TuitionGoWhere Practice Paper — Answer Key

Mathematics Primary 3 | Practice Paper 1 of 5 — Whole Numbers

Section A: Multiple Choice (10 marks)

1. What is the value of the digit 6 in 4 638?

  • Answer: (C) 600 [2]
  • Working: In 4 638, the digit 6 is in the hundreds place. Value = 6 × 100 = 600.
  • Common mistake: Choosing (A) 6 — this is the digit itself, not its value.

2. Which is the smallest number?

  • Answer: (B) 3 142 [2]
  • Working: All numbers start with 3 (thousands). Compare hundreds: 1 < 2 < 4. So 3 142 and 3 124 both have 1 hundred. Compare tens: 2 < 4. So 3 124 is smaller than 3 142. Wait — rechecking: 3 124 vs 3 142: hundreds are both 1; tens: 2 vs 4 → 2 < 4, so 3 124 is smallest.
  • Corrected Answer: (D) 3 124 [2]
  • Common mistake: Not comparing all place values carefully.

3. Round 4 567 to the nearest hundred.

  • Answer: (C) 4 600 [2]
  • Working: Look at the tens digit: 6. Since 6 ≥ 5, round up. 4 567 → 4 600.
  • Common mistake: Choosing (A) 4 500 by rounding down when the tens digit is 6 or more.

4. Which number is even and the largest?

  • Answer: (B) 5 380 [2]
  • Working: Check even numbers (ones digit is 0, 2, 4, 6, or 8): Only (B) 5 380 ends in 0 (even). All others end in 1, 9, 7 (odd). So 5 380 is the only even number and therefore the largest even number.
  • Common mistake: Choosing the largest number overall without checking if it is even.

5. What is the missing number in the pattern? 2 300, 2 400, 2 500, _____, 2 700

  • Answer: (B) 2 600 [2]
  • Working: The pattern increases by 100 each time. 2 500 + 100 = 2 600. Check: 2 600 + 100 = 2 700 ✓
  • Common mistake: Choosing (A) 2 550 by adding 50 instead of 100.

Section B: Short Answer (20 marks)

6. Write 7 405 in words.

  • Answer: Seven thousand, four hundred and five [2]
  • Marking: Award 2 marks for correct words. Accept "seven thousand four hundred and five" (comma optional). Do not accept "seven thousand four hundred and five" written as "7 thousand 4 hundred 5" (must be in words).
  • Common mistake: Writing "seven thousand four hundred and five" as "seven thousand four hundred five" — at P3, "and" is expected after hundreds.

7. Write six thousand, two hundred and eight in numerals.

  • Answer: 6 208 [2]
  • Working: 6 thousands = 6 000; 2 hundreds = 200; 0 tens; 8 ones. So 6 000 + 200 + 8 = 6 208.
  • Common mistake: Writing 6 280 (swapping tens and ones) or 6000208.

8. Arrange in ascending order: 5 672, 5 276, 5 762, 5 627

  • Answer: 5 276, 5 627, 5 672, 5 762 [2]
  • Working: All start with 5 (thousands). Compare hundreds: 2 < 6 < 7. So 5 276 is smallest. For 5 627 and 5 672 (both have 6 hundreds): compare tens: 2 < 7, so 5 627 < 5 672. Largest is 5 762 (7 hundreds).
  • Marking: Award 2 marks for all correct. Award 1 mark if 2–3 numbers are in correct position.

9. Value of digit 3 in:

  • (a) 3 841: 3 000 [1]
    • Working: 3 is in the thousands place. Value = 3 × 1 000 = 3 000.
  • (b) 5 372: 300 [1]
    • Working: 3 is in the hundreds place. Value = 3 × 100 = 300.

10. Fill in the blanks.

  • (a) 8 000 + 200 + 40 + 6 = 8 246 [1]
    • Working: 8 246 − 8 000 − 40 − 6 = 200.
  • (b) 9 thousands + 0 hundreds + 7 tens + 3 ones = 9 073 [1]
    • Working: 9 000 + 0 + 70 + 3 = 9 073.

11. Round to the nearest ten.

  • (a) 1 435 → 1 440 [1]
    • Working: Ones digit is 5. Since 5 ≥ 5, round up. 1 435 → 1 440.
  • (b) 6 789 → 6 790 [1]
    • Working: Ones digit is 9. Since 9 ≥ 5, round up. 6 789 → 6 790.

12. Using digits 2, 8, 5, 1 (each used once):

  • (a) Largest 4-digit number: 8 521 [1]
    • Working: Arrange digits in descending order: 8, 5, 2, 1 → 8 521.
  • (b) Smallest 4-digit number: 1 258 [1]
    • Working: Arrange digits in ascending order: 1, 2, 5, 8 → 1 258.

