TuitionGoWhere Exam Practice (AI) - Mathematics Primary 3 Answer Key

Paper: SA2 Practice Paper (Version 5 of 5)
Total Marks: 50

Section A (20 marks)

1. 8 (2 marks)
Teaching note: Place value from right: ones (7), tens (2), hundreds (8), thousands (4). The hundreds place digit is 8.
Common mistake: saying 800 instead of 8 — question asks for the digit, not its value.

2. 6000 (2 marks)
Teaching note: Digit 6 is in the thousands place, so its value is 6 × 1000 = 6000.
Common mistake: writing 6 (the digit) instead of 6000 (the value).

3. 3952 (2 marks)
Teaching note: Compare thousands (same 3), hundreds (9 vs 9), tens (5 vs 4). 5 > 4 so 3952 > 3948.

4. 2009, 2049, 2094, 2940 (2 marks)
Teaching note: Ascending = smallest to largest. Compare place values: all have 2 thousand; hundreds: 0,0,0,9 → 2940 last; then 2009 < 2049 < 2094.

5. 3800 (2 marks)
Teaching note: Rounding to nearest hundred: look at tens digit (6). Since 6 ≥ 5, round up hundreds from 7 to 8 → 3800.

6. 1110 (2 marks)
Teaching note: Pattern increases by 30 each step (1050−1020=30, 1080−1050=30). 1080+30=1110. Check: 1110+30=1140 ✓.

7. 7341 (2 marks)
Teaching note: seven thousand = 7000, three hundred = 300, forty = 40, one = 1. 7000+300+40+1 = 7341.

8. 1037 (2 marks)
Teaching note: Smallest 4-digit using 3,0,7,1: put smallest non-zero digit (1) in thousands, then 0 in hundreds, then 3, then 7 → 1037.

9. 6000 (2 marks)
Teaching note: Rounding to nearest thousand: look at hundreds digit (8). 8 ≥ 5, round up → 6000.

10. 8 (2 marks)
Teaching note: Difference = 5000 − 4992 = 8.

Section B (18 marks)

11. 4843 students (3 marks)
Working: 2456 + 2387
= 2456 + 2000 + 300 + 80 + 7
= 4456 + 387 = 4843
Marking: 1 mark for correct operation, 2 marks for correct sum.

12. 2001 stickers (3 marks)
Working: Total given = 1576 + 1243 = 2819
Left = 4820 − 2819 = 2001
Marking: 1 mark addition, 1 mark subtraction, 1 mark final answer.

13. 4 (3 marks)
Teaching note: 6_45 between 6345 and 6545 means tens digit must be 4 (6345 < 6445 < 6545).
Marking: 1 mark understanding range, 2 marks correct digit.

14. 4000, 4500 (3 marks)
Teaching note: Constant difference 500. 3500+500=4000, 4000+500=4500.
Marking: 1 mark each correct number.

15. Nearest ten: 7500; nearest hundred: 7500; nearest thousand: 7000 (3 marks)
Working:

Ten: ones digit 9 ≥5 → 7499 → 7500
Hundred: tens digit 9 ≥5 → 7500
Thousand: hundreds digit 4 <5 → 7000
Marking: 1 mark each.

16. 3425, three thousand four hundred twenty-five (3 marks)
Working: 3×1000=3000, 4×100=400, 2×10=20, 5×1=5. Total = 3425.
Marking: 1 mark numerals, 2 marks words.

Section C (12 marks)

17. 3033 stamps (3 marks)
Working: Brother = 1287 + 459 = 1746
Altogether = 1287 + 1746 = 3033
Marking: 1 mark brother's count, 2 marks total.

18. 435 books (3 marks)
Working: 3421 − 2986 = 435
Marking: 1 mark operation, 2 marks answer.

19. 3A, 3C, 3B (3 marks)
Teaching note: 3128 > 3056 > 2974.

2517 ÷ 7 = 359 R 4 (since 7×359=2513, 2517−2513=4)
Marking: 1 mark storage, 1 mark quotient, 1 mark remainder.
