Grade 3 Division Test Answer Key: questions 1–5
Question 1: Sharing equally (2 points)
- \(18 : 3 = 6\).
- 6 berries are on each plate.
Scoring: (a) 1 point for the sentence. (b) 1 point for 6.
Question 2: Making groups (2 points)
- 5 jumps of 4 reach 20, so she fills 5 cups.
- \(20 : 4 = 5\).
Scoring: (a) 1 point. (b) 1 point.
Question 3: Fact family (2 points)
- \(7 \times 8 = 56\) and \(8 \times 7 = 56\).
- \(56 : 7 = 8\) and \(56 : 8 = 7\).
Scoring: (a) 1 point for both facts. (b) 1 point for both facts.
Question 4: Unknown factor (2 points)
- \(42 : 6 = 7\), so \(n = 7\).
- \(64 : 8 = 8\), so \(n = 8\).
Scoring: (a) 1 point. (b) 1 point.
Question 5: Unknown in division (2 points)
- \(4 \times n = 36\), so \(n = 9\).
- \(5 \times 7 = 35\), so \(m = 35\).
Scoring: (a) 1 point. (b) 1 point.

Question 7: Ribbon pieces (2 points)
\(45 : 9 = 5\) because \(9 \times 5 = 45\).
He cuts 5 pieces.
Scoring: 1 point for a correct equation. 1 point for 5 pieces.
Question 8: Apples in boxes (3 points)
Apples in all: \(5 \times 8 = 40\).
Boxes: \(40 : 4 = 10\).
The stand fills 10 boxes.
Scoring: 1 point for 40. 1 point for dividing by 4. 1 point for 10 boxes.
Question 9: Write a story (3 points)
Sample story: Sofia shares 30 grapes equally among 5 friends. How many grapes does each friend get?
