This grade 4 multiplication test answer key gives the full solution and the scoring guide for each of the 9 test questions on multi-digit multiplication.
Use this answer key to score the multi-digit multiplication test. Every solution shows the partial products and a scoring guide that explains how the points are awarded, so a student who has the right method but a small slip still earns credit. The total is 20 points.
Grade 4 Multiplication Test Answer Key: questions 1–5
Question 1: Find the products (2 points)
-
Partial products: \(7 \times 4{,}000 = 28{,}000\), \(7 \times 300 = 2{,}100\), \(7 \times 60 = 420\), \(7 \times 8 = 56\).
Add: \(28{,}000 + 2{,}100 + 420 + 56 = 30{,}576\).
30,576
-
Partial products: \(60 \times 80 = 4{,}800\), \(60 \times 5 = 300\), \(3 \times 80 = 240\), \(3 \times 5 = 15\).
Add: \(4{,}800 + 300 + 240 + 15 = 5{,}355\).
5,355
Scoring: 1 point for each correct product.
Question 2: Area model (2 points)
\(40 \times 30 = 1{,}200\), \(40 \times 7 = 280\), \(6 \times 30 = 180\), \(6 \times 7 = 42\).
Total: \(1{,}200 + 280 + 180 + 42 = 1{,}702\). 1,702
Scoring: 1 point for the four partial products; 1 point for the correct total.
Question 3: Partial products (2 points)
Partial products: \(8 \times 3{,}000 = 24{,}000\), \(8 \times 200 = 1{,}600\), \(8 \times 6 = 48\).
Add: \(24{,}000 + 1{,}600 + 48 = 25{,}648\).
25,648
Scoring: 1 point for correct partial products; 1 point for the correct total.
Question 4: Priya's mistake (2 points)
Priya treated 508 as 50 + 8, but 508 is 500 + 8, so the hundreds part should be 6 × 500 = 3,000.
Correct: \(3{,}000 + 48 = 3{,}048\). 3,048
Scoring: 1 point for the explanation; 1 point for the correct product.
Question 5: Estimate and exact (2 points)
- \(50 \times 60 = 3{,}000\). 3,000
-
Partial products: \(40 \times 60 = 2{,}400\), \(40 \times 2 = 80\), \(9 \times 60 = 540\), \(9 \times 2 = 18\).
Add: \(2{,}400 + 80 + 540 + 18 = 3{,}038\).
3,038
Scoring: 1 point for each part.

Question 6: Properties (2 points)
Swap and regroup: \(5 \times 17 \times 2 = 17 \times (5 \times 2) = 17 \times 10 = 170\). The commutative and associative properties were used. 170
Scoring: 1 point for the correct product; 1 point for naming a correct property.
Question 7: Team baseballs (3 points)
-
Partial products: \(10 \times 10 = 100\), \(10 \times 4 = 40\), \(8 \times 10 = 80\), \(8 \times 4 = 32\).
Add: \(100 + 40 + 80 + 32 = 252\).
Partial areas 100, 40, 80, 32. 252 players
- \(3 \times 252 = 600 + 150 + 6 = 756\). 756 baseballs
Scoring: (a) 1 point. (b) 1 point for multiplying 3 by 252 and 1 point for the correct answer.
Question 8: Two stadiums (3 points)
Partial products: \(6 \times 2{,}000 = 12{,}000\), \(6 \times 400 = 2{,}400\), \(6 \times 70 = 420\), \(6 \times 5 = 30\).
Add: \(12{,}000 + 2{,}400 + 420 + 30 = 14{,}850\).
Stadium A has 14,850 seats. \(14{,}850 – 14{,}520 = 330\).
Stadium A has 330 more seats.
Scoring: 2 points for the correct seats in Stadium A; 1 point for the comparison.
Question 9: Multiples of ten (2 points)
- \(2 \times 6 = 12\) tens times 10: 1,200
- \(9 \times 5 = 45\), times 100: 4,500
Scoring: 1 point for each product.
