MCAS Math Grade 3 study guide
MCAS Math Grade 3 · Work through your exam, one topic at a time.
The Grade 3 Mathematics MCAS is part of the Massachusetts Comprehensive Assessment System, a set of statewide standardized tests administered by the Massachusetts Department of Elementary and Secondary Education (DESE). Under state policy described by DESE, students in grades 3–8 and 10 take MCAS tests in English language arts and mathematics, so the Grade 3 mathematics test is the first mathematics MCAS a student encounters. The MCAS Math Grade 3 study guide has 5 sections and about 1,451 words.
01Operations and Algebraic Thinking
This domain tests how well you use multiplication and division to solve problems and see patterns in numbers. Grade 3 work stays within 100, but the thinking is the foundation for later math: equal groups, arrays, unknown values, and the rules that connect the two operations.
334 words, about 2 min02Number and Operations in Base Ten
This domain tests place value through the thousands and flexible adding and subtracting within 1,000. You need to read and write numbers in standard, expanded, and word form, round to the nearest 10 or 100, and add or subtract with regrouping.
284 words, about 1 min03Number and Operations-Fractions
This domain introduces fractions as numbers, not just shaded pieces of a picture. You should name unit fractions, place fractions on a number line, recognize simple equivalent fractions, and compare two fractions with the same numerator or the same denominator.
274 words, about 1 min04Measurement and Data
This domain covers telling time, measuring and estimating length, reading scaled graphs, and understanding area and perimeter. Grade 3 measurement connects directly to multiplication: area is the number of unit squares that cover a shape.
296 words, about 1 min05Geometry
This domain is about shape attributes and equal parts. You should identify quadrilaterals by their properties - parallel sides, right angles, equal sides - and partition shapes into parts with equal areas, naming each part as a unit fraction.
