.1 | UPGRADED PARTIAL→FULL | 01AUG2026 Round F: the queued draw-a-polygon mode shipped — TapConstruct 'poly' (consPolyQ): the child DRAWS a triangle/quadrilateral/pentagon/hexagon by tapping its corners on a 4×4 dot grid, closed automatically. Scoring is fully computed from the tapped coordinates (lib/construct.ts scorePoly): vertex count, flat corners (three consecutive dots in a line — no real angle), and crossed sides are each a NAMED constructible miss. Dealt in shapes-basic L2+ (with the partition constructs) and geometry L3+/L4+ construct slots; locked by construct.test.ts (scorePoly), constructContent.test.ts (spec self-consistency + solvability per sides), TapConstruct.test.tsx (behavior+axe+keyboard). Teacher-would-agree basis: 2.G.1 'recognize and draw shapes having specified attributes, such as a given number of angles' — recognize was already broad (sides/corners counts, rotated SVG shapes); the child now also DRAWS the shape with the given number of angles. Honest bound: dot-grid tap construction is the recognized digital-assessment form, not freehand pencil drawing; 'a given number of equal faces' (cubes) remains identify-only. | — |

Locked by round3Gap.test.ts. | 08 Aug 2026 |

PARTIAL honestly: the line caps at 20, the standard's sums/differences clause reaches within 100. Locked by round3Gap.test.ts. | 08 Aug 2026 |
| measurement 2.MD.4 | PARTIAL | SELF-CORRECTION same day: the standard says MEASURE to determine how much longer — the new items hand the child both measurements, and the ruler widget measures ONE object, never two-and-compare in one flow.

| make-ten K.OA.3 | PARTIAL | Completeness audit: makeTenQ decomposes 10 (a + ❓ = 10, both orders, ten-frame build/visual) — a decomposition-pairs practice, but ONLY for the number 10; K.OA.3 wants numbers ≤10 decomposed MORE THAN ONE WAY. PARTIAL confirmed by reading makeTenQ in full | 08 Aug 2026 |
| multiplication 3.OA.1 | PARTIAL | Completeness audit: the 'a groups of b' interpretation lives in multiplicationQ's added-instead misconception feedback, the ≤6-addend repeated-addition steps, and word-problems' equal-groups items; interpret-products is not a distinct asked item form (division got one in Round 2, multiplication did not). PARTIAL confirmed | 08 Aug 2026 |
| volume 5.MD.3 | PARTIAL | Completeness audit: volumeQ's unit-cube fill items ('How many unit cubes fill a 3×4×2 box?') ground volume-as-cubic-units, but the definitional subs (3a unit cube / 3b n-cubes-means-n-units) are never asked directly. PARTIAL confirmed by reading volumeQ in full | 08 Aug 2026 |
| geometry 3.MD.9 | FULL | RENUMBERING BRIDGE (not a new verdict): this claim was verified FULL twice under its LEGACY code 3.MD.8 (31JUL2026 'perimeter FULL kept' + the apPerimQ/apCompareQ re-verification) before the 03AUG2026 Kansas-numbering migration renamed it 3.MD.9. The evidence is unchanged; this entry ties the new code to those verdicts so completeness checks pass without re-litigating | 08 Aug 2026 |
| word-problems 1.OA.2 | FULL | Round 4–5 gap build (08 Aug 2026): three-addend word problems, sum ≤ 20 — the standard's own shape, with a two-step worked solution; locked by round4Gap.test.ts. | 08 Aug 2026 |
| word-problems 2.MD.5 | FULL | Round 4–5 gap build (08 Aug 2026): one- and two-step LENGTH word problems within 100 in cm/meters — same-unit arithmetic on lengths, the standard's bound respected. | 08 Aug 2026 |
| word-problems 3.MD.3 | FULL | Round 4–5 gap build (08 Aug 2026): one-step mass/volume word problems in g/L, same units, add/subtract/multiply forms — the one-step bound is the standard's own. | 08 Aug 2026 |
| word-problems 4.OA.2 | FULL | Round 4–5 gap build (08 Aug 2026): multiplicative-comparison SOLVE problems ('k times as many' → k × base) with the additive misread seeded and NAMED — completes the 4.OA.1 reading items from Round 2. | 08 Aug 2026 |
| subtraction 1.NBT.6 | FULL | Round 4–5 gap build (08 Aug 2026): multiples-of-10 subtraction (10–90) with tens-thinking steps and the numberline visual (ladder-legal at L2); choices are multiples of 10 by construction. | 08 Aug 2026 |
| place-value K.NBT.1 | FULL | Round 4–5 gap build (08 Aug 2026): teens as ten-and-some-ones: base-10 rod+cubes picker (the standard's 'objects or drawings' AS the widget) + the 14 = 10 + ❓ recording form with a tenframe visual. | 08 Aug 2026 |
| shapes-basic K.G.1 | FULL | Round 4–5 gap build (08 Aug 2026): the position clause: above/below/beside on a two-row emoji scene, answer derived from the scene (test-derived, not canned); shape names were long dealt — both clauses now practiced. | 08 Aug 2026 |
| shapes-basic 1.G.1 | FULL | Round 4–5 gap build (08 Aug 2026): defining vs non-defining attributes: what is true of EVERY triangle/square/rectangle vs color/size/tilt; the test locks that color/size is never marked defining. | 08 Aug 2026 |
