Primary 1 Mathematics Quiz - Addition Subtraction: Answer Key

Total Marks: 30 marks

Section A: Simple Addition and Subtraction

[10 marks total]

1. 3+4=3 + 4 = 7

[1 mark]

Explanation: Start with 3, then count on 4 more: 4, 5, 6, 7. Or use your fingers: hold up 3 fingers, then hold up 4 more, count all fingers showing.

2. 9−5=9 - 5 = 4

[1 mark]

Explanation: Start with 9, count backwards 5: 8, 7, 6, 5, 4. Or think: "What number plus 5 makes 9?" Since 4+5=94 + 5 = 9, then 9−5=49 - 5 = 4.

3. 6+7=6 + 7 = 13

[1 mark]

Explanation: Use the "make 10" strategy. 6+76 + 7 can be split as 6+4+3=10+3=136 + 4 + 3 = 10 + 3 = 13. Or count on 7 from 6: 7, 8, 9, 10, 11, 12, 13.

4. 12−8=12 - 8 = 4

[1 mark]

Explanation: Start with 12, count backwards 8: 11, 10, 9, 8, 7, 6, 5, 4. Or use number bonds: since 8+4=128 + 4 = 12, then 12−8=412 - 8 = 4.

5. 15+4=15 + 4 = 19

[1 mark]

Explanation: Add the ones: 5 ones + 4 ones = 9 ones. The tens stay the same: 1 ten. So 15+4=1915 + 4 = 19.

6. 20−6=20 - 6 = 14

[1 mark]

Explanation: Start with 20, count backwards 6: 19, 18, 17, 16, 15, 14. Or break it down: 20−10=1020 - 10 = 10, but that's too much, so 20−6=1420 - 6 = 14.

7. 8+9=8 + 9 = 17

[1 mark]

Explanation: Use "make 10" strategy. 8+9=8+2+7=10+7=178 + 9 = 8 + 2 + 7 = 10 + 7 = 17. Or 9+9=189 + 9 = 18, so 8+9=178 + 9 = 17 (one less).

8. 17−9=17 - 9 = 8

[1 mark]

Explanation: Use "make 10" strategy for subtraction. 17−9=17−7−2=10−2=817 - 9 = 17 - 7 - 2 = 10 - 2 = 8. Or think: 9+8=179 + 8 = 17, so 17−9=817 - 9 = 8.

9. 23+5=23 + 5 = 28

[1 mark]

Explanation: Add the ones: 3 ones + 5 ones = 8 ones. The tens stay the same: 2 tens. So 23+5=2823 + 5 = 28.

10. 31−7=31 - 7 = 24

[1 mark]

Explanation: Break 31 into 20 and 11. Then 11−7=411 - 7 = 4, and 20+4=2420 + 4 = 24. Or count backwards from 31: 30, 29, 28, 27, 26, 25, 24 (7 steps).

Section B: Number Bonds and Making Tens

[10 marks total]

11. 8+8 + 2 =10= 10

[1 mark]

Explanation: Number bonds of 10: two numbers that add up to 10. Think "What goes with 8 to make 10?" Count on from 8: 9, 10. That's 2 more. So 8+2=108 + 2 = 10.

12. 9 +6=15+ 6 = 15

[1 mark]

Explanation: Think "What number plus 6 equals 15?" or reverse the addition: 15−6=915 - 6 = 9. Check: 9+6=159 + 6 = 15 ✓

13. 14−14 - 8 =6= 6

[1 mark]

Explanation: Think "What number taken away from 14 leaves 6?" or "What plus 6 equals 14?" Since 8+6=148 + 6 = 14, then 14−8=614 - 8 = 6.

14. 16 −9=7- 9 = 7

[1 mark]

Explanation: Reverse the subtraction: what number minus 9 equals 7? This means ?=7+9=16? = 7 + 9 = 16. Check: 16−9=716 - 9 = 7 ✓

15. The missing number is 8

8=17−9\boxed{8} = 17 - 9

[2 marks]

Explanation: In a number bond, the top number (whole) equals the sum of the two bottom numbers (parts). So part = whole − other part.

Step 1: Identify the whole (17) and one part (9) Step 2: Missing part = 17−917 - 9 Step 3: 17−9=817 - 9 = 8 (using make 10: 17−7=1017 - 7 = 10, then 10−2=810 - 2 = 8)

Common mistake: Writing 8 in the circle but not showing understanding of the number bond relationship.

