🌰 AcornSmarts × Missouri Standards — Curriculum Alignment Report

Missouri writes fine-grained Grade-Level Expectations, and this report's claim unit is the LETTERED row wherever DESE publishes no parent row — which yields 220 K–5 mathematics claim units. That is our stated granularity, not a count DESE itself prints. (An earlier build of this report rolled lettered sub-items up to a parent unconditionally and reported a 189 denominator. That was wrong: it silently dropped 31 real Missouri expectations, and it was corrected on 06 Aug 2026. The 189 figure should not be quoted.) FULL means the app's evidenced items exercise the expectation as written; PARTIAL means a clause — physical materials, free-form production, justification or discourse — is beyond what a tap-based practice app honestly does, and the verification log names which clause.

Missouri folds reading, writing, speaking/listening and language into one ELA document, and its expectations are lettered items (e.g. 2.R.1.B.a). The claim unit differs by document, and each section states its own: 660 of the 661 K–5 ELA codes and all 256 social-studies codes carry that trailing letter, so there the letter is the claim unit; only 31 of the 220 mathematics expectations do (e.g. 2.RA.B.2a) and none of the 89 science performance expectations do, so those two sections claim at the code DESE publishes. A question-based practice app claims only the checkable word-, sentence- and short-passage-level items; whole categories (writing production, speaking and listening, research) are out of scope by design and are listed NOT COVERED.