| counting 2.NBT.2 | PARTIAL | Round 4–5 gap build (08 Aug 2026): skip-count by 2s/5s/10s/100s from any start now dealt; the 'explain and generalize the patterns' clause is student production — PARTIAL is the cap. | 08 Aug 2026 |
| multiplication 5.NBT.2 | PARTIAL | Round 4–5 gap build (08 Aug 2026): n × 10/100/1000 items with the one-zero-per-power step stated; the 'explain patterns' clause (and the decimal-point half) keep this PARTIAL. | 08 Aug 2026 |
| multiplication 5.NBT.5 | PARTIAL | Round 4–5 gap build (08 Aug 2026): claim-check: L4–5 deal 2-digit × 2-digit with partial-products worked steps and numpad retrieval — real multi-digit fluency practice, but 3-digit-and-up factors are not dealt, so the standard's full multi-digit span caps at PARTIAL. | 08 Aug 2026 |
| data-graphs 2.MD.11 | PARTIAL | Round 4–5 gap build (08 Aug 2026): claim-check: the build-the-graph-row tap (Round F) constructs picture/bar-graph rows one icon per unit — construction at the tap register; a full from-scratch draw of both graph types is not dealt, and the solve-simple-problems clause is already covered by the reading items. | 08 Aug 2026 |
| sort-size 1.MD.1 | PARTIAL | Round 4–5 gap build (08 Aug 2026): claim-check: sortSizeQ orders three objects by size directly (the first clause); indirect comparison via a third object is not an item form — PARTIAL. | 08 Aug 2026 |
| addition 2.NBT.7 | PARTIAL | Round 4–5 gap build (08 Aug 2026): claim-check: addition/subtraction L4–5 compute within 1000 with carrying and worked steps; the 'concrete models or drawings' clause has no base-10 visual at that range — computation FULL-quality, models clause caps at PARTIAL. | 08 Aug 2026 |
| comprehension RL.K.1, RI.K.1, RL.1.1, RI.1.1 | ADD (grade-band build) | Early-reader (lvl<=2) comprehension items now narrate the FULL passage aloud before asking (speak override; previously only the question was spoken) — the story is read TO the child, satisfying the read-aloud framing of the K standards; app hints/worked-why are the prompting and support. PARTIAL only: these are ask-AND-answer standards and the ASK half has no surface (same wall as the RL/RI.2.1 verdict of 01AUG2026). | 09AUG2026 |
| comprehension RL.K.2, RL.1.2 | ADD (grade-band build) | PASSAGE_ELEMENTS adds what-happened-FIRST/LAST ordering and what-lesson questions on lvl-1/2 stories — the selection half of retell + central message. PARTIAL: retelling itself is child production a tap cannot perform. | 09AUG2026 |
| comprehension RL.K.3 | ADD (grade-band build) | FULL: the standard verb is IDENTIFY (characters, settings, major events) with prompting and support — who-is-this-story-about / where-does-it-happen / what-happened questions on read-aloud K stories are exactly that act. Locked by elaRound1.test.ts (who>=3, where>=3, order>=4 forms; all element targets lvl<=2). | 09AUG2026 |
| comprehension RL.1.3 | ADD (grade-band build) | PARTIAL: grade 1 raises the verb to DESCRIBE using key details — our items select rather than produce descriptions. | 09AUG2026 |
| comprehension RL.5.1, RI.5.1, RL.4.1, RI.4.1 | ADD/UPGRADE (grade-band build) | PASSAGE_EVIDENCE: 14 quote-accurately items on lvl-4/5 literary AND informational passages, explicit-statement and inference claims both dealt. The correct choice must be VERBATIM from the passage and one distractor is a near-miss misquote — choosing it is quoting inaccurately, the precise failure RL/RI.5.1 names. elaRound1.test.ts asserts verbatim/misquote/level/claim-mix mechanically. RL.4.1 PARTIAL->FULL (refer-to-details when explaining explicit + inferential now directly practiced); RI.4.1 newly mapped FULL. | 09AUG2026 |
| comprehension RL.5.2, RI.5.2 | ADD (grade-band build) | PASSAGE_SUMMARY: best-summary items on lvl-4/5 passages cover the summarize clause; theme questions already dealt on literary passages. PARTIAL both: RL.5.2 also spans drama and poem forms (not present); RI.5.2 requires TWO OR MORE main ideas and how details support them (single-main-idea items only). | 09AUG2026 |
| comprehension RL.K.5, RI.K.5, RL.K.6, RI.K.6 | ADD (Round 2 authored banks) | FULL x4 — each verb is literally the tap: RECOGNIZE text types (poem/storybook/informational examples all dealt, locked in elaRound2.test.ts); IDENTIFY front cover/back cover/title page (all three parts asserted present); NAME the author and illustrator from a mock cover byline AND DEFINE both roles (both clauses locked). Convention answers verified against an independent truth table in the test. | 09AUG2026 |
| comprehension RL.1.4 | ADD (Round 2 authored banks) | FULL: identify words/phrases that suggest feelings OR appeal to the senses — sensory items span hearing/touch/smell/sight in story sentences plus two feeling-phrase items (heart sank, bounced on her toes); both clauses locked in the test. | 09AUG2026 |
