TuitionGoWhere Practice Paper — Answer Key
Subject: Mathematics | Level: Primary 2 | Version: 4 of 5
Total Marks: 50
Section A: Multiple Choice (10 marks)
| Question | Answer | Explanation |
|---|---|---|
| 1 | C) 600 | The digit 6 is in the hundreds place. In place value, each position has a value: hundreds = ×100, tens = ×10, ones = ×1. So 6 × 100 = 600. Common mistake: Choosing B (60) by confusing tens and hundreds place. |
| 2 | A) 309 | Compare hundreds first: all have 3, 3, 9, 9. Then compare tens: 0 < 9, so 309 and 390 are smaller than 903 and 930. Finally 0 < 9 in the ones place comparison of 309 vs 390. |
| 3 | B) 792 | Standard addition: 527 + 265. Ones: 7+5=12 (write 2, carry 1). Tens: 2+6+1=9. Hundreds: 5+2=7. Result: 792. |
| 4 | B) 600 | Pattern: counting up by 50s each time. 450 + 50 = 500, 500 + 50 = 550, 550 + 50 = 600, 600 + 50 = 650. ✓ |
| 5 | B) 687 | "200 more than" means add 200: 487 + 200 = 687. The hundreds digit increases by 2. |
| 6 | A) 453 | Subtraction with regrouping: 800 – 347. Ones: 0–7 needs regrouping → 10–7=3. Tens: 9–4=5 (after regrouping). Hundreds: 7–3=4. Result: 453. |
| 7 | B) 3 | In 935: 9 is hundreds, 3 is tens, 5 is ones. The tens place is the middle digit. |
| 8 | A) 278, 287, 728, 872 | Compare hundreds: 2, 2, 7, 8. So 278 and 287 come before 728 and 872. Compare 278 vs 287: 78 < 87. Compare 728 vs 872: 728 < 872. |
| 9 | C) 703 | "100 less than" means subtract 100: 803 – 100 = 703. The hundreds digit decreases by 1. |
| 10 | C) 600 + 20 + 4 | Expanded form shows each digit's value: 624 = 600 (6 hundreds) + 20 (2 tens) + 4 (4 ones). |
Section A Total: 10 marks
Section B: Short Answer (24 marks)
11. (a) 673 [1 mark]
- "Six hundred" = 600, "seventy-three" = 73. Together: 600 + 73 = 673.
11. (b) nine hundred and five [1 mark]
- 905: 9 hundreds, 0 tens, 5 ones. In words, we say "nine hundred and five." Note: "and" is used before the tens/ones part in Singapore style.
12. (a) 50 [1 mark]
- The digit 5 in 358 is in the tens place. Value = 5 × 10 = 50.
12. (b) 80 [1 mark]
- The digit 8 in 784 is in the tens place. Value = 8 × 10 = 80.
13. (a) < (or 456 < 465) [1 mark]
- Hundreds are equal (4 = 4). Compare tens: 5 < 6. So 456 < 465.
13. (b) = (or 803 = 800 + 3) [1 mark]
- 800 + 3 = 803. The expanded form matches the number exactly. This tests understanding that 803 = 800 + 0 + 3.
14. (a) 390, 395 [2 marks]
- Pattern: counting up by 5s. 385 + 5 = 390, 390 + 5 = 395.
- Marking: 1 mark for each correct number.
14. (b) 750, 700 [2 marks]
- Pattern: counting down by 50s. 800 – 50 = 750, 750 – 50 = 700.
- Marking: 1 mark for each correct number.
15. (a) 277 [1 mark]
- Mental method: 247 + 30 = 247 + 10 + 10 + 10 = 277. Or: add tens only: 24 tens + 3 tens = 27 tens, so 277.
15. (b) 258 [1 mark]
- Mental method: 658 – 400 = subtract 4 hundreds from 6 hundreds = 2 hundreds, with tens and ones unchanged. Result: 258.
16. 473 stickers [2 marks]
- Working: Sarah has 128 more than David.
345 + 128 = ?
Ones: 5 + 8 = 13 (write 3, carry 1)
Tens: 4 + 2 + 1 = 7
Hundreds: 3 + 1 = 4
Answer: 473 stickers - Marking: 1 mark for correct method, 1 mark for correct answer. Accept 345 + 128 shown even if arithmetic error (method mark).
