Total Marks: 40

Section A (10 marks)

1. 7 (1 mark)
Teaching note: Place values from right: ones (2), tens (9), hundreds (3), thousands (7), ten thousands (4). The digit in thousands place is 7.

2. 600 (1 mark)
Teaching note: 81,604 → digit 6 is in hundreds place, so it stands for 6 × 100 = 600. Common mistake: saying 6 or 60.

3. 62,015 (1 mark)
Teaching note: "Sixty-two thousand" = 62,000; "and fifteen" = 15 → 62,015.

4. 38,000 (1 mark)
Working: 38,471 → hundreds digit is 4, so round down to 38,000.

5. 72,900 (1 mark)
Working: 72,938 → tens digit is 3, round down → 72,900.

6. 36,023 (1 mark)
Working: 12,345 + 23,678 = 36,023.

7. 30,124 (1 mark)
Working: 40,000 − 9,876 = 30,124.

8. 9,642 (1 mark)
Working: 3,214 × 3 = 9,642.

9. 2,160 (1 mark)
Working: 8,640 ÷ 4 = 2,160.

10. 1, 2, 3, 6, 9, 18 (1 mark)
Teaching note: Factors are numbers that divide 18 with no remainder. Common mistake: missing 1 and 18.

Section B (12 marks)

11. (2 marks)

24,815 rounded to nearest ten thousand = 20,000 (1 mark)
19,240 rounded to nearest ten thousand = 20,000 (0.5 mark)
Estimated difference = 20,000 − 20,000 = 0 (0.5 mark)
Teaching note: Both round to same ten thousand, so estimated difference is 0.

12. (2 marks)

Number 53,7_2 rounded to hundred = 53,700 means the tens digit (already 0 from 53,7_2? Actually hundreds digit is 7, tens digit is the blank? Wait: 53,7_2 → thousands=3, hundreds=7, tens=_, ones=2. Rounding to hundred looks at tens digit. To round to 53,700, tens digit must be 0–4. So possible ones digit is 0,1,2,3,4? No: ones is fixed as 2. The blank is tens. So tens can be 0,1,2,3,4.) (1 mark for possible digits 0–4)
Explanation: tens digit 0–4 rounds down to 53,700. (1 mark)
