Answer Key: Version 5 of 5
Topic: Whole Numbers
Total Marks: 50
Section A: Multiple Choice Questions [10 marks]
Question 1 [1 mark]
Answer: D) 7 000
Explanation: The digit 7 is in the thousands place. In a 4-digit number, each place has a specific value:
- Thousands place: digit × 1 000
- Hundreds place: digit × 100
- Tens place: digit × 10
- Ones place: digit × 1
So 7 in the thousands place means 7 × 1 000 = 7 000.
Common mistake: Choosing A (7) — this confuses the digit itself with its place value.
Question 2 [1 mark]
Answer: A) 6 842
Explanation: To compare 4-digit numbers, always start from the left (thousands place):
- All numbers have 6 in the thousands place, so look at hundreds place
- 6 842 and 6 824 have 8 in hundreds place; 6 482 and 6 428 have 4
- Between 6 842 and 6 824: compare tens place → 4 > 2
Therefore 6 842 is the largest.
Method: Compare place values from left to right until you find a difference.
Question 3 [1 mark]
Answer: B) 5 700
Explanation: Rounding to the nearest hundred:
- Identify the hundreds digit: 5 6 78 → 6 is in hundreds place
- Look at the digit to the right (tens digit): 7
- If this digit is 5 or more, round UP the hundreds digit; if less than 5, round DOWN
- Since 7 ≥ 5, round 6 up to 7
- Replace digits to the right with zeros: 5 700
Question 4 [1 mark]
Answer: A) Four thousand and ninety
Explanation: 4 090 is broken down as:
- 4 000 → four thousand
- 0 hundreds → we say nothing for hundreds (or "and")
- 9 tens → ninety
- 0 ones → we don't say anything
We say "and" before the tens when there are no hundreds, so it's "four thousand and ninety."
Common mistake: "Four thousand nine hundred" would be 4 900.
Question 5 [1 mark]
Answer: B) 2 450
Explanation: Find the pattern: 2 150 → 2 250 → 2 350
- Difference: 2 250 − 2 150 = 100
- Difference: 2 350 − 2 250 = 100
The pattern increases by 100 each time.
- 2 350 + 100 = 2 450 ✓
- 2 450 + 100 = 2 550 ✓
Question 6 [1 mark]
Answer: D) 6 789
Explanation: Find where digit 6 appears and determine its value:
- A) 1 623: 6 is in hundreds place → value = 600
- B) 3 561: 6 is in tens place → value = 60
- C) 5 236: 6 is in ones place → value = 6
- D) 6 789: 6 is in thousands place → value = 6 000
The value of 6 is greatest in 6 789.
Question 7 [1 mark]
Answer: A) 8 053
Explanation: Build the number from its parts:
- 8 thousands = 8 000
- 5 tens = 50
- 3 ones = 3
Notice there are 0 hundreds. So we need a 0 in the hundreds place.
8 000 + 0 + 50 + 3 = 8 053
Question 8 [1 mark]
Answer: C) 6 567
Explanation: "2 000 more than" means we add 2 000.
4 567 + 2 000 = 6 567
Adding 2 000 only changes the thousands digit: 4 → 6.
Question 9 [1 mark]
Answer: A) 1 356
Explanation: For smallest 4-digit number: arrange digits in ascending order → 1, 3, 5, 6 → gives 1 356
For even number: the last digit must be even (2, 4, 6, 8, 0).
From digits 1, 3, 5, 6: only 6 is even, so it must be in the ones place.
Smallest number with 6 in ones place: put remaining digits (1, 3, 5) in ascending order in thousands, hundreds, tens places.
Result: 1 356 (even ✓, and smallest possible)
Question 10 [1 mark]
Answer: D) 4 923
Explanation: To find the missing number: _______ − 1 245 = 3 678
This is the same as: _______ = 3 678 + 1 245
Working:
3 678
+ 1 245
-------
4 923
Step by step:
- Ones: 8 + 5 = 13, write 3, carry 1
- Tens: 7 + 4 + 1 = 12, write 2, carry 1
- Hundreds: 6 + 2 + 1 = 9
- Thousands: 3 + 1 = 4
Answer: 4 923
Section B: Short Answer Questions [25 marks]
Question 11 [1 mark]
Answer: Nine thousand and forty-eight
Explanation: Break down 9 048:
- 9 000 = nine thousand
- 0 hundreds → zero hundreds (silent in words, use "and")
- 4 tens = forty
- 8 ones = eight
In Singapore convention: "Nine thousand and forty-eight"
Question 12 [2 marks]
(a) [1 mark] Answer: 7
The hundreds place is the third digit from the right: 6 7 28.
(b) [1 mark] Answer: 20 (or 2 tens)
The digit 2 is in the tens place. Its value is 2 × 10 = 20.
Common mistake: Saying "2" instead of "20". Always multiply the digit by its place value.
Question 13 [2 marks]
Answer: 3 654, 3 564, 3 465, 3 456
Explanation: All have 3 thousands, so compare hundreds:
- 3 654 has 6 hundreds (greatest)
- 3 564 has 5 hundreds
- 3 465 and 3 456 both have 4 hundreds, so compare tens: 6 > 5
Descending means from largest to smallest.
Marking: 2 marks for fully correct order; 1 mark if one number is out of place.
Question 14 [2 marks]
(a) [1 mark] Answer: 500
Working: 4 537 − 4 000 − 30 − 7 = 500
Or: 4 537 = 4 000 + 500 + 30 + 7
(b) [1 mark] Answer: 80
Working: 2 589 − 2 000 − 500 − 9 = 80
Or: 2 589 = 2 000 + 500 + 80 + 9
Question 15 [2 marks]
Answer: 7 023
Working:
2 345
+ 4 678
-------
7 023
Step by step:
- Ones: 5 + 8 = 13, write 3, carry 1
- Tens: 4 + 7 + 1 = 12, write 2, carry 1
- Hundreds: 3 + 6 + 1 = 10, write 0, carry 1
- Thousands: 2 + 4 + 1 = 7
Marking: 1 mark for correct working, 1 mark for final answer.
