Primary 3 Mathematics Quiz - Whole Numbers (Answer Key)

Total Marks: 40
Questions: 20 (2 marks each)

Section A Answers

1. 7
Teaching note: Place value from right: ones (8), tens (3), hundreds (7), thousands (4). The hundreds digit is 7.
Common mistake: Picking 4 (thousands) instead of 7.

2. 6 000
Teaching note: Digit 6 is in thousands place, so its value is 6 × 1 000 = 6 000.
Marking: 2 marks for 6000; 0 if wrote 6.

3. 7 215
Teaching note: Seven thousand = 7 000, two hundred = 200, fifteen = 15 → 7 215.

4. 5 621
Teaching note: Compare left to right: thousands same (5), hundreds same (6), tens: 2 > 1, so 5 621 > 5 612.

5. 3 048, 3 084, 3 480, 3 804
Teaching note: Ascending = smallest to largest. Compare thousands (all 3), then hundreds: 0 < 4 < 8.
Marking: 2 marks if all four correct order.

6. 4 700
Teaching note: Round to nearest hundred: look at tens digit (5). Since 5 ≥ 5, round up hundreds: 4 657 → 4 700.

7. 2 000
Teaching note: Round to nearest thousand: look at hundreds digit (3). Since 3 < 5, round down: 2 345 → 2 000.

8. 1 350, 1 400
Teaching note: Pattern increases by 50 each step (1 250 − 1 200 = 50). So 1 300 + 50 = 1 350; +50 = 1 400.

9. 7 700
Teaching note: Decreasing by 100 each time: 8 000 → 7 900 → 7 800 → 7 700 → 7 600.

10. 3 470
Teaching note: Smallest even number: ones must be even (0 or 4). Use 0 in ones, smallest thousands (3), then 4, then 7: 3 470. (3 407 is odd.)

Section B Answers

11. The school with 3 452 pupils
Teaching note: Compare: thousands same, hundreds same (4), tens: 5 > 2, so 3 452 > 3 425.

12. 10 000
Teaching note: Round to nearest thousand: hundreds digit is 8 (≥5), so round up: 9 850 → 10 000.

13. Five thousand and six
Teaching note: 5 000 = five thousand, 006 = and six (no hundreds/tens).

14. 2 700, 2 900
Teaching note: Difference = 200 (2 300 − 2 100). Add 200: 2 500 + 200 = 2 700; +200 = 2 900.

15. 900
Teaching note: Digit 9 is in hundreds place → 9 × 100 = 900.

16. 6 730, 6 703, 6 370, 6 037
Teaching note: Descending = largest to smallest. Compare: 6 730 > 6 703 (tens 3>0) > 6 370 > 6 037.

Section C Answers

17. e.g., 5 150 (or any from 5 150–5 249)
Teaching note: Numbers rounding to 5 200 to nearest hundred are 5 150 to 5 249. Accept any valid.

Teaching note: Thousands=5, hundreds=0, tens=3, ones=1 → 5 031.

19. 9 421
Teaching note: Largest number: place largest digit in highest place: 9 (thousands), 4 (hundreds), 2 (tens), 1 (ones) → 9 421.

20. 4 200, 4 100
