Answers

TuitionGoWhere Practice Paper — Answer Key

Mathematics Primary 3 | Whole Numbers | Version 5 of 5

Section A: Multiple Choice (10 marks)

1. What is the value of the digit 6 in the number 6,384?

Answer: D (6,000)
The digit 6 is in the thousands place. Value = 6 × 1,000 = 6,000.
Common mistake: Choosing A (6) — this is the digit itself, not its value.

2. Which digit is in the hundreds place in the number 4,725?

Answer: B (7)
Place values in 4,725: 4 (thousands), 7 (hundreds), 2 (tens), 5 (ones).
Common mistake: Choosing A — confusing thousands with hundreds.

3. Write three thousand and fifty-two in numerals.

Answer: B (3,052)
Three thousand = 3,000; fifty = 50; two = 2. Combined: 3,000 + 50 + 2 = 3,052.
Common mistake: Choosing A (3,520) — confusing "fifty-two" with "five hundred and twenty."

4. Which of the following is the smallest number?

Answer: C (5,234)
All numbers start with 5 (thousands). Compare hundreds: 2 < 3 < 4. So 5,234 is smallest.
Method: Compare digit by digit from left to right.

5. Round 4,678 to the nearest hundred.

Answer: C (4,700)
The tens digit is 7 (≥ 5), so round up: 4,678 → 4,700.
Common mistake: Choosing A (4,600) — rounding down when the tens digit is 7.

6. What is 2,000 + 300 + 50 + 7 in standard form?

Answer: A (2,357)
2,000 + 300 + 50 + 7 = 2,357.
Method: Add place values from largest to smallest.

7. Which number is even?

Answer: C (6,842)
An even number ends in 0, 2, 4, 6, or 8. Only 6,842 ends in 2.
Common mistake: Choosing an odd number — check the ones digit.

8. Arrange in ascending order: 3,456 | 3,546 | 3,465 | 3,564

Answer: A (3,456, 3,465, 3,546, 3,564)
All start with 3 (thousands) and 4 or 5 (hundreds). Compare:
- 3,456 and 3,465 both have 4 hundreds → compare tens: 5 < 6 → 3,456 < 3,465
- 3,546 and 3,564 both have 5 hundreds → compare tens: 4 < 6 → 3,546 < 3,564
Order: 3,456 < 3,465 < 3,546 < 3,564

9. What is the missing number in the pattern: 2,100, 2,200, 2,300, _____, 2,500?

Answer: B (2,400)
Pattern: each number increases by 100. 2,300 + 100 = 2,400.
Common mistake: Choosing A (2,350) — adding 50 instead of 100.

10. A school has 3,847 students. What is this number rounded to the nearest ten?

Answer: C (3,850)
The ones digit is 7 (≥ 5), so round up: 3,847 → 3,850.
Common mistake: Choosing B (3,840) — rounding down when ones digit is 7.

Section B: Short Answer (20 marks)

11. Write 7,093 in words. (2 marks)

Answer: Seven thousand and ninety-three
Marking: Award 2 marks for correct answer. Award 1 mark if "seven thousand" is correct but the rest is wrong.
Common mistake: Writing "seven thousand nine hundred and three" — the hundreds digit is 0, so it is "and ninety-three," not "nine hundred."

12. What is the value of each digit in 5,618? (2 marks)

Digit	Value
5	5,000
6	600
1	10
8	8

Marking: Award ½ mark per correct value (total 2 marks).
Method: Multiply each digit by its place value (thousands = ×1,000, hundreds = ×100, tens = ×10, ones = ×1).

13. Compare 4,285 and 4,258 using >, <, or =. (2 marks)

Answer: 4,285 > 4,258
Working: Both have 4 thousands and 2 hundreds. Compare tens: 8 > 5, so 4,285 is greater.
Marking: Award 2 marks for correct symbol with or without working. Award 1 mark for correct symbol only if working is missing.