Question 16 [2 marks]
Answer: 3 033
Working:
5 0 0 0
- 1 9 6 7
---------
3 0 3 3
Step by step with regrouping:
- Ones: 0 − 7, need to regroup. 10 − 7 = 3
- Tens: 9 (after regrouping) − 6 = 3
- Hundreds: 9 (after regrouping) − 9 = 0
- Thousands: 4 (after regrouping) − 1 = 3
Or using standard algorithm with multiple regrouping steps shown.
Question 17 [2 marks]
Answer: 3 834 pupils
Working:
2 456
+ 1 378
-------
3 834
- Ones: 6 + 8 = 14, write 4, carry 1
- Tens: 5 + 7 + 1 = 13, write 3, carry 1
- Hundreds: 4 + 3 + 1 = 8
- Thousands: 2 + 1 = 3
"Altogether" means addition.
Question 18 [2 marks]
Answer: 1 755 stickers
Working:
3 0 0 0
- 1 2 4 5
---------
1 7 5 5
- Ones: 0 − 5, regroup: 10 − 5 = 5
- Tens: 9 − 4 = 5
- Hundreds: 9 − 2 = 7
- Thousands: 2 − 1 = 1
"Left" means subtract what was given away from what she started with.
Question 19 [2 marks]
Answer: 2 500 and 3 100
Explanation: Pattern: increases by 200 each time
- 2 100 + 200 = 2 300 ✓
- 2 300 + 200 = 2 500
- 2 500 + 200 = 2 700 ✓
- 2 700 + 200 = 2 900 ✓
- 2 900 + 200 = 3 100
Question 20 [2 marks]
(a) [1 mark] Answer: 4 962
Working: 8 962 − 4 000 = 4 962
"4 000 less than" means subtract 4 000.
(b) [1 mark] Answer: 7 930
Working: 5 430 + 2 500 = 7 930
"2 500 more than" means add 2 500.
Question 21 [2 marks]
(a) [1 mark] Answer: 7 440
Rounding to nearest ten: look at ones digit (8). Since 8 ≥ 5, round up: 7 438 → 7 440
(b) [1 mark] Answer: 7 400
Rounding to nearest hundred: look at tens digit (3). Since 3 < 5, round down: 7 4 38 → 7 400
Common mistake: Rounding to nearest hundred gives 7 400, not 7 440. Always check which place you're rounding to.
Question 22 [3 marks]
(a) [1 mark] Answer: 9 752
Greatest number: arrange digits in descending order: 9, 7, 5, 2 → 9 752
(b) [2 marks] Answer: 2 579
For smallest odd number:
- Must use all digits 2, 5, 7, 9
- Must be odd: ones digit must be odd (5, 7, or 9)
- For smallest: want smallest digits in higher places
Try: put 2 in thousands place (smallest available) Remaining: 5, 7, 9 for hundreds, tens, ones
For odd: ones can be 5, 7, or 9.
To make smallest overall: arrange remaining in ascending order as much as possible, but ensure last digit is odd.
Option 1: 2 579 (odd ✓, uses 5,7,9 in ascending order after 2) Option 2: 2 597 (odd ✓, but 597 > 579, so larger) Option 3: 2 759 (odd ✓, but larger still)
Smallest is 2 579
Marking: 1 mark for understanding "odd" constraint; 1 mark for correct arrangement. Deduct 1 if answer is even or unnecessarily large.
Question 23 [2 marks]

Or in one calculation: 4 560 + 1 235 − 987 = 4 808
Step 1: 4 560
+ 1 235
-------
5 795
Step 2: 5 795
- 987
-------
4 808
Marking: 1 mark for adding new books; 1 mark for subtracting borrowed books; 1 mark for correct final answer. Follow-through marks apply if first step is correct but arithmetic error in second.
Question 25 [3 marks]
Answer: 2 700 marbles
Working: Peter's marbles: 2 340 + 1 250 = 3 590 Mary's marbles: 3 590 − 890 = 2 700
Step 1: 2 340
+ 1 250
-------
3 590
Step 2: 3 590
- 890
-------
2 700
"More than" → add; "fewer than" → subtract
Marking: 1 mark for Peter's marbles; 1 mark for Mary's marbles; 1 mark for correct final answer with clear working.
Section C: Problem Solving [15 marks]
Question 26 [3 marks]
Answer: 210 more Primary 4 pupils
Working: Primary 4 pupils: 5 680 − 2 945 = 2 735 Difference: 2 735 − 2 945 = wait, this gives negative...
Let me recalculate: 5 680 − 2 945 = 2 735
Check: 2 735 + 2 945 = 5 680 ✓
But 2 735 < 2 945, so there are FEWER Primary 4 pupils, not more.
Number of Primary 4 pupils = 5 680 − 2 945 = 2 735 Difference: 2 945 − 2 735 = 210
There are 210 fewer Primary 4 pupils than Primary 3 pupils.
Or if question asks "how many more Primary 4 than Primary 3": answer is −210 or state "210 fewer."
Marking scheme:
- 1 mark for finding Primary 4 pupils (2 735)
- 1 mark for correct subtraction/comparison
- 1 mark for correct interpretation of "more/fewer"
Note: The question contains a subtle twist — students must recognize that Primary 4 has fewer pupils, not more. Full marks for stating "210 fewer" or equivalent.
