TuitionGoWhere Practice Paper — Mathematics Primary 3 (Answer Key)

Version: 3
Total Marks: 40

Section A Answers (10 marks)

1. 3
Teaching note: Place values from right: ones (2), tens (8), hundreds (3), thousands (6). Hundreds digit = 3.

2. 5000
Teaching note: 5 is in thousands place, so value = 5 × 1000 = 5000. Common mistake: writing "5" instead of its place value.

3. 2475, 2457, 2745, 2754 → correct order: 2457, 2475, 2745, 2754
Teaching note: Compare thousands (all 2), then hundreds: 4 < 7, so 24xx first. Among 2457 and 2475, tens 5 < 7.

4. 4098
Teaching note: Compare thousands: 3xxx < 4xxx, so 4098 or 4009. Then hundreds: 0 vs 0, tens 9 > 0 → 4098.

5. 3600
Teaching note: Hundreds digit 6, tens digit 4 (<5) → round down to 3600.

6. 8000
Teaching note: Thousands digit 7, hundreds digit 8 (≥5) → round up to 8000.

7. 2400, 2500
Teaching note: Pattern +100 each. 2300 + 100 = 2400, +100 = 2500.

8. 4850, 4800
Teaching note: Pattern −50 each. 4900 − 50 = 4850, −50 = 4800.

9. 7234
Teaching note: Seven thousand = 7000, two hundred = 200, thirty = 30, four = 4 → 7234.

10. Thousands
Teaching note: 8085 → ones 5, tens 8, hundreds 0, thousands 8. Digit 8 (leftmost) is thousands place.

Section B Answers (12 marks)

11. Digit 7; value = 700. (2 marks: 1 for digit, 1 for value)
Working: 3726 → hundreds place is 7. Value = 7 × 100 = 700.

12. 2910, 2880, 2840, 2795 (2 marks)
Working: Compare: 2910 highest (hundreds 9), then 2880 (8, tens 8), 2840 (8, tens 4), 2795 lowest.

13. 6450 (2 marks)
Working: Round to nearest ten: ones digit 3 (<5) → 6450.

14. 5000 (2 marks)
Working: Thousands 4, hundreds 5 (≥5) → round up to 5000.

15. 1264, 1274 (2 marks)
Working: +10 each: 1254 + 10 = 1264, +10 = 1274.

16. Day 3 (1290) (2 marks)
Working: 1365, 1420, 1290 → smallest is 1290 (Day 3).

Section C Answers (18 marks)

17. Zone digit 5, value 5000. (2 marks)
Working: 5184 → thousands = 5. Value = 5 × 1000 = 5000.

18. Nearest hundred: 3000; nearest thousand: 3000. (2 marks: 1 each)
Working: 2956 → hundreds digit 9, tens 5 ≥5 → 3000. Thousands 2, hundreds 9 ≥5 → 3000.

19. 7700, 7600 (2 marks)
Working: −100 pattern: 7800 − 100 = 7700, −100 = 7600.

20. (3 marks: 2 for order, 1 for gap)
Order: 3C 2874, 3A 2847, 3B 2784.
Highest needs: 3000 − 2874 = 126 more.
Working: 3000 − 2874 = 126.

21. (3 marks: 1 floor, 1 unit, 1 rounding)
Floor = 6 (hundreds), Unit = 2 (tens). Round 4625 → nearest hundred: 4600.
Working: 4625 → hundreds 6, tens 2 (<5) → 4600.

22. (3 marks: 1 next two, 2 explanation)
Correct next: 1750, 2000. Student wrong.
Working: Pattern +250: 1500 + 250 = 1750, +250 = 2000. Student's 1700 (+200) and 1950 (+250) inconsistent.
