Answer Key and Marking Scheme

Version: 1 of 5 Subject: Mathematics Level: Primary 2 Paper: Practice Paper - Numbers

Section A: Multiple Choice (10 marks)

Question	Answer	Working/Explanation	Marks
1	C	The digit 8 is in the hundreds place, so its value is 8 × 100 = 800.	[1]
2	C	Compare hundreds digits first: 279 and 297 both have 2 hundreds (smaller than 7 hundreds). Between 279 and 297, compare tens: 7 tens < 9 tens, so 279 is smallest.	[1]
3	A	450 + 30: 4 hundreds + 5 tens + 3 tens = 4 hundreds + 8 tens = 480.	[1]
4	C	Pattern increases by 10 each time: 235, 245, 255, 265, 275. Rule: add 10.	[1]
5	C	Even numbers end in 0, 2, 4, 6, 8. 526 ends in 6, so it is even. (357→odd, 413→odd, 681→odd)	[1]
6	A	600 − 247: Use standard subtraction with regrouping. 600 − 200 = 400, then 400 − 47 = 353. Or: 600 − 247 = (600 − 300) + 53 = 353.	[1]
7	B	5 hundreds = 500, 7 ones = 7. No tens mentioned, so 0 tens. Answer: 507.	[1]
8	A	Compare hundreds: 3__ < 5__ < 8__. So 358, 385 < 583 < 835. Order: 358, 385, 583, 835.	[1]
9	D	Check each: 423 < 432 (false); 289 < 298 (false, not equal); 675 > 657 (false); 541 > 514 (true: 4 tens > 1 ten).	[1]
10	A	Hundreds: 6. Tens: 6 − 2 = 4. Ones: 5. Number: 645.	[1]

Section A Total: 10 marks

Section B: Short Answer (18 marks)

11. Write 709 in words.

Answer: Seven hundred and nine [2]

Marking:

"Seven hundred" correct: [1]
"and nine" correct: [1]
Common error: "Seven zero nine" or "Seven oh nine" → [0] for that part

Teaching note: In Singapore, we write "seven hundred and nine" using 'and' before the ones. The digit 0 in tens place means there are zero tens, so we skip saying any tens.

12. (a) What is the value of the digit 4 in 549?

Answer: 40 (or 4 tens) [1]

(b) What is the value of the digit 5 in 549?

Answer: 500 (or 5 hundreds) [1]

Teaching note: The digit 4 is in the tens place, so its value is 4 × 10 = 40. The digit 5 is in the hundreds place, so its value is 5 × 100 = 500. Remind students: "digit" = the symbol (4), "value" = what it's worth (40).

[Total: 2 marks]

13. Fill in the blanks.

(a) 300 + 40 + 7 = 347 [1]

(b) 800 + 50 + 3 = 853 [1]

(c) 400 + 60 + 9 = 469 [1]

Working:

(a) 3 hundreds + 4 tens + 7 ones = 347
(b) 853 − 800 − 3 = 50, so missing number is 50 (5 tens)
(c) 469 − 60 − 9 = 400, so missing number is 400 (4 hundreds)

Teaching note: This tests expanded form. Break numbers into hundreds + tens + ones. For (b) and (c), work backwards by subtracting what you know.

[Total: 3 marks]

14. (a) Is 438 odd or even?

Answer: even (circle "even") [1]

(b) Write the next two even numbers after 438.

Answer: 440, 442 [2]

Working: Even numbers are divisible by 2 (end in 0, 2, 4, 6, 8). 438 is even. Add 2 to get next even: 438 + 2 = 440, 440 + 2 = 442.

Marking:

Each correct number: [1]
Common error: 439, 440 → [0] as 439 is odd

Teaching note: Even numbers always differ by 2. After an even number, skip the next odd number to find the next even.

[Total: 3 marks]

15. Arrange from biggest to smallest: 628, 286, 862, 268, 826

Answer: 862, 826, 628, 286, 268 [2]

Working:

Step 1: Compare hundreds digits: 8__ > 6__ > 2__
Step 2: For 8__ numbers: 862 vs 826 → 6 tens > 2 tens, so 862 > 826
Step 3: For 2__ numbers: 286 vs 268 → 8 tens > 6 tens, so 286 > 268

Marking:

Correct order with all 5 numbers: [2]
Reversed order (smallest to biggest): [0]
One number misplaced: [1]

[Total: 2 marks]

16. Pattern: 180, 220, 260, ______, ______, 380

(a) Find the rule for the pattern.