17. 88 buns [3 marks]
- Working (Method 1 - total sold first):
Total sold = 267 + 145 = 412
Left = 500 – 412 = 88 - Working (Method 2 - step by step):
After morning: 500 – 267 = 233
After afternoon: 233 – 145 = 88 - Marking: 1 mark for finding total sold or first step, 1 mark for correct subtraction method, 1 mark for correct final answer.
18. 57 pencils [3 marks]
- Working:
Total pencils = 3 × 24 = 72 (or 24 + 24 + 24 = 72)
Left after giving away: 72 – 15 = 57 - Marking: 1 mark for finding total pencils (3 × 24), 1 mark for subtracting 15, 1 mark for correct final answer.
- Common error: Forgetting to multiply first (e.g., using 24 – 15 = 9). This gets 0 for first mark but may get method marks if subsequent steps follow logically.
Section B Total: 24 marks
Section C: Word Problems and Application (16 marks)
19. Place value chart question (visual-based)
Visual reference: Place value chart shows 4 hundreds flats, 3 tens rods, 7 ones cubes. Expected number: 437.
(a) 437 [1 mark]
- 4 hundreds + 3 tens + 7 ones = 400 + 30 + 7 = 437.
(b) 537 [2 marks]
- Working: 100 more than 437 = 437 + 100 = 537.
- When we add 100, only the hundreds digit changes: 4 becomes 5.
- Marking: 1 mark for correct method (adding 100), 1 mark for correct answer.
(c) 743 [1 mark]
- To make the biggest number, put the largest digit (7) in the hundreds place, then next largest (4) in tens, smallest (3) in ones: 743.
(d) 347 [1 mark]
- To make the smallest number, put the smallest digit (3) in the hundreds place, then next smallest (4) in tens, largest (7) in ones: 347.
- Common error: 374 (forgetting to check tens vs ones ordering).
19. Total: 6 marks
20. Table-based problem
Visual reference: Table with Monday: 156, Tuesday: 203, Friday: 189. Wednesday and Thursday blank.
(a) 203 books [2 marks]
- Working: Wednesday = Monday + 47 = 156 + 47
156 + 47 = 156 + 40 + 7 = 196 + 7 = 203 - Marking: 1 mark for correct method (adding 47 to 156), 1 mark for correct answer.
- Note: Coincidentally equals Tuesday's value, but this is correct.
(b) 94 books [3 marks]
- Working:
Known total = 156 + 203 + 203 + 189 = 751
Thursday = 845 – 751 = 94 - Or:
Monday + Tuesday + Wednesday + Friday = 156 + 203 + 203 + 189 = 751
Thursday = 845 – 751 = 94 - Marking: 1 mark for summing known values correctly, 1 mark for subtracting from total, 1 mark for correct final answer.
- Accept alternative: 845 – 156 – 203 – 203 – 189 step-by-step.
(c) Tuesday [1 mark for correct day], with explanation [1 mark]
- Tuesday (or Wednesday — they tie at 203).
- Explanation mark: Must state comparison without calculation, e.g., "Tuesday has 2 hundreds while others have 1 hundred, and Wednesday equals Tuesday." Or "203 and 203 are the biggest because they both have 2 in the hundreds place while the others have 1."
- Must explicitly mention hundreds place comparison or digit 2 vs digit 1 to get explanation mark.
(d) 200 [1 mark]
- 203 to nearest ten: look at ones digit 3. Since 3 < 5, round down to 200.
- Rule: If ones digit is 0–4, round down. If 5–9, round up.

Marking Summary & Common Issues
| Issue | Guidance |
|---|---|
| Reversed digits (e.g., 673 → 637) | Check place value understanding; suggest base-ten block practice |
| Expanded form errors | Reinforce: each digit × its place value, not just digits added |
| Subtraction regrouping errors | Practice "borrowing across zero" (e.g., 800 – 347) |
| "More than" vs "less than" | Encourage underlining key words; test with smaller numbers |
| Word problem setup | Ensure students write number sentence before calculating |
| Nearest ten rounding | Drill: "Look at the ones digit, 4 or less let it rest, 5 or more raise the score" |
