Answer Key and Marking Notes

Section A: Counting and Number Recognition (Questions 1–5)

Each question carries 1 mark.

1. Answer: 20 stars
Working: Count each star one by one: 1, 2, 3, ... up to 20.
Marking Note: Award 1 mark for the correct answer. Common mistake: skipping a star or double-counting.

2. Answer: 25 apples
Working: There are 5 rows of 5 apples each. 5 × 5 = 25. Alternatively, count by fives: 5, 10, 15, 20, 25.
Marking Note: Award 1 mark for the correct answer.

3. Answer: 50
Working: The number after 49 is 49 + 1 = 50.
Marking Note: Award 1 mark for the correct answer. Common mistake: writing 48 (confusing "after" with "before").

4. Answer: 69
Working: The number before 70 is 70 − 1 = 69.
Marking Note: Award 1 mark for the correct answer.

5. Answer: 50, 60
Working: Counting in tens means adding 10 each time. 40 + 10 = 50, 50 + 10 = 60.
Marking Note: Award 1 mark only if both answers are correct.

Section B: Place Value (Questions 6–10)

Each question carries 2 marks.

6. Answer: tens; ones
Working: In 52, the digit 5 is in the tens place (left) and the digit 2 is in the ones place (right).
Marking Note: Award 1 mark for each correct answer. Common mistake: confusing the position of tens and ones.

7. Answer: 70
Working: The digit 7 is in the tens place in 73. The value of 7 tens is 70.
Marking Note: Award 2 marks for the correct answer. Award 1 mark if the student writes "7" (confusing digit with value).

8. Answer: 64
Working: 6 tens = 60, and 4 ones = 4. 60 + 4 = 64.
Marking Note: Award 2 marks for the correct answer.

Marking Note: Award 2 marks for a correct drawing. Award 1 mark if the student shows the right idea but the drawing is unclear.

10. Answer: 8 tens + 4 ones
Working: 84 = 80 + 4 = 8 tens + 4 ones.
Marking Note: Award 1 mark for each correct blank.

Section C: Comparing and Ordering Numbers (Questions 11–15)

Each question carries 2 marks.

11. Answer: 54
Working: Compare the tens digit: 5 tens (in 54) is more than 4 tens (in 45). So 54 is bigger.
Marking Note: Award 2 marks for the correct answer. Award 1 mark if the student shows correct comparison reasoning but makes a calculation error.

12. Answer: 83
Working: Both numbers have 8 tens. Compare the ones: 3 ones (in 83) is less than 8 ones (in 88). So 83 is smaller.
Marking Note: Award 2 marks for the correct answer.

13. Answer: 29, 51, 67, 84
Working: Compare the tens digits: 2 < 5 < 6 < 8. So the order from smallest to biggest is 29, 51, 67, 84.
Marking Note: Award 2 marks if all four numbers are in the correct order. Award 1 mark if at least two numbers are in the correct position.

14. Answer: >
Working: 76 has 7 tens and 67 has 6 tens. 7 tens > 6 tens, so 76 > 67.
Marking Note: Award 2 marks for the correct symbol. Common mistake: confusing > and <.

15. Answer: Lily
Working: Compare 38 and 43. 4 tens (in 43) is more than 3 tens (in 38). So Lily has more stickers.
Marking Note: Award 2 marks for the correct answer with or without working. Award 1 mark if the student writes "43" without naming Lily.