| comprehension RI.K.9, RI.1.9 | ADD (Round 2 authored banks) | FULL: TEXT_PAIRS presents two texts on the same topic and asks for basic similarities AND differences (both forms locked); K reachability locked (lvl<=2 pairs exist). | 09AUG2026 |
| comprehension RI.2.6 | ADD (Round 2 authored banks) | FULL: identify the main purpose incl. what the author wants to ANSWER, EXPLAIN or DESCRIBE — one item per named purpose, locked in the test. | 09AUG2026 |
| comprehension RL.1.5, RL.1.6, RI.1.5, RI.2.5, RI.2.9, RL.2.5, RL.K.9, RL.1.9 | ADD (Round 2 authored banks) | PARTIAL x8, each with the uncovered clause named: RL.1.5 selects the story-vs-fact-book difference but cannot EXPLAIN from a wide reading; RL.1.6 identifies the narrator at ONE point, not various points; RI.1.5/RI.2.5 know features but never LOCATE in a real text; RI.2.9 compares points but not specifically the MOST IMPORTANT points of two full texts; RL.2.5 beginning/ending roles only, not describing a whole structure; RL.K.9/RL.1.9 compare our OWN mini-story characters, not FAMILIAR stories. | 09AUG2026 |
| life-science K-ESS2-2, K-ESS3-1, K-ESS3-3, 1-LS1-1, 1-LS1-2, 2-LS4-1, 3-LS3-2, 3-LS4-2 | ADD (knowledge-support pass) | Knowledge-support pass: hand-authored bilingual DCI-knowledge items (see scienceKnowledge.test.ts — every claimed code has a deal-locked item plus spot-truth assertions). PARTIAL by construction: the PE verb (investigate/model/design/argue/observe/measure) is a performance a question bank cannot perform; only the disciplinary core idea underneath is practiced. | 09AUG2026 |
| physical-science 2-PS1-2, 2-PS1-3, 3-PS2-2, 4-PS3-1, 4-PS3-3, 4-PS4-1, 4-PS4-2, 5-PS1-2, 5-PS1-3, 5-PS1-4 | ADD (knowledge-support pass) | Knowledge-support pass: hand-authored bilingual DCI-knowledge items (see scienceKnowledge.test.ts — every claimed code has a deal-locked item plus spot-truth assertions). PARTIAL by construction: the PE verb (investigate/model/design/argue/observe/measure) is a performance a question bank cannot perform; only the disciplinary core idea underneath is practiced. | 09AUG2026 |
| earth-science K-ESS3-2, K-PS3-1, K-PS3-2, 1-ESS1-2, 2-ESS2-1, 2-ESS2-2, 3-ESS2-2, 3-LS4-1, 4-ESS2-2 | ADD (knowledge-support pass) | Knowledge-support pass: hand-authored bilingual DCI-knowledge items (see scienceKnowledge.test.ts — every claimed code has a deal-locked item plus spot-truth assertions). PARTIAL by construction: the PE verb (investigate/model/design/argue/observe/measure) is a performance a question bank cannot perform; only the disciplinary core idea underneath is practiced. | 09AUG2026 |
| comprehension RL.2.9 | ADD (Round 3) | FULL: compare and contrast two versions of the same story by different authors or from different cultures — five version-pairs built on faithful 1-2 sentence retellings of real widely-told variants (incl. a Chinese Cinderella pairing, the standard's own example class), with ALIKE and DIFFERENCE forms both locked in elaRound3.test.ts. | 09AUG2026 |
| comprehension RL.2.4 | EVIDENCE STRENGTHENED (Round 3) | Still PARTIAL, unchanged tier — repeated-lines and alliteration items now join poetry's rhyme items, but the DESCRIBE-how-they-supply-rhythm-and-meaning production clause remains selection-only. | 09AUG2026 |
| vocabulary RL.K.11, RI.K.11, RL.1.11, RI.1.11 | ADD (Round 3 grade-band) | PARTIAL x4: the leveled word bank carries genuine K-1 rows (jolly, damp, chilly, gentle, swift) dealt at level 1 with narration; the unknown-words half is practiced, the MULTIPLE-MEANING words-and-phrases clause has no surface (homophones are sound-alikes, not multiple-meaning words). | 09AUG2026 |
| antonyms RL.K.12, RI.K.12, RI.1.12 | ADD (Round 3 grade-band) | PARTIAL x3: same word-relationships evidence as the standing RL.1.12 PARTIAL (opposites over the 54-pair bank + matching, dealt at level 1; guidance = hints + narration); nuances-in-word-meanings clause uncovered. | 09AUG2026 |
| comprehension RL.K.1, RI.K.1 | UPGRADE PARTIAL->FULL (Round 4 construct mode) | The ask-half wall (standing since the 01AUG RL/RI.2.1 verdict) now has a surface: the child BUILDS a question about the just-heard story from scrambled word tiles (sentence widget) — producing, not selecting, a question about key details. The kindergarten wording is ask-and-answer WITH PROMPTING AND SUPPORT; the tile scaffold + full passage narration + hints are that support. Both halves now practiced. elaRound4.test.ts locks that every buildable question is grammatical, story-specific (shares content words with its passage), and K-leveled. The GRADE-1 codes (RL.1.1/RI.1.1) deliberately stay PARTIAL: no support clause in their wording, and our asking exists only in scaffolded tile form. | 09AUG2026 |
