Version:	3 of 5
Total Marks:	50 marks

SECTION A: Multiple Choice (10 marks)

Working marks are not awarded in MCQ; answers are either correct or incorrect.

1. In the number 7,539, which digit is in the hundreds place?

Answer: (2) 5

Explanation:

Place value positions from right to left: ones, tens, hundreds, thousands
7,539 = 7 thousands + 5 hundreds + 3 tens + 9 ones
The hundreds place is the third digit from the right: 5
Common mistake: Choosing 3 (the digit '3' is in the tens place, not hundreds)

Mark: 1 mark

2. What is the value of the digit 4 in 4,862?

Answer: (4) 4,000

Explanation:

The digit 4 is in the thousands place
Value of digit = digit × place value = 4 × 1,000 = 4,000
Key concept: "Value of digit" means how much that digit represents, not just the digit itself
Common mistake: Choosing 4 (this is the digit itself, not its value)

Mark: 1 mark

3. Which number is the smallest?

Answer: (2) 3,052

Explanation:

Compare digit by digit from left to right:
- All have 3 in thousands place → compare hundreds
- 3,205 has 2 hundreds
- 3,052 has 0 hundreds ← smallest
- 3,502 has 5 hundreds
- 3,250 has 2 hundreds
Since 0 < 2 < 5, the number with 0 hundreds is smallest: 3,052

Mark: 1 mark

4. 5 thousands, 8 hundreds, 2 tens, and 7 ones = ____

Answer: (2) 5,827

Explanation:

5 thousands = 5,000
8 hundreds = 800
2 tens = 20
7 ones = 7
Total: 5,000 + 800 + 20 + 7 = 5,827

Mark: 1 mark

5. What is 6,209 rounded to the nearest hundred?

Answer: (2) 6,200

Explanation:

For rounding to nearest hundred, look at the tens digit (0)
If tens digit is 0, 1, 2, 3, or 4 → round down
If tens digit is 5, 6, 7, 8, or 9 → round up
Tens digit is 0, so round down: 6,209 → 6,200

Mark: 1 mark

6. Which of the following is an even number?

Answer: (2) 4,562

Explanation:

Even numbers end in 0, 2, 4, 6, or 8
Odd numbers end in 1, 3, 5, 7, or 9
Check the ones digit: 4,562 ends in 2, so it is even
4,561 (ends in 1), 4,563 (ends in 3), 4,565 (ends in 5) are all odd

Mark: 1 mark

7. What is the next number in the pattern: 2,450, 2,460, 2,470, 2,480, ____?

Answer: (2) 2,490

Explanation:

Find the difference between consecutive terms:
- 2,460 − 2,450 = 10
- 2,470 − 2,460 = 10
- 2,480 − 2,470 = 10
The pattern increases by 10 each time
Next number: 2,480 + 10 = 2,490

Mark: 1 mark

8. The number 9,006 in words is:

Answer: (1) Nine thousand and six

Explanation:

9,006 = 9,000 + 6 = nine thousand + six
Standard form: "Nine thousand and six" (Singapore convention)
Common mistake: "Ninety thousand and six" would be 90,006 (wrong place value)

Mark: 1 mark

9. Which number is 1,000 more than 6,789?

Answer: (2) 7,789

Explanation:

"1,000 more than" means add 1,000
6,789 + 1,000 = 7,789
Alternatively: add 1 to the thousands digit: 6 → 7, keeping other digits the same

Mark: 1 mark

10. In a 4-digit number, the digit in the thousands place is 8. The digit in the ones place is twice the digit in the thousands place. What is the digit in the ones place?

Answer: (3) 16

Explanation:

Wait — re-read carefully. A digit must be 0-9.
Thousands place digit = 8
Ones place digit = 2 × 8 = 16
But 16 is not a single digit!
However, looking at options: (1) 4 would be half, (2) 8 would be same, (3) 16 is twice, (4) 2 is not related.
The question asks what the digit in the ones place would be based on the description, even though 16 is not a valid digit. This tests careful reading.

Revised interpretation: The question contains a trick — 16 is not a valid digit. If this were a real exam, there might be no correct answer. However, following the mathematical operation: 2 × 8 = 16.

Mark: 1 mark (tests understanding that digit values can be calculated even if result is invalid)

Note for teacher: This question tests critical thinking. The "correct" mathematical answer is 16, but students should recognize this creates an impossible number. In practice, no valid 4-digit number satisfies this condition.

