Level: Primary 4
Total Marks: 40

Teaching notes are provided for each question. This paper is syllabus-first; no past-year exam evidence was used.

Section A: Place Value and Writing Numbers

1. [1 mark]
Answer: 3
Teaching: In 73,418, the places from right are ones (8), tens (1), hundreds (4), thousands (3), ten thousands (7). The digit in thousands place is 3.
Common mistake: Picking 7 (ten thousands) instead.

2. [1 mark]
Answer: 6,000 (six thousand)
Teaching: Digit 6 is in the thousands place (56,209 → 6 is thousands), so it stands for 6 × 1,000 = 6,000.
Note: "stand for" means its place value amount.

3. [2 marks]
Answer: 89,027
Marking: 1 mark for correct digits, 1 mark for correct comma placement.
Teaching: eighty-nine thousand = 89,000; twenty-seven = 27 → 89,027.
Common mistake: Writing 89,207 (confusing twenty-seven with two hundred seven).

4. [1 mark]
Answer: 100 (one hundred)
Teaching: In 90,153, digit 1 is in hundreds place → 1 × 100 = 100.

5. [1 mark]
Answer: 48,000
Teaching: To round to nearest thousand, look at hundreds digit (8 in 47,862). Since 8 ≥ 5, round up: 47,000 → 48,000.

Section B: Rounding and Number Patterns

6. [1 mark]
Answer: 12,300
Teaching: Hundreds digit is 3 (12,349); tens digit 4 < 5, so keep hundreds same → 12,300.

7. [1 mark]
Answer: (b) 5,475
Teaching: Numbers rounding to nearest ten = 5,470 must be from 5,465 to 5,474. Only 5,475 is wrong? Wait: 5,475 rounds to 5,480. Actually correct choices: 5,464→5,460; 5,475→5,480; 5,481→5,480; 5,469→5,470. So (d) 5,469 is correct.
Correction: Answer is (d) 5,469.
Teaching: Nearest ten: look at ones digit. 5,469 ones=9 ≥5 → round up to 5,470.

8. [2 marks]
Answer: 25,000 and 25,500
Marking: 1 mark each.
Teaching: Pattern adds 500 each step: 23,500 + 500 = 24,000; +500 = 24,500; next +500 = 25,000; +500 = 25,500.

9. [1 mark]
Answer: 100,000
Teaching: Nearest ten thousand: look at thousands digit (9 in 99,555). 9 ≥ 5 → round up to 100,000.

10. [2 marks]
Answer: digit 3; value 30,000
Marking: 1 mark digit, 1 mark value.
Teaching: 38,472 → ten thousands digit is 3 (leftmost), value = 3 × 10,000 = 30,000.

Section C: Operations and Problem Solving

11. [1 mark]
Answer: 9,111
Working: 3,214 + 5,897 = 9,111.

12. [2 marks]
Answer: 6,023 stickers
Working: 2,345 + 3,678 = 6,023.
Marking: 1 mark for operation, 1 mark for correct answer.

13. [2 marks]
Answer: 12,708
Working:
4,236 × 3 = (4,000×3) + (200×3) + (30×3) + (6×3)
= 12,000 + 600 + 90 + 18 = 12,708.
Marking: 1 mark method, 1 mark answer.

14. [2 marks]
Answer: 2,118
Working: 8,472 ÷ 4
8,000÷4=2,000; 400÷4=100; 70÷4=17 r2; 32÷4=8 → 2,000+100+17+8 = 2,118.
Check: 2,118 × 4 = 8,472.

15. [2 marks]
Answer: 8,651 marbles
Working: 12,500 − 3,849 = 8,651.

16. [2 marks]
Answer: 483 boxes
Working: 2,415 ÷ 5 = 483.
Marking: 1 mark division, 1 mark answer.

17. [2 marks]
Answer: 67,200; estimate 80,100
Working: 67,234 → hundreds digit 2 <5 → 67,200. Estimate: 67,200 + 12,899 = 80,099 ≈ 80,100 (if strict sum: 80,099). Accept 80,099 or 80,100.
Marking: 1 mark rounding, 1 mark estimate.

18. [3 marks]
Answer: 59,000; difference 33,153; "thirty-three thousand one hundred and fifty-three"
Working:
Round 58,935 to nearest thousand: hundreds=9 ≥5 → 59,000.
Difference: 59,000 − 25,847 = 33,153.
Words: thirty-three thousand one hundred and fifty-three.
Marking: 1 mark round, 1 mark subtract, 1 mark words.

19. [3 marks]
Answer: 28,353 passengers
Working: 7,842 + 6,913 = 14,755; +5,478 = 20,233; +8,120 = 28,353.
Marking: 1 mark partial sums, 2 marks final.

20. [3 marks]
Answer: 1,599 books
Working: 3 × 1,245 = 3,735; 3,735 − 2,136 = 1,599.
Marking: 1 mark multiply, 1 mark subtract, 1 mark answer.
