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 "value" (800) with "digit" (8) or "place" (hundreds).

2. Answer: (2) 637
Explanation: Compare the hundreds digit first: all numbers have 6 hundreds. Then compare the tens digit: 637 has 3 tens, 673 has 7 tens, 736 has 3 tens (but 7 hundreds), 763 has 6 tens (but 7 hundreds). Among the 600s, 637 (3 tens) is smaller than 673 (7 tens).
Method: Compare hundreds → tens → ones.

3. Answer: (1) 529
Explanation: 5 hundreds = 500, 2 tens = 20, 9 ones = 9. 500 + 20 + 9 = 529. This is the expanded form of the number.

4. Answer: (2) 480
Explanation: The pattern increases by 20 each time: 420 + 20 = 440, 440 + 20 = 460, 460 + 20 = 480, 480 + 20 = 500. The missing number is 480.

5. Answer: (2) 458
Explanation: An even number can be divided equally into two groups (ends in 0, 2, 4, 6, or 8). 458 ends in 8, so it is even. 347, 569, and 671 end in odd digits (7, 9, 1), so they are odd numbers.


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

6. Answer: Six hundred and seventy-three
Explanation: Write the number in words by place value: 600 = "six hundred", 70 = "seventy", 3 = "three". Join with "and" after hundred: "six hundred and seventy-three".
Marking: 1 mark for correct hundreds, 1 mark for correct tens and ones with proper hyphen/spelling.

7. Answer: 500
Explanation: In 592, the digit 5 is in the hundreds place. Value = 5 × 100 = 500.
Key concept: Value ≠ digit. The digit is 5; its value is 500.

8. Answer: 428, 482, 824, 842
Explanation: Compare hundreds first: 428 and 482 have 4 hundreds; 824 and 842 have 8 hundreds. So the 400s come before the 800s. Within the 400s: 428 (2 tens) < 482 (8 tens). Within the 800s: 824 (2 tens) < 842 (4 tens).

9. Answer: 600, 550
Explanation: The pattern decreases by 50 each time: 750 − 50 = 700, 700 − 50 = 650, 650 − 50 = 600, 600 − 50 = 550, 550 − 50 = 500.
Method: Find the difference between consecutive numbers to identify the rule.

10. Answer: 545
Explanation: Adding 200 means adding 2 hundreds. 345 + 200 = (300 + 200) + 40 + 5 = 500 + 40 + 5 = 545.
Mental strategy: Add the hundreds: 3 hundreds + 2 hundreds = 5 hundreds. Keep tens and ones the same.

11. Answer: 500
Explanation: Subtracting 300 means subtracting 3 hundreds. 800 − 300 = 5 hundreds = 500.
Mental strategy: 8 hundreds − 3 hundreds = 5 hundreds.

12. Answer: 357, 579
Explanation: Odd numbers end in 1, 3, 5, 7, or 9. Check each: 246 (ends in 6 → even), 357 (ends in 7 → odd), 468 (ends in 8 → even), 579 (ends in 9 → odd), 680 (ends in 0 → even). Circle 357 and 579.

13. Answer: 499
Explanation: 10 more than 489 means adding 10 (1 ten). 489 + 10 = 499. The tens digit increases from 8 to 9; hundreds and ones stay the same.

14. Answer: 632
Explanation: 100 less than 732 means subtracting 100 (1 hundred). 732 − 100 = 632. The hundreds digit decreases from 7 to 6; tens and ones stay the same.

15. Answer: 500
Explanation: In a number bond, the whole is the sum of the two parts. Whole = 800, Part 1 = 300. Missing part = Whole − Part 1 = 800 − 300 = 500.
Check: 300 + 500 = 800 ✓
Visual reference: The number bond diagram shows Whole (800) split into Part 1 (300) and Part 2 (?).


Section C: Word Problems (5 × 1 mark = 5 marks)

16. Equation: 456 + 200 = 656
Answer: 656 marbles
Explanation: "Altogether" means addition. Add the red marbles (456) and blue marbles (200). 456 + 200 = 656.

17. Equation: 680 − 300 = 380
Answer: 380 pages
Explanation: "Left to read" means subtraction. Total pages (680) minus pages read (300) = pages left. 680 − 300 = 380.

18. Answer: 500
Explanation: Counting in hundreds from 200: 1st = 200, 2nd = 300, 3rd = 400, 4th = 500. The 4th number is 500.

19. Answer: 574
Explanation:

  • Hundreds digit = 5 (given)
  • Tens digit = 5 + 2 = 7
  • Ones digit = 7 − 3 = 4
    Number = 574.
    Check: Hundreds=5, Tens=7 (2 more than 5 ✓), Ones=4 (3 less than 7 ✓).

20. Equation: 900 − 400 = 500
Answer: 500 girls
Explanation: Total students (900) minus boys (400) = girls. 900 − 400 = 500.