SECTION B: Short Answer (25 marks)

11. Write 5,080 in words.

Answer: Five thousand and eighty

Marking scheme:

"Five thousand" — 1 mark
"and eighty" — 1 mark
Common mistake: "Five thousand eighty" (missing "and") or "Five thousand and eight" (missing tens)

Explanation:

5,080 = 5,000 + 80
The zero in hundreds place is not read out
The zero in ones place is not read out
"and" connects the thousands to the remaining amount

Mark: 2 marks

12. Arrange these numbers from smallest to largest: 4,127, 4,721, 4,172, 4,217

Answer: 4,127, 4,172, 4,217, 4,721

Marking scheme:

Correct order — 2 marks
Any error in ordering — 0 marks

Step-by-step method:

All have 4 in thousands place → compare hundreds:
- 4,127 and 4,172 have 1 hundred
- 4,217 has 2 hundreds
- 4,721 has 7 hundreds
Compare 4,127 vs 4,172 (both have 1 hundred): compare tens
- 4,127 has 2 tens
- 4,172 has 7 tens
- So 4,127 < 4,172
Final order: 4,127 < 4,172 < 4,217 < 4,721

Mark: 2 marks

13. What is the value of the digit 7 in 7,084?

Answer: 7,000; seven thousand

Marking scheme:

"7,000" or "7000" — 1 mark
"Seven thousand" — 1 mark

Explanation:

The digit 7 is in the thousands place
Value = 7 × 1,000 = 7,000
In words: seven thousand

Common mistakes:

Writing "7" (this is the digit, not its value)
Writing "700" (wrong place value — would be hundreds place)

Mark: 2 marks

14. Form the greatest 4-digit number using the digits 5, 2, 8, and 3. Each digit can only be used once.

Answer: 8,532

Marking scheme:

Correct answer — 2 marks
Any other arrangement — 0 marks

Step-by-step method:

To make the greatest number, place the largest digit in the highest place value position
Digits in order: 8 > 5 > 3 > 2
Arrange from left to right: thousands → hundreds → tens → ones
Greatest number: 8,532

Verification: 8,532 > 8,523 > 8,352 > ... > all other arrangements

Mark: 2 marks

15(a) Round 4,567 to the nearest ten.

15(b) Round 4,567 to the nearest hundred.

Answer: 4,600

Marking scheme: 1 mark

Explanation:

Look at the tens digit: 6

4,567 → 4,600

Mark: 1 mark

16. Complete the number pattern: 3,100, 3,300, 3,500, _______, 3,900

Answer: 3,700

Marking scheme:

Correct answer — 2 marks
Any error — 0 marks

Step-by-step method:

Find the difference: 3,300 − 3,100 = 200
3,500 − 3,300 = 200
Pattern: add 200 each time
Missing number: 3,500 + 200 = 3,700
Check: 3,700 + 200 = 3,900 ✓

Mark: 2 marks

17. A school has 2,456 pupils. Another school has 1,289 more pupils than the first school. How many pupils are there in the second school?

Answer: 3,745 pupils

Marking scheme:

Correct method shown (addition) — 1 mark
Correct final answer — 1 mark
Correct units — 1 mark

Step-by-step working:

  2,456
+ 1,289
--------
  3,745

Ones: 6 + 9 = 15 (write 5, carry 1)
Tens: 5 + 8 + 1 = 14 (write 4, carry 1)
Hundreds: 4 + 2 + 1 = 7 (write 7)
Thousands: 2 + 1 = 3 (write 3)

Answer: 3,745 pupils

"More than" means we need to add.

Mark: 3 marks

18. Mei Ling collected 3,428 stamps. She gave away 1,567 stamps to her brother. How many stamps does she have left?

Answer: 1,861 stamps

Marking scheme:

Correct method shown (subtraction) — 1 mark
Correct final answer — 1 mark
Correct units — 1 mark

Step-by-step working:

  3,428
- 1,567
--------
  1,861

Ones: 8 − 7 = 1
Tens: 2 − 6 (can't do, borrow from hundreds)
- 12 − 6 = 6
Hundreds: 3 − 5 (can't do, borrowed already so 2 − 5, need to borrow from thousands)
- Actually: 4 became 3, then 3 became 13 after borrowing, 13 − 5 = 8? Let me recalculate.

Correct working with proper borrowing:

  3,428
- 1,567
--------

Ones: 8 − 7 = 1
Tens: 2 < 6, borrow from hundreds. 4 becomes 3, 2 becomes 12. 12 − 6 = 6
Hundreds: 3 < 5? No, 3 = 3, but we need 3 − 5. Borrow from thousands. 3 becomes 13, wait: 3 (after first borrow) − need to borrow again.

Let me re-express:

Thousands: 3, hundreds: 4, tens: 2, ones: 8

Borrowing process:

Ones: 8 − 7 = 1 ✓
Tens: need 2 − 6, borrow from 4. So 4 → 3, 2 → 12. 12 − 6 = 6 ✓
Hundreds: now 3 − 5, need to borrow from 3 (thousands). 3 → 2, 3 → 13. 13 − 5 = 8? Wait, let me check: 3,428 − 1,567.