| comprehension RL.K.2 | UPGRADE PARTIAL->FULL (Round 4 construct mode) | Retell familiar stories, including key events, WITH PROMPTING AND SUPPORT: the child now RETELLS by ordering the story's events (order widget) — the picture-card retell used in real kindergarten assessment, in tile form, on a story just read aloud to them. The order is not editorial: each event carries a verbatim passage anchor and the test proves anchors ascend, so the retell order IS the story's order. RL.1.2 stays PARTIAL (no support clause; central message still selection-only). | 09AUG2026 |
| compare K.CC.6, 1.NBT.3 | UPGRADE PARTIAL->FULL (clause-closers) | K.CC.6: two emoji object groups, identify greater/fewer/equal — the exact verb; answers count-verified against the rendered groups in round5Clauses.test.ts. 1.NBT.3: two-digit comparisons now RECORDED with >, <, = (choose-the-symbol form), closing the symbol-recording clause the tier was held on; symbols recomputed independently in the test. | 09AUG2026 |
| place-value 4.NBT.2 | EVIDENCE STRENGTHENED (clause-closers) | Still PARTIAL, unchanged tier: the compare-with-symbols clause is now practiced (multi-digit choose-the-symbol at compare L3), but unit form remains unpracticed and the tier system is per-mapping, so the standard honestly stays PARTIAL. | 09AUG2026 |
| vocabulary RL.K.11, RI.K.11, RL.1.11, RI.1.11 | UPGRADE PARTIAL->FULL (clause-closers) | The multiple-meaning clause — the exact gap named in the Round 3 verdict — now has a surface: the MULTI bank asks for the OTHER meaning of bark/bat/ring/wave/trunk/light/park/letter, truth-table-locked. Unknown-words half was already practiced (K-1 vocab rows + context clues); the phrases component is practiced by the feeling-phrase items (heart sank, bounced on her toes). All three components now surfaced. | 09AUG2026 |
| shapes-basic K.G.6, 1.G.2 | ADD (ShapePick compose widget) | ShapePick compose widget (NEW): the prompt names a target shape and the child taps the PAIR of pieces that joins to make it — square from two diagonal-cut triangles (K.G.6's own printed example), rectangle from two squares, bigger triangle from two smaller, hexagon from two trapezoids, circle from two half-circles. Piece drawings are real geometry (SVG halves of the actual cut) and shapeCompose.test.ts locks every marked pair against an independent truth table. PARTIAL, deliberately: selecting the composing pair is the RECOGNITION half; physically placing pieces (drag-to-place) would earn FULL, and the wall verdict stands until that exists. 1.G.2 additionally spans THREE-dimensional composition (cubes, prisms, cones) and composing new shapes FROM composites — untouched, named. | 09AUG2026 |
| shapes-basic K.G.6 | UPGRADE PARTIAL->FULL (ShapeBuild tap-to-place) | Same-day upgrade over the ShapePick recognition claim: the NEW ShapeBuild widget has the child PLACE two pieces into the target's dashed outline — the composing act itself, on the standard's own example (two triangles joining full-sides-touching into a square). The halves are stored in composed coordinates so a placed piece draws into its true position, and shapeCompose.test.ts proves by shoelace area that the two halves EXACTLY tile the outline while no decoy can substitute (the tiling lock caught and forced a fix of two same-area decoys before ship). 1.G.2 stays PARTIAL (three-dimensional composition and composing-from-composites untouched); MO K.GM.C.10 stays PARTIAL on its explicit USING-MANIPULATIVES wording — a tap-place widget is a digital stand-in, and the tier honors the stricter reading. | 09AUG2026 |
| comprehension RL.1.6, RI.2.9 | UPGRADE PARTIAL->FULL (Round 9 clause-closers) | RL.1.6: the at-VARIOUS-POINTS clause (the exact hold in the Round 2 verdict) now has a surface — one shared dialogue passage with two who-is-speaking questions at two different points, locked in elaRound3.test.ts. RI.2.9: MOST-IMPORTANT-POINTS comparison of two texts now dealt in BOTH forms — the shared-point recycling pair (Round 2) plus a NEW differing-main-points pair; agree and differ forms both test-locked. | 09AUG2026 |
| comprehension RL.K.7, RI.K.7, RI.1.6, RL.1.7, RI.1.7 | ADD (Round 10 picture-and-text) | The illustration wall gets a surface: an emoji scene stands as the illustration beside the text (PICTURE:/TEXT: passages). RL.K.7/RI.K.7 FULL — with prompting and support, describe (by selection) what moment/idea the illustration depicts, mirroring the RL.K.1 with-support precedent; narration + hints are the support. RI.1.6 FULL — DISTINGUISH picture-facts from word-facts is exactly the which-fact-comes-from-the-PICTURE item. RL.1.7/RI.1.7 PARTIAL — grade 1 drops the support clause and asks the child to USE illustrations to DESCRIBE characters/setting/ideas; our items select a description (the when-does-it-happen item is the setting component). Honest ceiling: emoji scenes are minimal illustrations; richer art would strengthen but not change the verbs practiced. | 09AUG2026 |
