Mathematics Primary 2 | Practice Paper: Numbers (Whole Numbers up to 1000)

Version 2 of 5

Section A: Place Value (10 marks)

1. What is the value of the digit 4 in 463?

• Answer: 400
• Marks: 2
• Working: The digit 4 is in the hundreds place. 4 hundreds = 400.
• Marking note: Award 2 marks for the correct answer. Award 0 marks for "4" (confusing digit with its value).

2. Write seven hundred and twenty-five in numerals.

• Answer: 725
• Marks: 2
• Working: 7 hundreds, 2 tens, 5 ones → 725.
• Marking note: Award 2 marks for 725. Common error: writing 70025 or 7205.

3. Which digit is in the tens place in 817?

• Answer: 1
• Marks: 2
• Working: 817 = 8 hundreds, 1 ten, 7 ones. The tens digit is 1.
• Marking note: Award 2 marks for the correct digit. Award 0 if the student writes "10" (value instead of digit).

4. Write 500 + 30 + 9 as a single number.

• Answer: 539
• Marks: 2
• Working: 500 + 30 + 9 = 539.
• Marking note: Award 2 marks for 539. Common error: 500309 or 5039.

5. What is the value of the digit 6 in 261?

• Answer: 60
• Marks: 2
• Working: The digit 6 is in the tens place. 6 tens = 60.
• Marking note: Award 2 marks for 60. Award 0 marks for "6" (confusing digit with its value).

Section B: Comparing and Ordering Numbers (8 marks)

6. Write >, <, or = in each box. (1 mark each)

(a) 345 < 354

• Working: Both have 3 hundreds. Compare tens: 4 tens < 5 tens. So 345 < 354.

(b) 700 > 699

• Working: 700 has 7 hundreds; 699 has 6 hundreds. 700 > 699.

(c) 128 = 128

• Working: Both numbers are identical.

(d) 876 > 786

• Working: Compare hundreds: 8 hundreds > 7 hundreds. So 876 > 786.

• Marking note: Award 1 mark per correct symbol. No partial credit.

7. Arrange from smallest to biggest: 523, 325, 532, 235

• Answer: 235, 325, 523, 532
• Marks: 2
• Working: Compare hundreds first: 235 (2 hundreds) is smallest, then 325 (3 hundreds), then 523 and 532 (both 5 hundreds). Between 523 and 532, compare tens: 2 tens < 3 tens, so 523 < 532.
• Marking note: Award 2 marks for all four in correct order. Award 1 mark if 2 are swapped but the rest are correct.

8. Smallest 3-digit number using digits 3, 7, and 1 (each used once).

• Answer: 137
• Marks: 2
• Working: To make the smallest number, put the smallest digit in the hundreds place (1), then the next smallest in the tens place (3), then the largest in the ones place (7). So: 137.
• Marking note: Award 2 marks for 137. Award 1 mark if the student uses all three digits but in a wrong order (e.g., 173).

Section C: Number Patterns (6 marks)

9. 200, 300, 400, _____, _____

• Answer: 500, 600
• Marks: 2
• Working: The pattern increases by 100 each time. 400 + 100 = 500, 500 + 100 = 600.
• Marking note: Award 2 marks for both correct. Award 1 mark if only one is correct.

10. 950, 900, 850, _____, _____

• Answer: 800, 750
• Marks: 2
• Working: The pattern decreases by 50 each time. 850 − 50 = 800, 800 − 50 = 750.
• Marking note: Award 2 marks for both correct. Award 1 mark if only one is correct.

11. 125, 150, 175, _____, _____

• Answer: 200, 225
• Marks: 2
• Working: The pattern increases by 25 each time. 175 + 25 = 200, 200 + 25 = 225.
• Marking note: Award 2 marks for both correct. Award 1 mark if only one is correct.

Section D: Odd and Even Numbers (6 marks)

12. Circle all the even numbers.

• Answer: 34, 68, 100 (circled)
• Marks: 2
• Working: Even numbers end in 0, 2, 4, 6, or 8. 34 ends in 4 (even), 57 ends in 7 (odd), 68 ends in 8 (even), 91 ends in 1 (odd), 100 ends in 0 (even), 43 ends in 3 (odd).
• Marking note: Award 2 marks if all three even numbers are circled and no odd numbers are circled. Award 1 mark if one even number is missed or one odd number is incorrectly circled.

13. Is 472 an odd or even number? Explain how you know.

• Answer: Even
• Explanation: 472 ends in 2. Numbers that end in 0, 2, 4, 6, or 8 are even numbers. Also, 472 can be divided equally into two groups: 236 + 236 = 472.
• Marks: 2
• Marking note: Award 1 mark for identifying "even" and 1 mark for a valid explanation (referring to the last digit or equal sharing into two groups).

14. Write two odd numbers between 200 and 210.

• Answer: 201 and 203 (other acceptable pairs: 201 & 205, 201 & 207, 201 & 209, 203 & 205, 203 & 207, 203 & 209, 205 & 207, 205 & 209, 207 & 209)
• Marks: 2
• Working: Odd numbers between 200 and 210 are: 201, 203, 205, 207, 209. Any two of these are acceptable.
• Marking note: Award 2 marks for any two correct odd numbers. Award 1 mark if only one is correct. Award 0 if an even number is given.
