TuitionGoWhere Practice Paper — Answer Key

Mathematics Primary 3 | Whole Numbers | Version 3 of 5

Section A: Multiple Choice (10 marks)

1. D [1]

  • The digit 6 is in the thousands place in 6 842.
  • Value of 6 = 6 × 1 000 = 6 000.
  • Common mistake: Choosing A (6) — this is the digit itself, not its value.

2. B [1]

  • In 3 751: 3 is in thousands, 7 is in hundreds, 5 is in tens, 1 is in ones.
  • Answer: 7.

3. B [1]

  • All numbers start with 4 (thousands place is the same).
  • Compare hundreds: 0 < 2 < 3.
  • So 4 032 is the smallest.
  • Answer: B.

4. C [1]

  • 4 367: the tens digit is 6, which is ≥ 5, so round up.
  • 4 367 → 4 400 (to the nearest hundred).
  • Common mistake: Choosing D (4 370) — this is rounding to the nearest ten, not hundred.

5. C [1]

  • An even number ends in 0, 2, 4, 6, or 8.
  • 5 814 ends in 4 → even.
  • Answer: C.

6. B [1]

  • Seven thousand and forty-three = 7 000 + 40 + 3 = 7 043.
  • Common mistake: Choosing C (7 403) — this is "seven thousand four hundred and three."

7. B [1]

  • The pattern increases by 100 each time: 2 100, 2 200, 2 300, 2 400, 2 500.
  • Answer: B.

8. B [1]

  • 1 000 more than 5 480 = 5 480 + 1 000 = 6 480.
  • Common mistake: Choosing A (5 580) — this is adding 100, not 1 000.

9. A [1]

  • Compare from left to right: all start with 6.
  • Hundreds place: 1 = 1 < 2 < 5.
  • For 6 125 and 6 152 (both have 1 hundred): compare tens → 2 < 5.
  • Ascending: 6 125, 6 152, 6 215, 6 521.
  • Answer: A.

10. C [1]

  • In 8 307: 8 is in thousands, 3 is in hundreds, 0 is in tens, 7 is in ones.
  • Value of 3 = 3 × 100 = 300.
  • Answer: C.

Section B: Short Answer (20 marks)

11. Four thousand five hundred and six [1]

  • 4 000 → four thousand; 500 → five hundred; 6 → six.
  • Note: There is no tens digit (0 tens), so we do not say "and zero tens."
  • Common mistake: Writing "four thousand five hundred and six" — the "and" before ones is acceptable in Singapore convention when there is a zero in the tens place.

12. [2 — ½ mark per correct row]

DigitPlaceValue
5thousands5 000
2hundreds200
7tens70
4ones4
  • Award ½ mark for each correct value. Accept "5000", "200", "70", "4" without comma separators.

13. (a) 3 456 [1]

  • 3 000 + 400 + 50 + 6 = 3 456.

(b) 8 thousands + 6 hundreds + 1 ten + 9 ones [1]

  • 8 619: 8 thousands, 6 hundreds, 1 ten, 9 ones.
  • Accept "1 ten" or "1" for the tens place.

14. (a) > [1]

  • 7 430 > 7 340 (compare hundreds: 4 > 3).

(b) < [1]

  • 2 999 < 3 000 (2 999 is 1 less than 3 000).

15. (a) 3 460 [1]

  • 3 457: ones digit is 7 (≥ 5), so round up the tens digit: 3 457 → 3 460.

(b) 6 820 [1]

  • 6 823: ones digit is 3 (< 5), so round down: 6 823 → 6 820.

16. 5 900, 6 000 [2]

  • Pattern increases by 100 each time.
  • 5 600, 5 700, 5 800, 5 900, 6 000.
  • Award 1 mark for each correct answer.

17. [2]

  • Working: 3 845 + 1 000 = 4 845
  • Answer: 4 845 books.
  • Award 1 mark for correct working, 1 mark for correct answer.
  • Accept any clear method (e.g., counting on, vertical addition).

18. (a) Monday [1]

  • 4 320 is the largest number.

(b) Tuesday [1]

  • 4 032 is the smallest number.
  • Method: Compare hundreds digit — 0 (Tuesday) is the smallest.

Section C: Structured / Word Problems (10 marks)

19. (a) [2]

  • Descending order (largest to smallest):
  • 2540,2 540, 2 504, 2450,2 450, 2 405
  • Award 2 marks for all four in correct order.
  • Award 1 mark if 2 out of 4 are in the correct position, or if the order is ascending instead of descending.

(b) [2]

  • Top collector: Bala ($2 540)
  • Lowest collector: Cindy ($2 405)
  • Working: 2540−2 540 − 2 405 = $135
  • Answer: $135
  • Award 1 mark for correct working, 1 mark for correct answer.
  • Common mistake: Subtracting in the wrong order (2405−2 405 − 2 540).

20. (a) [2]

  • Working: 1 450 + 2 780 = 4 230
  • Answer: 4 230 pens

Total: 40 marks
