Sample Montana MAST Grade 3 Mathematics Practice Questions

Try these sample questions to test your Montana MAST Grade 3 Mathematics exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Mrs. Green places 5 apples in each of 4 gift baskets. How many apples are there in all?
A.20
B.9
C.25
D.16
Explanation: Equal groups are multiplied: 4 baskets with 5 apples each gives 4 × 5 = 20 apples. Multiplication counts the total when each group has the same number of items.
2Leo has 18 cookies to share equally among 3 friends. How many cookies does each friend get?
A.6
B.5
C.15
D.21
Explanation: Equal sharing is modeled by division: 18 ÷ 3 = 6 cookies per friend. Each friend receives one-third of the total.
3Which equation shows the commutative property of multiplication?
A.6 × 4 = 4 × 6
B.6 × 1 = 6
C.6 + 4 = 4 + 6
D.6 × (4 + 1) = (6 × 4) + (6 × 1)
Explanation: The commutative property of multiplication says that changing the order of the factors does not change the product, so 6 × 4 = 4 × 6 = 24. The factors stay the same but swap positions.
4A bookshelf has 7 shelves with 6 books on each shelf. How many books are on the bookshelf in all?
A.42
B.13
C.48
D.36
Explanation: Each of the 7 shelves has 6 books, so the total is 7 × 6 = 42 books. This is an equal-groups multiplication situation.
5Maria has 24 stickers. She puts 6 stickers on each page of her album. How many pages does she fill?
A.4
B.6
C.18
D.30
Explanation: Finding the number of equal groups is division: 24 ÷ 6 = 4 pages. Each page holds 6 stickers, so 24 stickers fill 4 pages.
6An array has 3 rows with 7 squares in each row. Which expression gives the total number of squares?
A.3 × 7
B.3 + 7
C.21 ÷ 3
D.7 - 3
Explanation: An array of 3 rows with 7 squares in each row is an equal-groups situation, so the total is 3 × 7 = 21 squares. The number of rows times the number in each row gives the total.
7Raffle tickets cost USD 3 each. How much do 8 tickets cost?
A.USD 24
B.USD 11
C.USD 32
D.USD 21
Explanation: Each ticket costs USD 3, so 8 tickets cost 8 × 3 = 24 dollars, or USD 24. Money totals in equal groups are found by multiplication.
832 students sit at tables with 8 students at each table. How many tables are needed?
A.4
B.8
C.24
D.40
Explanation: Finding the number of equal groups is division: 32 ÷ 8 = 4 tables. Eight students per table means 32 students fill 4 tables.
9A farm has 9 pens, each with 6 sheep. How many sheep are on the farm in all?
A.54
B.15
C.63
D.48
Explanation: Each of the 9 pens has 6 sheep, so the total is 9 × 6 = 54 sheep. Equal groups are combined by multiplication.
10Which expression is equal to (3 × 4) × 5 by the associative property of multiplication?
A.3 × (4 × 5)
B.3 + 4 + 5
C.3 × 4 + 5
D.(3 + 4) × 5
Explanation: The associative property of multiplication says that grouping factors differently does not change the product, so (3 × 4) × 5 = 3 × (4 × 5) = 60. Only the parentheses move; the order of factors stays the same.

Operations & Algebraic Thinking

Interpretation of products and quotients of whole numbers using equal groups and arrays, fluency multiplying and dividing within 100, properties of operations (commutative, associative, distributive), multiplication and division within 100, two-step word problems using all four operations, and identifying and explaining arithmetic patterns.

18%

Number & Operations in Base Ten

Use place value understanding to round whole numbers to the nearest 10 or 100, fluently add and subtract within 1,000, and multiply one-digit whole numbers by multiples of 10 (10–90).

22%

Number & Operations — Fractions

Understand a unit fraction as one part of b equal parts, represent fractions on a number line, recognize and generate simple equivalent fractions, express whole numbers as fractions, and compare two fractions with the same numerator or same denominator.

25%

Measurement & Data

Tell and write time to the nearest minute, calculate elapsed time, measure and estimate liquid volume (liters) and mass (grams, kilograms), solve one-step word problems involving measurement, draw and interpret scaled picture and bar graphs, generate measurement data with rulers (halves and fourths of an inch), area as tiling unit squares and A = l × w, perimeter of polygons, and area of rectilinear figures.

Montana MAST Grade 3 Mathematics Study Tips from Top Performers

1Practice basic multiplication facts (0 to 10) daily to build the fluency within 100 that MAST Grade 3 items rely on.
2Break two-step word problems into Step 1 and Step 2 before choosing an answer, and label the units (apples, dollars, minutes) for each step.
3Use number line diagrams when working with fractions to clearly see distance from 0 and compare fraction sizes by the denominator.
4Remember area is measured in square units ($A = l \times w$ for rectangles) while perimeter is the distance around the outer edge ($P = 2l + 2w$).
5Verify addition and subtraction within 1,000 using inverse operations — check subtraction with addition — and practice rounding to the nearest 10 and 100.