13. Find the missing number in each pattern.

  • (a) 1 100, 1 300, 1 500, 1 700, 1 900 [1]
    • Working: Pattern increases by 200 each time. 1 500 + 200 = 1 700.
  • (b) 9 000, 8 500, 8 000, 7 500, 7 000 [1]
    • Working: Pattern decreases by 500 each time. 8 000 − 500 = 7 500.

14. A school library has 3 742 books. It receives 200 more.

  • Answer: 3 942 books [2]
  • Working: 3 742 + 200 = 3 942.
  • Marking: Award 2 marks for correct answer with working. Award 1 mark for correct answer without working, or correct working with minor arithmetic error.

15. Put >, < or = in each box.

  • (a) 4 506 < 4 560 [1]
    • Working: Thousands and hundreds are the same (4 and 5). Compare tens: 0 < 6. So 4 506 < 4 560.
  • (b) 7 003 < 7 030 [1]
    • Working: Thousands and hundreds are the same (7 and 0). Compare tens: 0 < 3. So 7 003 < 7 030.
  • (c) 2 888 = 2 888 [1]
    • Working: Both numbers are identical.

Section C: Structured / Word Problems (10 marks)

16. Singapore Zoo visitors table.

DayVisitors
Monday4 356
Tuesday4 635
Wednesday4 536
Thursday4 365
  • (a) Most visitors: Tuesday [1]
    • Working: Compare all numbers. Tuesday (4 635) has the highest hundreds digit (6) among all.
  • (b) Fewest visitors: Monday [1]
    • Working: Monday (4 356) has the smallest hundreds digit (3). Compare with Thursday (4 365): both have 3 hundreds; compare tens: 5 < 6, so Monday (4 356) < Thursday (4 365). Monday is fewest.
  • (c) Fewest to most: 4 356, 4 365, 4 536, 4 635 [2]
    • Working: All start with 4. Compare hundreds: 3 < 5 < 6. For the two with 3 hundreds: 4 356 (tens=5) < 4 365 (tens=6). Order: Monday (4 356), Thursday (4 365), Wednesday (4 536), Tuesday (4 635).
    • Marking: Award 2 marks for all correct. Award 1 mark if 2–3 numbers are in correct position.

17. A shop sold 2 450 red pens and 1 875 blue pens.

  • (a) Total pens sold: 4 325 pens [2]

    • Working: 2 450 + 1 875
      2 4 5 0
+ 1 8 7 5
---------
  4 3 2 5

    Answer: 4 325 pens.

  • (b) More red pens than blue: 575 pens [2]

    • Working: 2 450 − 1 875
      2 4 5 0
− 1 8 7 5
---------
    5 7 5

    Answer: 575 more red pens.

    • Marking: Award 2 marks for correct answer with working. Award 1 mark for correct method with minor arithmetic error.

18. Charity drive recyclable items.

  • Class 3A: 1 250 | Class 3B: 1 520 | Class 3C: 1 025 | Class 3D: 1 205

  • (a) Most items: Class 3B [1]

    • Working: Compare hundreds: 3B has 5 hundreds (1 520), which is the highest.

  • (b) Fewest items: Class 3C [1]

    • Working: 3C has 0 hundreds (1 025), which is the lowest.

  • (c) Most to fewest: 3B (1 520), 3A (1 250), 3D (1 205), 3C (1 025) [2]

    • Working: Compare hundreds: 5 > 2 > 0. For 3A and 3D (both 2 hundreds): compare tens: 5 > 0, so 3A > 3D. Order: 3B, 3A, 3D, 3C.
    • Marking: Award 2 marks for all correct. Award 1 mark if 2–3 classes are in correct position.

19. Number clues:

  • Thousands digit: 6

  • Hundreds digit: 0

  • Tens digit: 3 more than hundreds = 0 + 3 = 3

  • Ones digit: 2

  • Answer: 6 032 [2]

  • Working: Thousands=6, Hundreds=0, Tens=3, Ones=2 → 6 032.

  • Marking: Award 2 marks for correct answer. Award 1 mark if student shows correct reasoning but makes an arithmetic error in the tens digit.

20. HDB town populations.

  • Town A: 8 467 | Town B: 8 647 | Town C: 8 746 | Town D: 8 476

  • (a) Largest population: Town C (8 746) [1]

    • Working: All start with 8. Compare hundreds: 7 (Town C) is the largest. So Town C has the largest population.

  • (b) Smallest population: Town A (8 467) [1]

    • Working: Compare hundreds: 4 (Towns A and D) is smallest. Compare tens: 6 (Town A) < 7 (Town D). So Town A (8 467) is smallest.