| comprehension RI.1.5, RI.2.5 | UPGRADE PARTIAL->FULL (Round 10b feature-locate) | The never-used-to-LOCATE clause closes: a rendered mini fact-book page (title, two headings, caption, glossary) IS the passage, and the questions require retrieving facts THROUGH its features — what the caption says, which heading holds a topic, where a word is defined. Know-and-use both practiced on one real page; the Round 2 index/table-of-contents/bold items cover the remaining named feature types. | 09AUG2026 |
| animals-nature 3-LS2-1 | REMOVED (completeness audit) | REMOVED. The claim asserted that animals form GROUPS that help members survive. The animals-nature bank does contain group-living content ("Where do bees live together? → In a hive"), so the earlier note here — that no group item existed and that the only group items were classification — was wrong and is corrected. The real reason the claim cannot stand: establishing that bees live in a hive is not the standard. 3-LS2-1 asks the child to CONSTRUCT AN ARGUMENT that forming groups helps members survive, and no item asks for or scores that reasoning. Removed as an unearned claim, not as an absent topic. | 09AUG2026 |
| animals-nature K-LS1-1, 1-LS3-1, 3-LS1-1, 3-LS4-3, 4-LS1-1 | PASS (completeness audit) | Bank read: what-plants-need, baby-animal and tadpole/caterpillar life-cycle items, where-polar-bears/fish-live habitat items, gills/feathers/trunk/roots structure-function items — each PARTIAL earned as DCI knowledge under its PE. | 09AUG2026 |
| human-body 4-LS1-1, 4-LS1-2 | PASS (completeness audit) | Organ- and senses-items support the structures and information-processing DCIs; PARTIAL correct (performance verbs remain walls). | 09AUG2026 |
| vocabulary RL.K.11, RI.K.11, RL.1.11, RI.1.11 | DOWNGRADE FULL->PARTIAL (independent adversarial audit) | The audit applied the crosswalk's own per-mapping rule (stated the same day in the 4.NBT.2 verdict) against these claims: the AND-PHRASES clause was earned via feeling-phrase items that live in the comprehension generator, not vocabularyQ — cross-skill evidence cannot make this mapping FULL. Unknown-words and multiple-meaning-words clauses remain genuinely practiced in-mapping; the phrases clause is the named gap. | 09AUG2026 |
| vocabulary RL.K.11, RI.K.11, RL.1.11, RI.1.11 | RE-EARNED FULL (built to the adversarial audit's spec) | The AND-PHRASES clause is now earned INSIDE this mapping: a six-item PHRASES bank (in a flash, lend a hand, keep an eye on, under the weather, all ears, hand in hand) deals through vocabularyQ itself with bilingual meanings — the per-mapping rule the audit enforced is now satisfied without borrowed evidence. | 09AUG2026 |
| (self-audit — corrective pass) 3-LS2-1, RL.K.11, RI.K.11, RL.1.11, RI.1.11 | CORRECTIONS APPLIED (adversarial review of our own corrective text) | On 10 Aug 2026 the corrective prose written on 09–10 Aug was itself put to refute-first review, and six published statements failed. (1) The report asserted Kansas 'publishes no Pre-K standards to map against' — FALSE; Kansas publishes the Kansas Early Learning Standards (KELS). The claim had been inferred from the absence of Pre-K codes in THIS file — a fact about our data restated as a fact about the state. (2) It asserted the Pre-K skills have 'no state code to cite' — FALSE; 14 of the 17 Pre-K-flagged skills carry a Kansas claim, and the page now computes that figure. (3) The hand-written Pre-K skill list named 8 of 17; it is now generated from the catalog. (4) The release badge read 'INDEPENDENTLY AUDITED' while the footer disclaimed independent certification, and the reviewers were AI agents run by this project; the badge now reads 'ADVERSARIALLY SELF-REVIEWED'. (5) The 31 Jul audit tally mixed three rounds together and is now stated per round. (6) The 3-LS2-1 removal rationale claimed no supporting item existed anywhere in the app; the animals-nature bank does contain group-living items, and the defensible reason is narrower — no item asks the child to CONSTRUCT AN ARGUMENT that grouping aids survival. No coverage number changed as a result of any of these; every one was a wording or provenance defect. | 10AUG2026 |
| comprehension (informational text: main topic, retell, author's reasons) RI.K.2, RI.1.2, RI.K.8, RI.1.8 | 4 ADD FULL (built + verified this pass) | The RI strand was thin because the passage bank was almost entirely STORIES. Seven informational passages were authored: four sequenced (so 'retell key details' has a real surface, not just detail-spotting) and three opinion pieces that state a point and then give reasons. Two locks make these defensible rather than asserted: every 'reason the author gives' is checked against the passage's own words, and every retell's anchors must appear in the passage in ascending order. Distractors are checked for ABSENCE, so a child can never pick a true-but-unstated option and be marked right for the wrong reason. All four surfaces were deal-verified in 1,500 real sessions before the claims were written. HONEST BOUND: the informational extras are matched to ENGLISH passages only (the es-mode bank is separate and was not extended this pass) - acceptable here because these are English-language ELA standards, but it means a Spanish-mode child does not meet them. | 15AUG2026 |
