Answers
Primary 2 Mathematics Quiz - Numbers (Answer Key)
Total Marks: 30
Section A: Multiple Choice Questions (5 × 1 mark = 5 marks)
1. Answer: (3) 800
Explanation: In the number 842, the digit 8 is in the hundreds place. The value of a digit in the hundreds place is the digit × 100. So, 8 × 100 = 800.
Common mistake: Confusing "digit" (the symbol 8) with "value" (800).
2. Answer: (3) 467
Explanation: Compare the hundreds digit first. 467 and 476 have 4 hundreds, while 647 and 674 have 6 hundreds. So the smallest numbers are 467 and 476. Between these, compare the tens digit: 467 has 6 tens, 476 has 7 tens. 6 tens < 7 tens, so 467 is the smallest.
3. Answer: (2) 380
Explanation: The pattern increases by 20 each time: 320 + 20 = 340, 340 + 20 = 360, 360 + 20 = 380, 380 + 20 = 400. The missing number is 380.
4. Answer: (1) 537
Explanation: 5 hundreds = 500, 3 tens = 30, 7 ones = 7. Adding them: 500 + 30 + 7 = 537.
5. Answer: (3) 482
Explanation: An even number can be divided equally into two groups (ends with 0, 2, 4, 6, or 8). 482 ends with 2, so it is even. 245, 367, and 519 end with odd digits (5, 7, 9), so they are odd numbers.
Section B: Short Answer Questions (10 × 2 marks = 20 marks)
6. Answer: Seven hundred and sixty-four
Explanation: 764 = 700 (seven hundred) + 60 (sixty) + 4 (four). In words: "Seven hundred and sixty-four".
Marking note: Accept "Seven hundred sixty-four" (without "and").
7. Answer: 500
Explanation: In 593, the digit 5 is in the hundreds place. Value = 5 × 100 = 500.
8. Answer: 821, 812, 182, 128
Explanation: Compare hundreds first: 821 and 812 have 8 hundreds; 182 and 128 have 1 hundred. So 821 and 812 are bigger. Between 821 and 812, compare tens: 821 has 2 tens, 812 has 1 ten → 821 > 812. Between 182 and 128, compare tens: 182 has 8 tens, 128 has 2 tens → 182 > 128. Order: 821, 812, 182, 128.
9. Answer: 600, 650
Explanation: The pattern increases by 50 each time: 450 + 50 = 500, 500 + 50 = 550, 550 + 50 = 600, 600 + 50 = 650, 650 + 50 = 700.
10. Answer: 609
Explanation: 6 hundreds = 600, 0 tens = 0, 9 ones = 9. 600 + 0 + 9 = 609.
Key concept: Zero as a placeholder in the tens place.
11. Answer: 587
Explanation: 100 more than 487 means adding 100 to the hundreds place: 487 + 100 = 587.
Mental strategy: Increase the hundreds digit by 1 (4 → 5), keep tens and ones the same.
12. Answer: 295
Explanation: 10 less than 305 means subtracting 10 from the tens place. 305 - 10 = 295.
Mental strategy: Reduce the tens digit by 1 (0 → 9, with regrouping from hundreds: 3 hundreds becomes 2 hundreds, 0 tens becomes 10 tens, then 10 - 1 = 9 tens).
13. Answer: 357, 591, 715
Explanation: Odd numbers end with 1, 3, 5, 7, or 9.
- 234 ends with 4 → even
- 357 ends with 7 → odd
- 468 ends with 8 → even
- 591 ends with 1 → odd
- 602 ends with 2 → even
- 715 ends with 5 → odd
14. Answer: 720, 700
Explanation: The pattern decreases by 20 each time: 780 - 20 = 760, 760 - 20 = 740, 740 - 20 = 720, 720 - 20 = 700, 700 - 20 = 680.
15. Answer: 472
Explanation: 4 hundreds = 400, 7 tens = 70, 2 ones = 2. 400 + 70 + 2 = 472.
Section C: Problem Sums (7 marks)
16. Answer: 583 books (2 marks)
Working:
345 + 238 = 583
Step-by-step:
- Ones: 5 + 8 = 13 → write 3, carry 1 ten
- Tens: 4 + 3 + 1 (carried) = 8 tens
- Hundreds: 3 + 2 = 5 hundreds
- Total: 583
Mark allocation: 1 mark for correct method/working, 1 mark for correct answer with unit.
17. Answer: 318 boys (2 marks)
Working:
567 - 249 = 318
Step-by-step (subtraction with regrouping):
- Ones: 7 - 9 (cannot, regroup 1 ten from tens) → 17 - 9 = 8
- Tens: 6 becomes 5 after regrouping; 5 - 4 = 1 ten
- Hundreds: 5 - 2 = 3 hundreds
- Total: 318
Mark allocation: 1 mark for correct method/working, 1 mark for correct answer with unit.
18. Answer: 109 cookies (3 marks)
Working:
Method 1: Subtract total sold from total baked
Total sold = 185 + 132 = 317
Cookies left = 426 - 317 = 109
Method 2: Subtract sequentially
426 - 185 = 241 (left after morning)
241 - 132 = 109 (left after afternoon)
Step-by-step (Method 1):
- Add sold: 185 + 132 = 317
- Ones: 5 + 2 = 7
- Tens: 8 + 3 = 11 → write 1, carry 1 hundred
- Hundreds: 1 + 1 + 1 = 3
- Subtract from total: 426 - 317 = 109
- Ones: 6 - 7 (regroup) → 16 - 7 = 9
- Tens: 2 becomes 1; 1 - 1 = 0
- Hundreds: 4 - 3 = 1
Mark allocation: 1 mark for finding total sold (or first subtraction), 1 mark for final subtraction, 1 mark for correct answer with unit.
