TuitionGoWhere Practice Paper (AI) — Version 4
Subject: Mathematics
Level: Primary 2
Paper: Practice Paper – Numbers (Whole Numbers up to 1000)
Total Marks: 40
Section A: Multiple-Choice Questions (10 marks)
1. Answer: (3) 800
The digit 8 is in the hundreds place. Its value is 8 × 100 = 800.
Common mistake: Confusing "digit" (the symbol 8) with "value" (800).
2. Answer: (1) 467
Compare hundreds first: all have 4 hundreds. Then compare tens: 6 tens (467), 7 tens (476), 4 tens (647? No, 647 has 6 hundreds). Wait — 647 and 674 have 6 hundreds, so they are bigger than 467 and 476. Between 467 and 476, 467 has 6 tens while 476 has 7 tens. So 467 is the smallest.
3. Answer: (2) 380
The pattern increases by 20 each time: 320 → 340 (+20) → 360 (+20) → 380 (+20) → 400.
Check: 380 + 20 = 400 ✓
4. Answer: (2) 348
Even numbers end in 0, 2, 4, 6, or 8. 348 ends in 8, so it is even.
235 ends in 5 (odd), 457 ends in 7 (odd), 569 ends in 9 (odd).
5. Answer: (1) 639
6 hundreds = 600, 3 tens = 30, 9 ones = 9. 600 + 30 + 9 = 639.
Section B: Short-Answer Questions (16 marks)
6. Answer: Seven hundred and fifty-four
Write the hundreds, then "hundred and", then the tens and ones together.
Marking: 1 mark for "seven hundred", 1 mark for "fifty-four" correctly spelled.
7. Answer: 500
The digit 5 is in the hundreds place. Value = 5 × 100 = 500.
Do not write "5 hundreds" — the question asks for the value.
8. Answer: 821, 812, 182, 128
Compare hundreds: 821 and 812 have 8 hundreds; 182 and 128 have 1 hundred.
Among 821 and 812: 821 has 2 tens, 812 has 1 ten → 821 > 812.
Among 182 and 128: 182 has 8 tens, 128 has 2 tens → 182 > 128.
Order: 821, 812, 182, 128.
9. Answer: 350, 300
The pattern decreases by 50 each time: 500 → 450 (−50) → 400 (−50) → 350 (−50) → 300 (−50) → 250.
Check: 300 − 50 = 250 ✓
10. Answer: >
Compare hundreds: both 6. Compare tens: 4 tens (643) vs 3 tens (634). 4 > 3, so 643 > 634.
11. Answer: 47 tens
470 = 4 hundreds 7 tens = 40 tens + 7 tens = 47 tens.
Alternatively: 470 ÷ 10 = 47.
12. Answer: 489
389 + 100 = 489.
Mental strategy: Add 1 to the hundreds digit (3 → 4), keep tens and ones the same.
13. Answer: 463
- Hundreds digit = 4
- Tens digit = 4 + 2 = 6
- Ones digit = 6 − 3 = 3
Number = 463.
Check: 6 is 2 more than 4 ✓; 3 is 3 less than 6 ✓
Section C: Structured / Long-Answer Questions (14 marks)
14.
Digits available: 2, 5, 7, 9 (use each once to form a 3-digit number; one digit will be unused).
(a) Greatest 3-digit odd number: 975
- To make the greatest number, put the largest digit in the hundreds place → 9.
- Next largest in tens place → 7.
- For an odd number, the ones digit must be odd. Remaining odd digits: 5. (2 is even, 9 and 7 used).
- So ones digit = 5.
Number: 975.
Unused digit: 2.
(b) Smallest 3-digit even number: 257? Wait — 257 is odd. Let's re-check.
- Smallest hundreds digit → 2.
- Next smallest tens digit → 5.
- For even number, ones digit must be even. Remaining digits: 7, 9 (both odd!).
- Problem: No even digit left for ones place if we use 2 in hundreds.
- So we cannot put 2 in hundreds if we need an even number.
- Try next smallest hundreds digit: 5. Then tens: 2. Ones must be even → but remaining are 7, 9 (odd).
- Try hundreds: 7. Tens: 2. Ones: even? Remaining 5, 9 (odd).
- Try hundreds: 9. Tens: 2. Ones: even? Remaining 5, 7 (odd).
- Wait — none of the digits 2,5,7,9 are even except 2.
- So the ones digit must be 2 to make an even number.
- Then hundreds digit should be as small as possible from remaining {5,7,9} → 5.
- Tens digit: next smallest from {7,9} → 7.
- Number: 572.
Check: 572 is even (ends in 2), uses 5,7,2 once each. Unused: 9. Is there smaller? 527 (odd), 752 (bigger hundreds), 725 (odd), 952 (bigger), 925 (odd). Yes, 572 is smallest even.
Correct Answers:
(a) 975
(b) 572
Marking: 1 mark for (a), 2 marks for (b) — 1 for correct reasoning that ones must be 2, 1 for correct number.
15.
(a) Rule: Add 30 to the previous number. (or "Count up in 30s")
(b) Missing numbers: 210, 240
120 → 150 (+30) → 180 (+30) → 210 (+30) → 240 (+30).
Check: 240 + 30 = 270 (not shown, but pattern holds).
Marking: 1 mark for (a), 1 mark each for 210 and 240 in (b).
16.
(a) Total children = 345 + 278 = 623
345
+ 278
-----
623
- Ones: 5 + 8 = 13 → write 3, carry 1 ten
- Tens: 4 + 7 + 1 (carry) = 12 → write 2, carry 1 hundred
- Hundreds: 3 + 2 + 1 (carry) = 6
(b) More boys = 345 − 278 = 67
345
- 278
-----
67
- Ones: 5 − 8 (cannot) → borrow 1 ten → 15 − 8 = 7
- Tens: 3 (after borrow) − 7 (cannot) → borrow 1 hundred → 13 − 7 = 6
- Hundreds: 2 (after borrow) − 2 = 0
Marking: (a) 2 marks (1 for correct method/working, 1 for correct answer); (b) 2 marks (1 for method, 1 for answer).
17.
Pages read = 125 + 148 = 273
125
+ 148
-----
273
Pages left = 500 − 273 = 227
500
- 273
-----
227
- Ones: 0 − 3 (borrow from tens, but tens is 0 → borrow from hundreds)
Hundreds: 5 → 4, Tens: 0 → 10, then Tens lend to Ones → Tens: 9, Ones: 10
10 − 3 = 7 - Tens: 9 − 7 = 2
- Hundreds: 4 − 2 = 2
Answer: 227 pages
Marking: 2 marks for finding total pages read (1 method, 1 answer), 2 marks for subtraction (1 method, 1 answer).