| content review (all 15 Aug 2026 passages + questions) | HUMAN-REVIEWED AND APPROVED | HUMAN REVIEW — 15 Aug 2026. Craig Watson read every passage and question added on 15 Aug 2026 (34 passages: 7 English informational/opinion, 27 Spanish across two rounds; plus 43 attached questions) and approved them for children. This closes the review half of the published provenance claim, 'authored under human direction and human-reviewed'. The review document was generated directly from app/src/lib/content.ts, so what was read is exactly what ships. Drafting was assisted; approval was a person's. | 15AUG2026 |
| — | — | 🔬 Build-the-model interaction mode (ModelBuild widget + models.ts). Four authored models upgrade the four "develop/use a model" PEs they serve from PARTIAL to FULL — the first FULL science verdicts in either state, which were 0 before today. Each model is bound to the skill its standard is mapped to, and to that skill’s band: K-ESS3-1/K.ESS3.A.1 moved OFF life-science (Grade 3) onto animals-nature (DK-2, grade 0), because a kindergarten standard claimed on a Grade-3 surface is a mismatch a reviewer would rightly flag. Answers re-derived from an independent truth table in modelTruth.test.ts; dealing and the skill binding locked in modelDeal.test.ts. NOT claimed: the other four/five model PEs (waves, landforms, particles, geosphere interactions, MO life cycles) have no authored model yet, and every non-model science PE stays exactly as it was. | 2026-08-17 |
| — | — | 🔬 Model round 2: five more authored models (land-water-map, wave-pattern, spheres, particles, two-life-cycles) close every remaining "develop a model" PE that a placement+direction model can honestly serve. Grade-band rule applied again: the grade-2 map standard moved OFF earth-science (Grade 4) onto animals-nature (DK-2). MO 4.PS4.A.1 boundary ("the terms amplitude and wavelength should not be assessed") is respected mechanically — a test asserts neither term appears in any child-facing string, either language. The particles model’s tray carries the "air is empty" misconception as a distractor, per MO’s own clarification evidence (adding air to a ball). Truth-table re-derivation and skill-binding tests extended to all nine models. | 2026-08-17 |
| — | — | 🖐️ ShapeDrag drag-manipulative (v2.39.0): free pointer drag with tap fallback. KS 1.G.2 -> FULL (composite pieces close composing-from-composites; the two-cube prism closes 3D in the pictorial register — the drawn rear cube piece is its VISIBLE region because the shoelace tiling test rejected overlapping hexagons). MO K.GM.C.10 -> FULL on the virtual-manipulative reading, stated openly: MO does not say "physical", and a piece the child picks up, moves and releases is a virtual manipulative in the standard instructional sense; the earlier verdict honored the stricter reading when the interaction was tap-only. MO 1.GM.A.2 -> FULL (compose + hands-on decompose + part-whole question). ALSO FIXED IN THIS PASS, found by the new all-skill paper sweep: the compose branch dealt widget items in PLAIN mode with no gate, and the worksheet filter named neither the fields nor the pair:/build: sentinels — since 09 Aug a printed worksheet could carry "A) pair:sq-diag B) pair:x". The branch is now plain-gated, the filter is a single exported source of truth, and paperSafety.test.ts sweeps all 80 skills. | 2026-08-17 |
| — | — | 🎯 Fraction number line (NumberLine widget, v2.40.0): the drag primitive applied to the 3.NF cluster. Three modes mirror the standards' own language — partition (the child splits the whole), place (mark off a lengths of 1/b), equiv (same point IS equivalence, pairs verified by cross-multiplication in numberLineTruth.test.ts). MO describe-clauses carried by post-placement asks about the line just built. Tolerance (0.4/den) proven to never accept a neighbouring tick. KS 3.NF.3b claimed PARTIAL only — the child sees and hears why pairs are equivalent but does not generate pairs. Every tick is a real button, so the task is fully operable without dragging. | 2026-08-17 |
| — | — | 🧊 VolumePack (v2.41.0): the packing act of 5.MD.3/5. The child packs unit cubes one by one (painter-order isometric render); an underpacked solid CANNOT be scored (Check gates on full), overpacking is impossible, and the volume + multiplication claims are answered about the solid just packed. volumePackTruth.test.ts recomputes every capacity, marked answer and marked multiplication from the dims, and proves no distractor accidentally equals the volume. Real-DOM test proves underpack-blocked / wrong-claim-wrong / remove-works. KS 5.MD.3, 3a, 3b, 5, 5a, 5c → FULL; MO 5.GM.B.4a → FULL. NOT claimed: 5.MD.5b stays as it was (formula application, already FULL via the existing bank); MO 5.GM.B.4b/5 already FULL. | 2026-08-17 |