Answer: Add 40 (or "increase by 40" or "counting in 40s") [1]

(b) Fill in the two missing numbers.

Answer: 300, 340 [2]

Working: 220 − 180 = 40; 260 − 220 = 40. Rule: add 40.

260 + 40 = 300
300 + 40 = 340
Check: 340 + 40 = 380 ✓

Marking:

Both numbers correct: [2]
One correct, pattern identified: [1]

Teaching note: To find a pattern rule, subtract consecutive terms. Always check your rule works for the whole pattern.

[Total: 3 marks]

Section C: Word Problems and Reasoning (12 marks)

17. Mrs Tan has 500 stickers. Gives away 175. Buys 240 more. Final amount?

Answer: 565 stickers [3]

Working:

Step	Working	Marks
1	Stickers left after giving away: 500 − 175 = 325	[1]
2	Stickers after buying more: 325 + 240 = 565	[1]
3	Correct final answer with units: 565 stickers	[1]

Alternative method: 500 + 240 = 740, then 740 − 175 = 565

Teaching note: This is a two-step problem. First subtract (give away = less), then add (buy more = more). The bar model shows: start bar, cut off 175, add 240 to the remainder.

Expected visual: Bar model with three parts: whole bar labelled 500, middle segment removed (175), new segment added (240), final bar labelled 565.

18. Hundreds digit = 7. Tens digit = 3 more than hundreds. Ones digit = 4 less than tens.

(a) Tens digit = 7 + 3 = 10... wait, that's two digits!

Let me re-read: "3 more than my hundreds digit" → 7 + 3 = 10. This seems wrong for a single digit.

Corrected interpretation: Re-examining: The problem as stated gives tens digit = 10, which is impossible. Assuming intended: tens digit is 4 (perhaps "3 less" was meant, or there's an error).

However, following the problem exactly: This question has no valid answer as stated (a digit cannot be 10). [1] for identifying this, or if we assume tens digit is 4 (corrected):

Assuming corrected version: tens digit is 4 (3 less than hundreds)

(a) Tens digit: 4 [1]

(b) Ones digit: 4 − 4 = 0 [1]

(c) Number: 740 [1]

Note: If examiners intended original, accept "no valid number" with explanation as correct reasoning. [3]

19. John: 358. Peter: 147 more than John. Mary: 86 fewer than Peter.

(a) Peter's marbles:

Working: 358 + 147 = 505 marbles [2]

Step	Calculation	Marks
1	358 + 147 = 358 + 100 + 40 + 7 = 505	[1]
2	Correct answer with units: 505 marbles	[1]

(b) Mary's marbles:

Working: 505 − 86 = 419 marbles [2]

Step	Calculation	Marks
1	505 − 86 = 505 − 100 + 14 = 419 (or standard subtraction with regrouping)	[1]
2	Correct answer with units: 419 marbles	[1]

Teaching note: "More than" → add. "Fewer than" → subtract. Check: Peter has more than John (505 > 358 ✓). Mary has fewer than Peter (419 < 505 ✓).

20. Number machine: IN → ×2 then +10 → OUT

Image pending generation: diagram for Q20.

(a) IN = 5:

Working: 5 × 2 = 10, then 10 + 10 = 20

Answer: 20 [1]

(b) IN = 20:

Working: 20 × 2 = 40, then 40 + 10 = 50

Answer: 50 [1]

(c) Is Tom correct? IN = 100, claims OUT = 220.

Working:

Correct calculation: 100 × 2 = 200, then 200 + 10 = 210
Tom's answer: 220

Answer: No, Tom is not correct. [1] for "No" with working showing 210

Step	Marks
Correct method: 100 × 2 = 200, 200 + 10 = 210	[1]
States "No" and gives correct answer 210 (not 220)	[1]

Teaching note: Two-step machines must be done in order. Common error: ×2 and +10 done in wrong order, or adding first: 100 + 10 = 110, ×2 = 220 (Tom's mistake!). This shows why order of operations matters.
