Primary 3 Mathematics Quiz - Whole Numbers
Answer Key
Section A: Place Value (Questions 1–5)
1. In the number 4,738, which digit is in the hundreds place?
Answer: 7
Marks: 2
Working: In 4,738, the places from left to right are: thousands (4), hundreds (7), tens (3), ones (8). The digit in the hundreds place is 7.
Marking note: Award 2 marks for correct answer. Award 0 marks for any other answer.
2. What is the value of the digit 6 in 6,205?
Answer: 6,000
Marks: 2
Working: The digit 6 is in the thousands place in 6,205. Value of 6 = 6 × 1,000 = 6,000.
Marking note: Award 2 marks for 6,000. Award 0 marks for just "6" — students must give the value, not just the digit.
3. Write the number "three thousand, five hundred and twelve" in numerals.
Answer: 3,512
Marks: 2
Working: Three thousand = 3,000; five hundred = 500; twelve = 12. So 3,000 + 500 + 10 + 2 = 3,512.
Marking note: Award 2 marks for 3,512. Common mistake: writing 3,5012 or 3512 without comma — accept 3512.
4. The HDB block number is 3,849. What is the value of the digit 8 in this number?
Answer: 800
Marks: 2
Working: In 3,849, the digit 8 is in the hundreds place. Value of 8 = 8 × 100 = 800.
Marking note: Award 2 marks for 800. Award 0 marks for just "8".
5. Fill in the missing number: 5,000 + _____ + 30 + 7 = 5,437
Answer: 400
Marks: 2
Working: 5,437 = 5,000 + 400 + 30 + 7. The missing number is 400 (the hundreds place).
Marking note: Award 2 marks for 400. Award 1 mark if student shows correct place value reasoning but makes an arithmetic error.
Section B: Comparing and Ordering Numbers (Questions 6–10)
6. Which number is larger: 4,562 or 4,652?
Answer: 4,652
Marks: 2
Working: Both numbers have 4 thousands. Compare hundreds: 5 hundreds vs 6 hundreds. Since 6 > 5, 4,652 is larger.
Marking note: Award 2 marks for correct answer with or without working.
7. Arrange the following numbers in ascending order: 3,245 | 3,425 | 3,142 | 3,524
Answer: 3,142, 3,245, 3,425, 3,524
Marks: 2
Working: All numbers have 3 thousands. Compare hundreds: 1 < 2 < 4 < 5. So the order is 3,142 → 3,245 → 3,425 → 3,524.
Marking note: Award 2 marks for all four in correct order. Award 1 mark if 2–3 numbers are in correct position.
8. What is the smallest 4-digit number you can make using the digits 7, 2, 9, and 4 (each digit used once)?
Answer: 2,479
Marks: 2
Working: To make the smallest number, place the smallest digit in the highest place value. Smallest digit is 2 (thousands), then 4 (hundreds), then 7 (tens), then 9 (ones). Answer: 2,479.
Marking note: Award 2 marks for 2,479. Common mistake: 9,742 (largest, not smallest).
9. Put the correct symbol: 5,308 ⬜ 5,038
Answer: >
Marks: 2
Working: Both have 5 thousands. Compare hundreds: 3 hundreds vs 0 hundreds. Since 3 > 0, 5,308 > 5,038.
Marking note: Award 2 marks for >. Award 0 marks for < or =.
10. A school library has 2,876 English books and 2,768 Chinese books. Which type of book is there more of? How many more?
Answer: English books, 108 more
Marks: 2
Working: Compare: 2,876 > 2,768, so there are more English books. Difference: 2,876 − 2,768 = 108.
Marking note: Award 2 marks for "English books, 108 more". Award 1 mark if only the correct type is named without the difference, or if the difference is correct but the type is not named.
