This grade 4 add test answer key gives the full solution and the scoring guide for each of the 9 test questions on adding and subtracting multi-digit numbers.
Use this answer key to score the test on adding and subtracting multi-digit numbers. Each solution shows the regrouping and a scoring guide that explains how the points are awarded, so a partly correct answer earns partial credit. The total is 20 points.
Grade 4 Add Test Answer Key: questions 1–5
Question 1: Adding (2 points)
- \(4{,}758 + 3{,}689 = 8{,}447\). 8,447
- \(52{,}384 + 19{,}847 = 72{,}231\). 72,231
Scoring: 1 point for each correct sum.
Question 2: Subtracting (2 points)
- \(7{,}402 – 2{,}865 = 4{,}537\). 4,537
- \(90{,}000 – 46{,}318 = 43{,}682\). 43,682
Scoring: 1 point for each correct difference.
Question 3: Fans at three games (2 points)
- \(14{,}256 + 18{,}739 = 32{,}995\). 32,995 fans
- \(21{,}405 – 14{,}256 = 7{,}149\). 7,149 more fans
Scoring: 1 point for each part.
Question 4: Liam's subtraction (2 points)
Check: \(4{,}642 + 2{,}458\) = \(7{,}100\), not \(6{,}000\). So Liam’s answer is wrong (he probably did not regroup across the zeros).
Correct: \(6{,}000 – 2{,}458 = 3{,}542\). 3,542
Scoring: 1 point for showing the check fails; 1 point for the correct difference 3,542.
Question 5: Missing numbers (2 points)
- \(10{,}204 – 3{,}659 = 6{,}545\). 6,545
- \(8{,}000 – 2{,}347 = 5{,}653\). 5,653
Scoring: 1 point for each missing number.

Question 6: Three addends (2 points)
\(18{,}205 + 4{,}967 = 23{,}172\); then \(23{,}172 + 30{,}418 = 53{,}590\).
53,590
Scoring: 1 point for a correct partial sum; 1 point for the correct total.
Question 7: Can drive (3 points)
- \(6{,}874 + 9{,}359 = 16{,}233\). 16,233 cans
- \(25{,}000 – 16{,}233 = 8{,}767\). 8,767 cans
Scoring: (a) 1 point. (b) 1 point for setting up 25,000 − 16,233 and 1 point for the correct answer.
Question 8: Truck route (3 points)
Miles driven: \(1{,}486 + 1{,}729 = 3{,}215\), then \(3{,}215 + 1{,}358 = 4{,}573\).
Miles left: \(5{,}000 – 4{,}573 = 427\).
427 miles
Scoring: 1 point for the total driven, 1 point for the subtraction setup, 1 point for the correct answer.
Question 9: Compare (2 points)
- \(6{,}205 + 3{,}798 = 10{,}003\), which is greater than 10,000. >
- \(12{,}000 – 4{,}555 = 7{,}445\). =
Scoring: 1 point for each correct symbol.
