Two-Step Word Problems and Patterns: Grade 3 Math Test Answer Key – PDF Download

Grade 3 Two Test Answer Key: questions 1–5

Question 1: Find the unknown (2 points)

1. \(n = 75 – 38 = 37\). \(n = 37\)
2. \(k = 63 : 9 = 7\). \(k = 7\)

Scoring: 1 point for each correct value.

Question 2: Marbles in bags (3 points)

1. \(m = 5 \times 6 + 4\)
2. \(5 \times 6 = 30\), then \(30 + 4 = 34\). \(m = 34\)
3. \(34 – 9 = 25\). Priya has 25 marbles.

Scoring: 1 point for a correct equation. 1 point for 34. 1 point for 25.

Question 3: Estimate by rounding (2 points)

1. 473 rounds to 500 and 286 rounds to 300. \(500 + 300 = 800\). The estimate is 800.
2. \(473 + 286 = 759\). It is reasonable because 759 is close to 800.

Scoring: 1 point for 800. 1 point for 759 and a correct reason.

Question 4: Complete the pattern (2 points)

1. \(24 + 8 = 32\) and \(32 + 8 = 40\). The missing numbers are 32 and 40.
2. The rule is add 8.

Scoring: 1 point for both numbers. 1 point for the rule.

Question 5: Multiplication table pattern (2 points)

1. \(3 \times 5 = 15\) and \(6 \times 4 = 24\). The missing products are 15 and 24.
2. Each number in the 6s row is double the number above it. This happens because \(6 = 3 + 3\), so \(6 \times c = 3 \times c + 3 \times c\).

Scoring: 1 point for both products. 1 point for double with a reason.

Grade 3 Two Test Answer Key: questions 6–9

Question 6: Change at the store (2 points)

1. \(c = 20 – (4 \times 3 + 5)\)
2. \(4 \times 3 = 12\), \(12 + 5 = 17\), \(20 – 17 = 3\). Ethan gets $3 in change.

Scoring: 1 point for a correct equation. 1 point for $3.

Question 7: Sharing stickers (3 points)

1. \(s = (24 + 18) : 6\)
2. \(24 + 18 = 42\), then \(42 : 6 = 7\). \(s = 7\)
3. \(7 – 3 = 4\). Each friend has 4 stickers.

Scoring: 1 point for a correct equation (parentheses needed). 1 point for 7. 1 point for 4.

Question 8: Order of operations (2 points)

1. \(2 \times 6 = 12\), then \(7 + 12 = 19\). The value is 19.
2. \(7 + 2 = 9\), then \(9 \times 6 = 54\). The value is 54.

Scoring: 1 point for each correct value.

Question 9: Pages left (2 points)

1. \(p = 96 – (28 + 35)\)
2. \(28 + 35 = 63\), then \(96 – 63 = 33\). 33 pages are left.

Scoring: 1 point for a correct equation. 1 point for 33.