14. Library books table. (3 marks)

Library	Number of Books
North	6,342
South	6,234
East	6,432
West	6,324

(a) Most books: East (6,432)

Working: Compare hundreds: 4 > 3 > 2. East has 4 hundreds → most.

(b) Fewest books: South (6,234)

Working: South has 2 hundreds → fewest.

Working: 6,432 > 6,342 > 6,324 > 6,234
Marking: 1 mark each for (a), (b), and (c).

15. Complete the number pattern. (3 marks)

Pattern: 8,760, 8,770, 8,780, 8,790, 8,800, 8,810
Working: Each number increases by 10.
- 8,780 + 10 = 8,790
- 8,790 + 10 = 8,800
- 8,800 + 10 = 8,810
Marking: 1 mark per correct number.
Common mistake: Adding 100 instead of 10 — check the pattern carefully.

16. Round each number to the nearest hundred. (3 marks)

Number	Rounded to nearest hundred
2,349	2,300
5,650	5,700
8,175	8,200

Working:
- 2,349: tens digit is 4 (< 5) → round down → 2,300
- 5,650: tens digit is 5 (≥ 5) → round up → 5,700
- 8,175: tens digit is 7 (≥ 5) → round up → 8,200
Marking: 1 mark per correct answer.
Common mistake: For 5,650, some students round down. When the tens digit is exactly 5, always round up.

Section C: Structured / Word Problems (10 marks)

17. Total parking spaces on Level 1 and Level 2. (2 marks)

Answer: 8,403 parking spaces
Working:
```
  4,506
+ 3,897
-------
  8,403
```
- Ones: 6 + 7 = 13 → write 3, carry 1
- Tens: 0 + 9 + 1 = 10 → write 0, carry 1
- Hundreds: 5 + 8 + 1 = 14 → write 4, carry 1
- Thousands: 4 + 3 + 1 = 8
Marking: 1 mark for correct working, 1 mark for correct answer.

18. Charity drive collections. (3 marks)

(a) Total collected: $6,125

Working:
```
  2,475
+ 3,650
-------
  6,125
```
- Ones: 5 + 0 = 5
- Tens: 7 + 5 = 12 → write 2, carry 1
- Hundreds: 4 + 6 + 1 = 11 → write 1, carry 1
- Thousands: 2 + 3 + 1 = 6

(b) Difference: $1,175

Working:
```
  3,650
- 2,475
-------
  1,175
```
- Ones: 0 < 5 → borrow → 10 − 5 = 5
- Tens: 4 (after borrow) < 7 → borrow → 14 − 7 = 7
- Hundreds: 5 (after borrow) − 4 = 1
- Thousands: 3 (after borrow) − 2 = 1
Marking: 2 marks for (a) (1 for working, 1 for answer), 1 mark for (b).

19. HDB town populations. (3 marks)

Town	Population
Tampines	9,250
Jurong	9,520
Bedok	9,025
Clementi	9,502

(a) Descending order: Jurong (9,520), Clementi (9,502), Tampines (9,250), Bedok (9,025)

Working: Compare hundreds: 5 > 2 > 0. For Jurong and Clementi (both 5 hundreds), compare tens: 2 > 0 → Jurong > Clementi.

(b) Town that rounds to 9,300: Tampines (9,250)

Working: Round each to nearest hundred:
- Tampines 9,250 → tens digit is 5 → round up → 9,300 ✓
- Jurong 9,520 → 9,500
- Bedok 9,025 → 9,000
- Clementi 9,502 → 9,500
Marking: 2 marks for (a), 1 mark for (b).

20. Find the 4-digit number from clues. (2 marks)

Answer: 7,043
Working:
- Thousands digit = 7
- Hundreds digit = 0
- Tens digit = 4 more than hundreds = 0 + 4 = 4
- Ones digit = 3
- Number: 7,043
Marking: 1 mark for correct working, 1 mark for correct answer.
Common mistake: Writing 7,403 — mixing up tens and hundreds places.
