Mathematics Primary 2 | Numbers (Whole Numbers up to 1000)

Version 3 of 5


Section A (10 marks)

1. What is the value of the digit 6 in 683?

  • Answer: 600
  • Working: The digit 6 is in the hundreds place. 6 hundreds = 600.
  • Marks: 2
  • Marking note: Award 2 marks for correct answer. Award 1 mark if student writes "6 hundreds" without the value 600 (partial understanding).

2. Write "four hundred and twenty-seven" in numerals.

  • Answer: 427
  • Working: 4 hundreds, 2 tens, 7 ones → 427
  • Marks: 2
  • Marking note: Award 2 marks for correct answer. Common mistake: writing 40027 or 400 27 (not understanding place value notation).

3. Arrange from smallest to biggest: 745, 574, 754, 475

  • Answer: 475, 574, 745, 754
  • Working: Compare hundreds first: 475 (4 hundreds) is smallest. Then 574 (5 hundreds). Between 745 and 754 (both 7 hundreds), compare tens: 4 tens < 5 tens, so 745 < 754.
  • Marks: 2
  • Marking note: Award 2 marks for all correct. Award 1 mark if 2–3 numbers are in correct position.

4. Find the missing numbers: 150, 200, 250, ______, ______

  • Answer: 300, 350
  • Working: The pattern increases by 50 each time. 250 + 50 = 300. 300 + 50 = 350.
  • Marks: 2
  • Marking note: Award 2 marks for both correct. Award 1 mark for one correct answer (if the pattern method is shown).

5. Is 368 odd or even? Explain how you know.

  • Answer: Even
  • Explanation: 368 ends in 8, which is an even number. Even numbers end in 0, 2, 4, 6, or 8. (Alternatively: 368 can be divided equally into two groups of 184.)
  • Marks: 2
  • Marking note: Award 1 mark for correct identification (even). Award 1 mark for a valid explanation. Accept any correct reasoning.

Section B (10 marks)

6. Which digit is in the tens place in 914?

  • Answer: 1
  • Working: 914 = 9 hundreds, 1 ten, 4 ones. The tens digit is 1.
  • Marks: 2
  • Marking note: Award 2 marks for correct answer. Common mistake: writing "10" instead of "1" (confusing digit with value).

7. Write 506 in expanded form.

  • Answer: 500 + 0 + 6 (or 500 + 6)
  • Working: 506 = 5 hundreds + 0 tens + 6 ones = 500 + 0 + 6
  • Marks: 2
  • Marking note: Award 2 marks for correct expanded form. Award 1 mark if student writes 500 + 6 (omitting the tens is acceptable at this level).

8. Fill in >, <, or =: 820 _______ 802

  • Answer: >
  • Working: Both numbers have 8 hundreds. Compare the tens: 2 tens > 0 tens. So 820 > 802.
  • Marks: 2
  • Marking note: Award 2 marks for correct symbol. Common mistake: students may look at the ones digit (0 vs 2) instead of the tens.

9. Count backwards: 900, 800, 700, ______, ______

  • Answer: 600, 500
  • Working: The pattern decreases by 100 each time. 700 − 100 = 600. 600 − 100 = 500.
  • Marks: 2
  • Marking note: Award 2 marks for both correct. Award 1 mark for one correct.

10. Tom has 235 stickers. He gets 100 more. How many now?

  • Answer: 335
  • Working: 235 + 100 = 335. Adding 100 increases the hundreds digit by 1 (2 hundreds → 3 hundreds).
  • Marks: 2
  • Marking note: Award 2 marks for correct answer. Award 1 mark if working is shown but final answer has a minor arithmetic error.

Section C (10 marks)

11. Look at the number 438.

  • (a) How many hundreds? Answer: 4
  • (b) How many ones? Answer: 8
  • Working: 438 = 4 hundreds, 3 tens, 8 ones.
  • Marks: 2 (1 mark per part)
  • Marking note: Award 1 mark for each correct part.

12. Numbers: 612, 261, 126, 621

  • (a) Smallest: Answer: 126
  • (b) Biggest: Answer: 621
  • Working: Compare hundreds: 126 (1 hundred) is smallest. Among 612 and 621 (both 6 hundreds), compare tens: 1 ten < 2 tens, so 621 is biggest.
  • Marks: 2 (1 mark per part)
  • Marking note: Award 1 mark for each correct part.

13. Find the missing numbers: 100, 200, ______, 400, ______, 600

  • Answer: 300, 500
  • Working: The pattern increases by 100 each time. 200 + 100 = 300. 400 + 100 = 500.
  • Marks: 2
  • Marking note: Award 2 marks for both correct. Award 1 mark for one correct.

14. A shop has 560 apples. It sells 300. How many left?

  • Answer: 260
  • Working: 560 − 300 = 260. Subtracting 300 decreases the hundreds digit by 3 (5 hundreds → 2 hundreds). 60 ones remain.
  • Marks: 2
  • Marking note: Award 2 marks for correct answer with or without working. Award 1 mark for correct method with minor error.

15. Write all the even numbers between 70 and 80.

  • Answer: 72, 74, 76, 78
  • Working: Even numbers end in 0, 2, 4, 6, or 8. Between 70 and 80 (not including 70 and 80): 72, 74, 76, 78.
  • Marks: 2
  • Marking note: Award 2 marks for all four correct. Award 1 mark for 2–3 correct numbers. Do not penalise if 70 or 80 is included (accept the student's interpretation of "between").
