TuitionGoWhere Practice Paper - Mathematics Primary 1 (Answer Key)

Subject: Mathematics
Level: Primary 1
Paper: Practice Paper 2 (Numbers up to 100)
Total Marks: 30

Section A: Multiple-Choice Questions (10 marks)

1. Answer: 3 (14)
Marks: 1
Explanation: Count each star one by one. There are 14 stars in total.
Common mistake: Miscounting by skipping or double-counting a star. Encourage students to point and count aloud.

2. Answer: 3 (60)
Marks: 1
Explanation: In the number 63, the digit 6 is in the tens place. Its value is 6 tens = 60. The digit 3 is in the ones place (value = 3).
Key concept: Place value — the position of a digit determines its value.

3. Answer: 3 (45)
Marks: 1
Explanation: Compare the tens digit first. 45 has 4 tens; 48 has 4 tens; 54 has 5 tens; 84 has 8 tens. Among those with 4 tens (45 and 48), compare the ones: 5 < 8, so 45 is the smallest.

4. Answer: 3 (40)
Marks: 1
Explanation: The pattern increases by 5 each time: 25 (+5) → 30 (+5) → 35 (+5) → 40 (+5) → 45.

5. Answer: 3 (43)
Marks: 1
Explanation: "Altogether" means addition. 28 + 15 = 43.
Working: 28 + 10 = 38, 38 + 5 = 43. Or column addition: 8+5=13 (write 3, carry 1), 2+1+1=4 → 43.

6. Answer: 2 (49, 58, 65, 72)
Marks: 1
Explanation: Arrange from smallest to biggest by comparing tens then ones: 49 (4 tens), 58 (5 tens), 65 (6 tens), 72 (7 tens).

7. Answer: 2 (5 tens 2 ones)
Marks: 1
Explanation: 52 = 50 + 2 = 5 tens 2 ones. The first digit (5) is tens; the second digit (2) is ones.

8. Answer: 1 (29)
Marks: 1
Explanation: 46 − 17. Subtract ones: 6 − 7 cannot, so regroup 1 ten from 4 tens → 3 tens, 16 ones. 16 − 7 = 9. Subtract tens: 3 − 1 = 2. Answer = 29.
Check: 29 + 17 = 46 ✓

9. Answer: 1 (17)
Marks: 1
Explanation: Total children = 35. Girls = 18. Boys = Total − Girls = 35 − 18 = 17.
Working: 35 − 10 = 25, 25 − 8 = 17.

10. Answer: 2 (79)
Marks: 1
Explanation: The number just before 80 is one less: 80 − 1 = 79.

Section B: Short-Answer Questions (12 marks)

11.
Numerals: 17
Words: seventeen
Marks: 2 (1 mark for correct numeral, 1 mark for correct spelling in words)
Explanation: Count the circles: top row has 10, bottom row has 7. 10 + 7 = 17. Write "17" in numerals and "seventeen" in words.
Note: Accept "seventeen" only; "17" in words box is incorrect.

12.
(a) 6 tens 9 ones = 69
(b) 84 = 8 tens 4 ones
Marks: 2 (1 mark each)
Explanation:
(a) 6 tens = 60, 9 ones = 9 → 60 + 9 = 69.
(b) In 84, the digit 8 is in the tens place (8 tens = 80), the digit 4 is in the ones place (4 ones = 4).

13.
(a) 56 < 65
(b) 73 > 37
(c) 49 = 49
Marks: 3 (1 mark each)
Explanation: Compare tens first.
(a) 5 tens < 6 tens → 56 < 65.
(b) 7 tens > 3 tens → 73 > 37.
(c) Same number → equal.

14.
68, 63, 58, 53, 48, 43
Marks: 2 (1 mark per missing number)
Explanation: The pattern decreases by 5 each time. 58 − 5 = 53, 53 − 5 = 48, 48 − 5 = 43 (matches given).

15.
3 7

  • 2 5

6 2
Marks: 2 (1 mark for correct ones digit with regrouping shown or implied, 1 mark for correct final answer)
Working:
Ones: 7 + 5 = 12 → write 2, carry 1 ten.
Tens: 3 + 2 + 1 (carried) = 6.
Answer: 62.

16.
8 4

  • 2 9

5 5
Marks: 2 (1 mark for correct regrouping, 1 mark for correct final answer)
Working:
Ones: 4 − 9 cannot → regroup 1 ten from 8 tens → 7 tens, 14 ones. 14 − 9 = 5.
Tens: 7 − 2 = 5.
Answer: 55.
Check: 55 + 29 = 84 ✓

17.
Working: 42 − 15 = 27
Answer: 27 apples
Marks: 2 (1 mark for correct subtraction method/working, 1 mark for correct answer with unit)
Explanation: "Taken out" means subtract. 42 − 15: ones 2−5 regroup → 12−5=7; tens 3−1=2 → 27.

Section C: Word Problems (8 marks)

18.
Working:
Stickers given away = 14 + 8 = 22
Stickers left = 36 − 22 = 14
Answer: 14 stickers
Marks: 3
Mark breakdown:

  • 1 mark for finding total given away (14 + 8 = 22)
  • 1 mark for correct subtraction (36 − 22)
  • 1 mark for correct final answer with unit
    Explanation: Two-step problem. First add the stickers given to son and daughter (14 + 8 = 22). Then subtract from the total (36 − 22 = 14).
    Alternative method: 36 − 14 = 22, then 22 − 8 = 14.

19.
Working:
Total children at first = 27 + 25 = 52
Children left = 52 − 12 = 40
Answer: 40 children
Marks: 3
Mark breakdown:

  • 1 mark for finding total children (27 + 25 = 52)
  • 1 mark for correct subtraction (52 − 12)
  • 1 mark for correct final answer with unit
    Explanation: First find the total number of children (boys + girls = 27 + 25 = 52). Then subtract the 12 who went home (52 − 12 = 40).

20.
Working:
After putting in: 50 + 18 = 68
After taking out: 68 − 25 = 43
Answer: 43 marbles
Marks: 2
Mark breakdown:

  • 1 mark for correct first step (50 + 18 = 68)
  • 1 mark for correct final answer with unit
    Explanation: Three-step problem. Start with 50. Add 18 (puts in) → 68. Subtract 25 (takes out) → 43.
    Common mistake: Doing 50 − 25 first, then adding 18 (gives 43 by coincidence but wrong sequence). Emphasise following the story order.