| — | — | 🔟 BundleBuild (v2.42.0): base-ten composing as an act. Check accepts ANY composition worth the target (flexibility natively); secondWay items refuse the same triple and require a genuinely different composition — proven winnable by exhaustive search within the widget’s own limits (h≤9, t≤20, o≤30). The bundle/break exchanges (10 ones ⇄ 1 ten, 10 tens ⇄ 1 hundred) are 2a/1a’s "bundle of ten ones/tens" understanding as an interaction. KS 1.NBT.2 + a–d and 2.NBT.1a–c → FULL. MO: no equivalent NC codes remained (the MO base-ten GLEs were closed in earlier rounds); nothing claimed. | 2026-08-17 |
| — | — | 🍕💯➗🔟📏🧱⏱️🔺🧮 The DO-THEM-ALL round (v2.44.0). Batch A — procedural generators with COMPUTED answers for the 4.NF/5.NF operations cluster, deep decimals (expanded/unit form to thousandths, comparisons incl. the ≠ statement), and 5.NBT.6 long division; locked by harvest-and-recompute over ~15,000 dealt items (fracOpsTruth.test.ts). Batch B — BundleBuild addition mode (build, bank, ADD, bundle when ones pile past ten; the 47+5 regroup act locked in the real DOM), UnitLay measure-twice (units divide the object exactly), ArrayBuild area arrangements (factor pairs, rotations refused), three new number-line items (whole-as-fraction, same-den and same-num comparisons), and the K.CC.4b/4c/4d counting-understanding items (incl. count-and-TYPE with 0 as a real count). Batch C — time-interval estimation (wrong choices ≥3× off) and Euler-checked prism/pyramid properties. Honest PARTIALs: K.CC.4a (say-aloud clause needs speech), 5.NF.5b (explain-why needs production). | 2026-08-18 |
| — | — | 🖼️ The illustration round (v2.45.0): the RL/RI x.7 codes were walls only because questions could not show art — the app now owns 20 commissioned illustrations and 11 labeled diagrams, so a new img visual kind (REQUIRED bilingual alt text) puts real art in questions. AUTHORING RULE, absolute: every claim about an illustration states only what was verified BY LOOKING — six creature images were rendered and read before authoring, and illusTruth.test.ts restates the visible facts independently (bundle-on-back, coin-in-beak, equal pie slices, mid-leap pose, reading glasses, curling tentacles) and checks every marked answer against them; diagram items are checked against Diagram.tsx’s own drawn labels. MO K vocabulary: picture-category sorts (memberships checked against an independent table) and rendered picture-dictionary pages (pairings harvest-verified in both languages). Deal rates kept LOW (1-in-7 comprehension) — the register-crowding flakiness lesson is one day old. | 2026-08-18 |
| — | — | 🪙💯✏️🧠 The last-mile round (v2.46.0): the final honest claims before the speech/drawing frontier. Counters gives K.OA.1 its with-objects representation as an act (real-DOM locked, subtraction as take-away). HundredChart continues the count by ones and tens with a growth-pattern ask — PARTIAL, the oral clause named. TraceCanvas shape glyphs serve K.G.5’s drawing clause — PARTIAL, sticks-and-clay named. Five explain/justify/rule codes move NC → PARTIAL via justification-SELECTION items (the true reason among real misconceptions; rule answers recomputed against their own sequences) — every verdict states that selection is not production. After this round, every remaining gap in every subject requires the child to SPEAK, DRAW FREELY, or WRITE — the input-mode frontier, recorded as product bets, not build rounds. | 2026-08-18 |
| — | — | Freehand-draw + build-a-graph registers shipped (DrawShape widget, TapConstruct bar/pict skins). K.G.5, 2.MD.11, 1.MD.4 re-judged FULL on construction evidence. Speech register (SpeechCheck) shipped as additive practice — NO tier rides on it until verified on a real child voice on the real iPad. | 18AUG2026 |
| — | — | 4.MD.4 re-judged FULL: eighth-inch line-plot builds + fraction-subtraction solve items close both named clauses. Free-draw partition (scoreDrawCutStrip/Circle, drawCutTruth-locked) added as depth evidence on the already-FULL partition standards (1.G.3/2.G.3 and MO twins) — no tier change from it. | 18AUG2026 |
| — | — | Reachable-frontier round: 28 ELA placeholder rows ('Begins in…', 'Not applicable…') flagged notApplicable (shown, not counted — the framework itself defers them). New selection-honest banks: listen-first comprehension (RL.K.13 FULL + 11 x.13 PARTIALs, text-complexity gap named), context clues (RI.2.4 FULL + 8 x.4 PARTIALs, ask/domain/figurative gaps named), design-test data analysis (K-2-ETS1-3 FULL + 3 PARTIALs, hands-on walls named), source-based conclusions (5 HGSS x.2 PARTIALs). Every FULL claims only identify/determine/analyze-given-data verbs; every PARTIAL names its uncovered clause. | 19AUG2026 |
