Primary 3 Mathematics Quiz - Whole Numbers (Answer Key)

Total Marks: 50

Section A: Multiple Choice Questions (10 × 1 mark = 10 marks)

1. Answer: (2)
Explanation: In the number 4 728, the digits from left to right represent: thousands (4), hundreds (7), tens (2), ones (8). The digit in the hundreds place is 7.
Marking: 1 mark for correct option.

2. Answer: (4)
Explanation: The digit 6 is in the thousands place. Its value is 6 × 1 000 = 6 000.
Common mistake: Students may confuse "digit" (which is 6) with "value of digit" (which is 6 000).
Marking: 1 mark for correct option.

3. Answer: (3)
Explanation: Compare numbers starting from the thousands place (all have 3). Then compare hundreds: 8, 4, 2, 2. The smallest hundreds digit is 2. Between 3 248 and 3 284, compare tens: 4 < 8, so 3 248 is the smallest.
Marking: 1 mark for correct option.

4. Answer: (1)
Explanation: Ascending order means smallest to largest. Compare thousands (all 5), then hundreds: 1, 2, 6, 6. For the two numbers with 6 hundreds (5 612 and 5 621), compare tens: 1 < 2. Order: 5 126, 5 261, 5 612, 5 621.
Marking: 1 mark for correct option.

5. Answer: (2)
Explanation: To round to the nearest hundred, look at the tens digit (8). Since 8 ≥ 5, round up the hundreds digit from 7 to 8. 4 789 → 4 800.
Marking: 1 mark for correct option.

6. Answer: (3)
Explanation: 100 more than 3 456 means adding 100 to the hundreds place: 3 456 + 100 = 3 556.
Marking: 1 mark for correct option.

7. Answer: (2)
Explanation: The pattern increases by 100 each time: 2 345 + 100 = 2 445, 2 445 + 100 = 2 545, 2 545 + 100 = 2 645, 2 645 + 100 = 2 745.
Marking: 1 mark for correct option.

8. Answer: (1)
Explanation: 7 thousands = 7 000, 4 hundreds = 400, 9 tens = 90, 3 ones = 3. Sum = 7 000 + 400 + 90 + 3 = 7 493.
Marking: 1 mark for correct option.

9. Answer: (1)
Explanation: 6 000 − 4 328 = 1 672. Working:

  6 0 0 0
− 4 3 2 8
---------
  1 6 7 2

Marking: 1 mark for correct option.

10. Answer: (1)
Explanation: Total books = 4 587. Storybooks = 2 349. Non-storybooks = 4 587 − 2 349 = 2 238.
Marking: 1 mark for correct option.

Section B: Short Answer Questions (10 × 2 marks = 20 marks)

11. Answer: Eight thousand and forty-six
Explanation: 8 046 = 8 thousands + 0 hundreds + 4 tens + 6 ones. In words: "Eight thousand and forty-six". Note: "and" is used before the tens/ones when there are zero hundreds.
Marking: 2 marks for correct spelling and format. 1 mark for minor spelling error (e.g., "fourty" instead of "forty").

12. Answer: 5 072
Explanation: 5 thousands = 5 000, 0 hundreds = 0, 7 tens = 70, 2 ones = 2. Total = 5 000 + 0 + 70 + 2 = 5 072.
Marking: 2 marks for correct answer. 1 mark if place value understanding shown but calculation error.

13. Answer: 500
Explanation: 6 000 + ___ + 30 + 4 = 6 534. The missing value is in the hundreds place. 6 534 − 6 000 − 30 − 4 = 500.
Marking: 2 marks for correct answer.

14. Answer: <
Explanation: Compare 4 892 and 4 982. Thousands: both 4. Hundreds: 8 < 9. Therefore 4 892 < 4 982.
Marking: 2 marks for correct symbol.

15. Answer: 7 503
Explanation: To form the largest 4-digit odd number:

  • The ones digit must be odd (3, 5, or 7). Choose the smallest odd digit for ones to keep larger digits for higher places → 3.
  • Arrange remaining digits (7, 5, 0) in descending order for thousands, hundreds, tens: 7, 5, 0.
  • Number: 7 503.
    Common mistake: Using 7 as ones digit gives 5 037 which is smaller.
    Marking: 2 marks for correct answer. 1 mark for correct odd number but not the largest (e.g., 7 530 is even, 7 305 is smaller).

16. Answer: 6 000
Explanation: The pattern decreases by 250 each time:
7 000 − 250 = 6 750
6 750 − 250 = 6 500
6 500 − 250 = 6 250
6 250 − 250 = 6 000
6 000 − 250 = 5 750 ✓
Marking: 2 marks for correct answer.

17. Answer: 3 650
Explanation: To round to the nearest ten, look at the ones digit (8). Since 8 ≥ 5, round up the tens digit from 4 to 5. 3 648 → 3 650.
Marking: 2 marks for correct answer.

18. Answer: 6 245
Explanation:

  2 4 5 6
+ 3 7 8 9
---------
  6 2 4 5

Working: 6+9=15 (write 5, carry 1), 5+8+1=14 (write 4, carry 1), 4+7+1=12 (write 2, carry 1), 2+3+1=6.
Marking: 2 marks for correct answer. 1 mark for correct method with calculation error.

19. Answer: 3 124
Explanation:

  5 0 0 0
− 1 8 7 6
---------
  3 1 2 4

Working: Regrouping needed across zeros.
Marking: 2 marks for correct answer. 1 mark for correct method with calculation error.

20. Answer: 8 002
Explanation: January: 4 328, February: 3 674. Total = 4 328 + 3 674 = 8 002.

  4 3 2 8
+ 3 6 7 4
---------
  8 0 0 2

Marking: 2 marks for correct answer. 1 mark for correct method with calculation error.

Total: 50 marks

General Marking Notes:

  • For Section B, award method marks where working is shown even if final answer is incorrect.
  • Accept alternative valid methods (e.g., number line for rounding, place value chart for comparison).
  • Deduct 1 mark for missing units ($ or "books", "toys", etc.) in final answer where applicable.
  • For spelling in Q11, accept phonetic spelling if clear (e.g., "fourty" for "forty" - 1 mark deduction only).