Verification: 1,861 + 1,567 = 3,428?

1,861 + 1,567 = 3,428 ✓

So working is:

Thousands: 3 → 2 (after borrowing)
Hundreds: 13 − 5 = 8? But 2, 8, 6, 1 would be 2,861. That's wrong.

Let me recalculate more carefully:

    3 4 2 8
  - 1 5 6 7
  ---------

Step 1: 8 − 7 = 1

Step 2: 2 − 6, need borrow. Look at hundreds (4).

4 becomes 3, 2 becomes 12
12 − 6 = 6

Step 3: Now hundreds is 3, need 3 − 5. Need borrow from thousands (3).

3 becomes 2, 3 becomes 13
13 − 5 = 8

Step 4: Thousands: 2 − 1 = 1

Result: 1,861

Wait, that gives 1,861. Let me verify: 1,861 + 1,567 = 3,428?

1,861 + 1,567: 1+7=8, 6+6=12, 8+5+1=14, 1+1+1=3 = 3,428 ✓

So answer is 1,861 stamps.

Mark: 3 marks

19. A bookshelf can hold 2,400 books. There are 1,856 books on the shelf already. How many more books can be placed on the shelf?

Answer: 544 books

Marking scheme:

Correct method shown (subtraction) — 1 mark
Correct final answer — 1 mark
Correct units — 1 mark

Step-by-step working:

  2,400
- 1,856
--------
    544

Ones: 0 − 6, borrow. 0 → 10, 10 − 6 = 4
Tens: 0 → 9 (after borrow), 9 − 5 = 4
Hundreds: 4 → 3 (after borrow), 3 − 8, need borrow from thousands. 3 → 13, 13 − 8 = 5
Thousands: 2 → 1 (after borrow), 1 − 1 = 0

Verification: 1,856 + 544 = 2,400?

1,856 + 544 = 2,400 ✓

Answer: 544 books

Mark: 3 marks

20. The sum of two numbers is 8,000. One of the numbers is 3,456. What is the other number?

Answer: 4,544

Marking scheme:

Correct method shown (subtraction from sum) — 1 mark
Correct final answer — 1 mark
Correct working clarity — 1 mark

Step-by-step working:

Sum = 8,000, one number = 3,456, other number = ?
Other number = 8,000 − 3,456 = 4,544

  8,000
- 3,456
--------
  4,544

Ones: 0 − 6, borrow chain. 0 → 10, 10 − 6 = 4
Tens: 0 → 9, 9 − 5 = 4
Hundreds: 0 → 9 (after borrow chain), 9 − 4 = 5? Wait, let me recalculate.

Correct borrowing:

  8 0 0 0
- 3 4 5 6
--------

Ones: 0−6, borrow from tens. Tens is 0, so need to borrow from hundreds. Hundreds is 0, need to borrow from thousands.
Thousands: 8 → 7
Hundreds: 0 → 10, then immediately lend to tens: 10 → 9
Tens: 0 → 10, then lend to ones: 10 → 9, ones: 0 → 10
Ones: 10 − 6 = 4
Tens: 9 − 5 = 4
Hundreds: 9 − 4 = 5
Thousands: 7 − 3 = 4

Result: 4,544

Verification: 3,456 + 4,544 = 8,000? Yes ✓

Mark: 3 marks

SECTION C: Problem Solving (15 marks)

21. Mr Tan has 5,000 Singapore stamps and 2,875 foreign stamps. He wants to pack all his stamps into boxes. Each box can hold 100 stamps.

21(a) How many stamps does Mr Tan have altogether? [2]

Answer(a): 7,875 stamps

Marking scheme:

Correct addition method — 1 mark
Correct answer with units — 1 mark

Step-by-step working:

  5,000
+ 2,875
--------
  7,875

Total stamps = 5,000 + 2,875 = 7,875 stamps

21(b) How many boxes does he need to pack all his stamps? [2]

Answer(b): 79 boxes

Marking scheme:

Recognize need to divide by 100 or use grouping — 1 mark
Correct answer with reasoning about remainder — 1 mark

Step-by-step working:

7,875 ÷ 100 = 78 remainder 75
Or: 7,875 = 78 × 100 + 75
78 full boxes + 1 extra box for remaining 75 stamps = 79 boxes

Critical reasoning: Even though 75 < 100, we still need one more box for the remaining stamps. We cannot leave stamps unpacked.

Alternative method:

7,900 would need 79 boxes exactly
7,875 is 25 less than 7,900, but still needs the same 79 boxes (the last box is just not full)

Mark: 2 marks for part (b)

22. Three schools collected cans for recycling.

<image_placeholder> id: Q22-fig1 type: table linked_question: Q22 description: A table showing the number of cans collected by three schools labels: School A, School B, School C, Number of cans values: School A: 3,456 cans, School B: 2,098 cans, School C: 2,987 cans must_show: Three rows with school names and their corresponding number of cans in a clear tabular format with proper alignment </image_placeholder>

Expected visual: A table with two columns (School, Number of cans) and three data rows.

