What the test measures

Number and Operations—Fractions skills

Extend understanding of fraction equivalence and ordering
Build fractions from unit fractions
Use equivalent fractions as a strategy to add and subtract fractions
Apply and extend previous understandings of multiplication and division to fractions

Standards basis

Massachusetts Curriculum Frameworks / Massachusetts learning standards (CCSS-aligned math standards as adopted by Massachusetts) — Massachusetts

How the MCAS reports it

MCAS is Massachusetts’ statewide assessment program, and its math design is built on Massachusetts Curriculum Frameworks rather than a separate multi-state framework. The official MCAS pages state that MCAS assessments are based on the state’s learning standards and that the math tests are organized by Massachusetts grade-band domains/reporting categories.

Blueprint & weighting

The official MCAS math blueprint/test-design materials were not successfully retrievable in this session, so published domain weightings could not be verified from a primary PDF/page.