| — | — | Round A mapping sweep (KS, 19 Aug 2026 PM): word-relationship codes (x.12) FULL via synonyms/antonyms/analogies at 2-3, PARTIAL at 4-5 (figurative clause named); language-conventions x.10 codes PARTIAL via grammar; RI.5.4/SL academic-word codes PARTIAL; firsthand/secondhand + text-features + answer-from-provided-sources + complex-text codes PARTIAL via comprehension with gaps named. Verb discipline as MO Round A. | 19AUG2026 |
| — | — | Rounds B+D (KS, 19 Aug 2026 PM): character/theme/structure/persuasion recognition banks (ELAB_ITEMS) → 14 ELA codes with production clauses named (RL.5.3 and RI.5.5 FULL on their compare verbs); science claims/define/merit items → 6 PE PARTIALs. Same verb discipline as every prior round. | 19AUG2026 |
| — | — | Round E (KS): theme/genre compare codes + relationship codes PARTIAL via the paired-story and structure banks; 4-PS4-3 PARTIAL via the pattern-signal items. | 19AUG2026 |
| — | — | PARTIAL re-audit (math): the 39 KS math PARTIALs predated both the note discipline and 15 interaction modes. Ten upgraded to FULL against verified current evidence (K.CC.1 via the hundred chart + count-aloud, K.CC.3 numeral typing, K.CC.4/4a via Counters, 2.MD.6 number-line representation, 3.OA.1 groups+ArrayBuild, 3.NF.3b same-point equivalence, K.G.4 solids+rotated-shape compare, 3.G.1 shared-attribute truths, 5.MD.2 after adding the 1/16 plot scale). The remaining 29 now carry explicit gap notes — most gaps are explain/flexible-strategy/child-drawn-representation clauses, plus a few missing item forms (length estimation, thousandths, 2-digit area model) that are honest future work, not walls. | 21AUG2026 |
| — | — | Five-forms build (21 Aug 2026): the item forms the PARTIAL re-audit recorded as honest future work are now built and truth-locked (lengthEstimateQ, thousandthsQ, the areamodel figure, unitFormQ, tenTimesDivQ) — 2.MD.3, 5.NBT.3, 4.NBT.5, 4.NBT.2, 4.NBT.1 upgraded to FULL on dealt evidence. | 21AUG2026 |
| — | — | 3.MD.1 time skill upgraded: minute-level clock reading and arbitrary-minute elapsed arithmetic built (six-forms pass, sixFormsTruth-tested). | 21AUG2026 |
| — | — | ELA PARTIAL re-audit (21 Aug) — the 53 never-noted KS ELA PARTIALs individually re-read. 21 upgraded: QuestionMaker performs the ASK clause of the ask-and-answer standards; LetterTiles spelling is the ENCODING clause of RF phonics (KS statements carry no read-aloud clause); the vocabulary strategy suite (context clues, affixes, wordMachines Latin/Greek, dictionary skills) covers the determine-or-clarify family; figurative+analogies close the grade 4-5 nuance codes; the revise/add-details widgets perform W.4.5's with-guidance revision. Conventions-when-WRITING codes stay walls (consistent with the settled MO edit-for-conventions rationale) with the recognition register noted. Two new buildable forms: shades-of-meaning, per-paragraph focus. | 21AUG2026 |
| — | — | ELA seven-forms build: shades-of-meaning and per-paragraph-focus banks close RL.2.12 and RI.2.2 (elaSevenForms-tested). | 21AUG2026 |
| — | — | Reverse capability sweep, science: the represent-data clauses (3-ESS2-1, 5-ESS1-2, 5-ESS2-2) were tiered before the graph-BUILD register existed (18 Aug) — SCI_GRAPHS now performs them; 3 upgraded. K-2-ETS1-2 mapped NC→PARTIAL via the new SHAPE_FUNC bank. | 21AUG2026 |
| — | — | HUMAN REVIEW — 21 Aug 2026. Craig Watson reviewed and approved the 175-item Content Review Pack covering everything child-facing added 15–20 Aug 2026 (the Rounds A–F banks: grade-5 reading responses, edit-for-conventions, listening stories, media literacy, MO social-studies waves, sound play, ELAB comprehension, design/data items, and the rest of the frontier-round content). Approved for children as written. The pack was generated directly from app/src/lib/content.ts, so what was read is exactly what ships. Drafting was assisted; approval was a person's. Authored items added 21 Aug (ELA seven-forms, science represent/shape-function banks — 46 items) are queued in the NEXT incremental pack and remain machine-verified but human-review-pending until it is approved. | 21AUG2026 |
| — | — | HUMAN REVIEW — 21 Aug 2026 (second pass, same day). Craig Watson reviewed and approved the 46-item incremental Content Review Pack (docs/internal/Content_Review_Pack_21AUG2026.html): the ELA seven-forms banks (predict-next, r-controlled vowels, inflectional endings, topic-vs-main-idea, fragment/run-on repair, shades of meaning), the science represent-the-data builds and shape-function items, and the flag-as-symbol US-symbols item — English and Spanish both. Approved for children as written. With this, EVERY authored child-facing item in the app is human-reviewed; nothing ships review-pending. Extracted directly from app/src/lib/content.ts; drafting was assisted, approval was a person's. | 21AUG2026 |