22(a) How many more cans did School A collect than School B? [2]

Answer(a): 1,358 cans

Marking scheme:

Correct subtraction method — 1 mark
Correct answer with units — 1 mark

Step-by-step working:

  3,456
- 2,098
--------
  1,358

School A: 3,456 cans
School B: 2,098 cans
Difference: 3,456 − 2,098 = 1,358 cans

Verification: 2,098 + 1,358 = 3,456?

2,098 + 1,358 = 3,456 ✓

22(b) What is the total number of cans collected by all three schools? [2]

Answer(b): 8,541 cans

Marking scheme:

Correct addition of all three numbers — 1 mark
Correct answer with units — 1 mark

Step-by-step working:

  3,456
+ 2,098
--------
  5,554

  5,554

--------
  8,541

Or in one step:

  3,456
  2,098
+ 2,987
--------
  8,541

Total = 3,456 + 2,098 + 2,987 = 8,541 cans

Verification: 3,456 + 2,098 = 5,554; 5,554 + 2,987 = 8,541 ✓

Mark: 2 marks for part (b)

23. A number, when rounded to the nearest hundred, becomes 7,200.

23(a) What is the greatest possible value of this number? [2]

Answer(a): 7,249

Marking scheme:

Understanding the rounding boundary — 1 mark
Greatest value in range — 1 mark

Concept explanation:

Numbers rounding to 7,200 (nearest hundred) are in the range 7,150 to 7,249
The boundary rule:
- 7,150 rounds up to 7,200 (tens digit is 5, round up)
- 7,149 rounds down to 7,100
- 7,249 rounds down to 7,200 (tens digit is 4, round down)
- 7,250 rounds up to 7,300

Greatest possible value: 7,249

23(b) What is the smallest possible value of this number? [2]

Answer(b): 7,150

Marking scheme:

Understanding the lower boundary — 1 mark
Smallest value in range — 1 mark

Explanation:

The smallest number that rounds up to 7,200 is 7,150
7,149 would round down to 7,100
7,150 has tens digit 5, so rounds up to 7,200

Smallest possible value: 7,150

23(c) Is 7,249 one of the possible numbers? Explain your answer. [1]

Answer(c): Yes, 7,249 is one of the possible numbers because when rounded to the nearest hundred, it becomes 7,200. The tens digit is 4, which is less than 5, so we round down.

Marking scheme:

Correct answer (Yes) — 0.5 marks
Correct explanation with reference to tens digit — 0.5 marks

Explanation:

7,249: the tens digit is 4
Since 4 < 5, we round down to 7,200
Therefore 7,249 is a possible number

Common mistake: Saying "No" because 7,249 is greater than 7,200. The question asks if it rounds to 7,200, not if it equals 7,200.

<image_placeholder> id: Q24-fig1 type: diagram linked_question: Q24 description: A diagram showing boxes arranged in a pattern with numbers labels: Box 1, Box 2, Box 3, Box 4, Box 5, with numbers 2,450, 2,550, 2,650, 2,750, ? values: First number: 2,450, Second number: 2,550, Third number: 2,650, Fourth number: 2,750 must_show: Five boxes in a row, first four filled with the given numbers, fifth box empty with a question mark, arrows or visual indication of the pattern progression </image_placeholder>

Expected visual: Five boxes in horizontal sequence with numbers and visual arrows showing +100 between each.

24(a) What is the number in Box 5? [2]

Answer(a): 2,850

Marking scheme:

Correct pattern identification — 1 mark
Correct calculation for Box 5 — 1 mark

Step-by-step working:

Box 1: 2,450
Box 2: 2,550 = 2,450 + 100
Box 3: 2,650 = 2,550 + 100
Box 4: 2,750 = 2,650 + 100
Pattern: add 100 each time

Box 5: 2,750 + 100 = 2,850

24(b) What is the number in Box 10? [2]

Answer(b): 3,350

Marking scheme:

Correct method (pattern extension or formula) — 1 mark
Correct answer — 1 mark

Step-by-step working:

Method 1: Continue the pattern

Box 5: 2,850
Box 6: 2,950
Box 7: 3,050
Box 8: 3,150
Box 9: 3,250
Box 10: 3,350

Method 2: Use formula (faster and more reliable)

From Box 1 to Box 10, we add the pattern 9 times
Number in Box n = 2,450 + (n − 1) × 100
Box 10 = 2,450 + 9 × 100 = 2,450 + 900 = 3,350

Verification with Method 1: 3,350 ✓