Marking: 1 mark for correct answer, 1 mark for showing number bond understanding

16. 7 ++ 5 == 12

There are 12 stars altogether.

[2 marks]

Explanation: Count the stars in each group from the image. First group has 7 stars, second group has 5 stars. "Altogether" means we add.

Step 1: Count stars in first group = 7 Step 2: Count stars in second group = 5 Step 3: Add: 7+5=127 + 5 = 12

Use "make 10": 7+5=7+3+2=10+2=127 + 5 = 7 + 3 + 2 = 10 + 2 = 12

17.

(a) 7 boxes are filled

(b) 3 boxes are empty

(c) 7 ++ 3 =10= 10 (or 3+7=103 + 7 = 10)

[2 marks]

Explanation: A 10-frame always has 10 boxes total. Count the filled (shaded) boxes: 7. The empty boxes are the rest: 10−7=310 - 7 = 3. The addition sentence shows both parts make the whole: 7+3=107 + 3 = 10.

Section C: Word Problems

[10 marks total]

18. Mei Ling has 8 stickers left.

[3 marks]

Working: 14−6=814 - 6 = 8

Step-by-step explanation:

Step 1: Understand the problem. Mei Ling starts with 14 stickers. "Gives away" means we subtract — she has fewer stickers now.

Step 2: Identify the numbers. Start: 14 stickers. Given away: 6 stickers.

Step 3: Choose the operation. "Gives away" → subtraction.

Step 4: Calculate: 14−6=814 - 6 = 8

Method: Make 10: 14−4=1014 - 4 = 10, then 10−2=810 - 2 = 8. So 14−6=814 - 6 = 8.

Step 5: Answer the question. Mei Ling has 8 stickers left.

Marking breakdown:

  • 1 mark: Correct operation identified (subtraction) or correct setup
  • 1 mark: Correct working shown
  • 1 mark: Correct final answer with units

Common mistake: Adding instead of subtracting (14+6=2014 + 6 = 20). Watch for "gives away," "left," "remaining" — these mean subtraction.

19. There are 17 balloons altogether.

[3 marks]

Working: 8+9=178 + 9 = 17

Step-by-step explanation:

Step 1: Understand the problem. We have two groups of balloons. "Altogether" means we need to find the total — we add.

Step 2: Identify the numbers. Red balloons: 8. Blue balloons: 9.

Step 3: Choose the operation. "Altogether" → addition.

Step 4: Calculate: 8+9=178 + 9 = 17

Method: Make 10: 8+9=8+2+7=10+7=178 + 9 = 8 + 2 + 7 = 10 + 7 = 17. Or 9+9=189 + 9 = 18, so 8+9=178 + 9 = 17.

Step 5: Answer the question. There are 17 balloons altogether.

Marking breakdown:

  • 1 mark: Correct operation identified (addition) or correct setup
  • 1 mark: Correct working shown
  • 1 mark: Correct final answer with units

Common mistake: Subtracting instead of adding. Watch for "altogether," "total," "in all" — these mean addition.

20. Raju has 8 more marbles than Kai Wen.

[4 marks]

Working: 25−17=825 - 17 = 8

Or: 25−15=1025 - 15 = 10 10−2=810 - 2 = 8

Step-by-step explanation:

Step 1: Understand the problem. We need to compare two amounts. "How many more" means we find the difference — we subtract the smaller number from the larger number.

Step 2: Identify the numbers. Raju: 25 marbles (more). Kai Wen: 17 marbles (fewer).

Step 3: Choose the operation. "How many more" → subtraction (larger − smaller).

Step 4: Calculate: 25−1725 - 17

Method: Break it down. 25−10=1525 - 10 = 15, then 15−7=815 - 7 = 8. Or: 25−17=25−15−2=10−2=825 - 17 = 25 - 15 - 2 = 10 - 2 = 8. Or: add up from 17: 17+3=2017 + 3 = 20, 20+5=2520 + 5 = 25, so 3+5=83 + 5 = 8.

Step 5: Answer the question. Raju has 8 more marbles than Kai Wen.

Marking breakdown:

  • 1 mark: Correct understanding (find the difference / "how many more")
  • 1 mark: Correct numbers chosen (25 − 17, not 25 + 17)
  • 1 mark: Correct working with valid method shown
  • 1 mark: Correct final answer with correct wording ("more marbles")

Common mistakes:

  • Adding instead: 25+17=4225 + 17 = 42 — this would be the total if they combined marbles
  • Getting confused with "more than" wording — remember "how many more" always means subtraction of the two numbers
