TuitionGoWhere Practice Paper - Mathematics Primary 4 (Answer Key)

Version: 2 of 5
Total Marks: 50

Section A (10 marks)

1. 3 (1 mark)
Teaching note: Place value from right: ones (8), tens (1), hundreds (4), thousands (3), ten thousands (7). The digit in thousands place is 3.

2. 6,000 (1 mark)
Teaching note: In 56,092, digit 6 is in the thousands place, so it stands for 6 × 1,000 = 6,000. Common mistake: writing 600 (hundreds) or 60 (tens).

3. 89,007 (1 mark)
Teaching note: "Eighty-nine thousand" = 89,000; "and seven" = 7. Combined: 89,007. Note: no "and" before hundreds in Singapore numeral writing for whole numbers.

4. 35,000 (1 mark)
Teaching note: Rounding to nearest thousand: look at hundreds digit (5). Since 5 ≥ 5, round up: 34,562 → 35,000.

5. 71,100 (1 mark)
Teaching note: Nearest hundred: tens digit is 4 (<5), so round down: 71,049 → 71,000? Wait, tens digit is 4, hundreds digit is 0, number is 71,049. Hundreds digit = 0, tens = 4, so round down to 71,000. Correction: 71,049 rounded to nearest hundred is 71,000 (since 49 < 50).
Marking: award 1 mark for 71,000.

6. (c) 45,683 (1 mark)
Teaching note: Rounding to nearest ten: ones digit decides. 45,680 means original was 45,675–45,684. Only 45,683 fits. (a) 45,674→45,670; (b) 45,685→45,690; (d) 45,675→45,680 also fits but typically one option; both c and d valid, but given choices, c is listed. Accept 45,675 or 45,683; in MCQ we use c as intended.)

7. 8,082 (1 mark)
Working: 4,217 + 3,865 = 4,000+3,000=7,000; 217+865=1,082; total 8,082.

8. 19,224 (1 mark)
Working: 3,204 × 6 = (3,000×6)+(200×6)+(4×6)=18,000+1,200+24=19,224.

9. 2,108 (1 mark)
Working: 8,432 ÷ 4 = 2,000 rem 432; 432 ÷ 4 = 108; total 2,108.

10. 1, 2, 3, 6, 9, 18 (1 mark)
Teaching note: Factors are numbers that divide 18 with no remainder. Pairs: 1×18, 2×9, 3×6.

Marking: 1 mark for aligned addition, 1 for correct sum.

12. 70,000; estimate 90,000 (2 marks: 1 each)
Working: 67,834 → ten thousands digit 6, thousands 7 ≥5 → round up to 70,000. Estimate: 70,000 + 21,489 ≈ 91,489 or using rounded 21,489? Task says use rounded number for 67,834 only: 70,000 + 21,489 = 91,489 ≈ 91,000. If estimate both: 70,000+21,000=91,000. Accept 91,489 or 91,000 as estimate.
Marking: 1 for 70,000, 1 for reasonable estimate.

13. 7,350 books (2 marks)
Working: 2,450 × 3 = 7,350.
Marking: 1 for method, 1 for answer.
