Subject: Mathematics
Level: Primary 3
Paper: SA2
Total Marks: 80

---

SECTION A: Multiple-Choice Questions (20 marks)

1. Answer: (2) 4 [2]

Explanation: In the number 6 428, the digits represent: 6 thousands, 4 hundreds, 2 tens, 8 ones. The digit in the hundreds place is 4.

2. Answer: (4) 7 000 [2]

Explanation: In 7 305, the digit 7 is in the thousands place. Its value is 7 × 1 000 = 7 000.
Common mistake: Writing 7 instead of 7 000. Remember: "value of digit" means the digit × its place value.

3. Answer: (3) 4 268 [2]

Explanation: Compare thousands (all 4), then hundreds: 8, 6, 2, 8. The smallest hundreds digit is 2, so 4 268 is the smallest.

4. Answer: (3) 5 700 [2]

Explanation: To round to the nearest hundred, look at the tens digit (7). Since 7 ≥ 5, round up the hundreds digit from 6 to 7. 5 673 → 5 700.

5. Answer: (2) 6 310 [2]

Working:

  3 450
+ 2 860
-------
  6 310

Ones: 0+0=0, Tens: 5+6=11 (1 ten, carry 1 hundred), Hundreds: 4+8+1=13 (3 hundreds, carry 1 thousand), Thousands: 3+2+1=6.

6. Answer: (1) 4 573 [2]

Working:

  8 000
- 3 427
-------
  4 573

Subtract with regrouping: 8 000 = 7 990 + 10. 10-7=3, 9-2=7, 9-4=5, 7-3=4.

7. Answer: (2) 42 [2]

Explanation: 6 × 7 = 42. This is a multiplication table fact (6 times table).

8. Answer: (2) 7 [2]

Explanation: 56 ÷ 8 = 7 because 8 × 7 = 56. Use multiplication to check division.

9. Answer: (2) 4 500 [2]

Explanation: The pattern increases by 100 each time: 4 200, 4 300, 4 400, 4 500, 4 600.

10. Answer: (1) 652 [2]

Working: 4 528 - 3 876 = 652.
Subtract: 8-6=2, 12-7=5 (regroup), 4-8=6 (regroup), 3-3=0 → 652.

---

SECTION B: Short-Answer Questions (30 marks)

11. Eight thousand and forty-seven [2]

Explanation: 8 047 = 8 thousands + 0 hundreds + 4 tens + 7 ones. Write "eight thousand" (not "eight thousands"), then "and forty-seven". No "hundred" or "zero hundred" is said.

12. 5 000 [2]

Explanation: The digit 5 is in the thousands place. Value = 5 × 1 000 = 5 000.

13. 6 842, 6 482, 6 428, 6 284 [2]

Explanation: All have 6 thousands. Compare hundreds: 8, 4, 4, 2. Greatest is 6 842. For the two with 4 hundreds (6 482, 6 428), compare tens: 8 > 2, so 6 482 > 6 428. Smallest is 6 284.

14. 3 850 [2]

Explanation: Round to nearest ten. Ones digit is 9 (≥5), so round up tens digit from 4 to 5. 3 849 → 3 850.

15. 6 400 [2]

Explanation: Pattern decreases by 200 each time: 7 000, 6 800, 6 600, 6 400, 6 200.

16. 8 003 [2]

Working:

  4 325
+ 3 678
-------
  8 003

Ones: 5+8=13 (3, carry 1), Tens: 2+7+1=10 (0, carry 1), Hundreds: 3+6+1=10 (0, carry 1), Thousands: 4+3+1=8.

17. 4 433 [2]

Working:

  9 000
- 4 567
-------
  4 433

Regroup: 9 000 = 8 990 + 10. 10-7=3, 9-6=3, 9-5=4, 8-4=4.

18. 72 [2]

Explanation: 8 × 9 = 72. Multiplication table fact (8 times table or 9 times table).

19. 8 [2]

Explanation: 72 ÷ 9 = 8 because 9 × 8 = 72.

20. 1 404 [2]

Working:

    234
  ×   6
  -----
   1404

4×6=24 (4, carry 2), 3×6=18+2=20 (0, carry 2), 2×6=12+2=14.

8÷5=1 rem 3, bring down 4 → 34÷5=6 rem 4, bring down 5 → 45÷5=9.

22. 6 245 [2]

Working: 3 456 + 2 789 = 6 245.
Number sentence: 3 456 + 2 789 = 6 245

23. 2 655 [2]

Working: 5 000 - 2 345 = 2 655.
Number sentence: 5 000 - 2 345 = 2 655

24. 96 [2]

Working: 8 × 12 = 96.
Number sentence: 8 × 12 = 96
Alternative: 8 × 10 = 80, 8 × 2 = 16, 80 + 16 = 96.

25. 60 [2]

Working: 480 ÷ 8 = 60.
Number sentence: 480 ÷ 8 = 60
Check: 60 × 8 = 480.

SECTION C: Long-Answer Questions (30 marks)

26. [3]

(a) 4 000, 3 750 [2]
Working: Pattern decreases by 250 each time.
4 250 - 250 = 4 000
4 000 - 250 = 3 750

(b) Subtract 250 from the previous number. [1]
Explanation: The difference between consecutive terms is -250 (5 000 - 4 750 = 250, 4 750 - 4 500 = 250, etc.).

Check: 400 × 9 = 3 600.

(b) 2 000 [2]
Working: 5 boxes × 400 cookies = 2 000 cookies.
Number sentence: 5 × 400 = 2 000

---

29. [5]

(a) 5 630 [2]
Working: Saturday: 4 250. Sunday: 4 250 + 1 380 = 5 630.

  4 250
+ 1 380
-------
  5 630

(b) 3 480 [2]
Working: Monday: 5 630 - 2 150 = 3 480.
