What the test measures

Number and Operations—Fractions skills

Grade 3: unit fractions, fraction notation, number-line representations, compare fractions
Grade 4: equivalence, fraction building, multiply fraction by whole number, decimals to hundredths
Grade 5: equivalent fractions, addition/subtraction, fraction multiplication/division, fraction as division

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.
