Montana’s MAST is a state-specific through-year assessment built by New Meridian and aligned to Montana’s academic content standards, not a Smarter Balanced-style claims/targets framework. The math blueprints organize content into grade-level strands/testlets that map directly to CCSS-M-derived Montana standards.
MAST Grade 3 math practice. Domain by domain.
MAST Grade 3 math practice organized by the test's 7 official reporting domains. Together they connect 9 playable math skills to Montana PK-12 Mathematics Content Standards / Common Core State Standards for Mathematics (CCSS-M)-aligned Montana standards.
Reporting categories
MAST Grade 3 reporting domains
Multiply and Divide Within 100Students use the associative, commutative, and distributive properties to multiply and divide within 10×10 and complete facts fluently.8 QsPractice →Real-World Problems and PatternsStudents solve two-step real-world problems and explain arithmetic patterns associated with multiplication using properties of operations.8 QsPractice →Place Value and Operations in Base TenStudents add and subtract within 1,000 and multiply a two-digit multiple of 10 by a one-digit whole number.8 QsPractice →Unit Squares and Square UnitsStudents understand area as the measure of a two-dimensional region and find rectangle area by counting unit squares and multiplying side lengths.8 QsPractice →Solve Area ProblemsStudents solve real-world and mathematical area problems and use area models to explain the distributive property of multiplication over addition.8 QsPractice →Data and GraphingStudents use multiplication skills with scaled categorical data displays and line plots to solve problems.8 QsPractice →Two-Dimensional Geometric FiguresStudents classify shapes by shared attributes, focusing on quadrilaterals, and solve perimeter problems.8 QsPractice →

How the MAST structures Grade 3 math
The blueprint publishes a through-year design of 12 strands/testlets per grade, with 1 strand per testlet, 2 reporting attributes per strand, and 9–13 items per testlet. It also specifies approximate item-type and DOK distributions, but does not publish percentage weighting by domain in the captured blueprint text.
