Answers

Primary 1 Mathematics Quiz - Numbers (Answer Key)

Total Marks: 30

Section A: Multiple Choice Questions (5 × 1 mark = 5 marks)

1. Answer: (3) 14
Explanation: Count each apple one by one. There are 7 apples in the first row and 7 apples in the second row. 7 + 7 = 14 apples altogether.
Marking: 1 mark for correct answer.

2. Answer: (3) 60
Explanation: In the number 63, the digit 6 is in the tens place. The value of a digit in the tens place is the digit × 10. So, 6 × 10 = 60.
Common mistake: Choosing (1) 6 confuses the digit with its value.
Marking: 1 mark for correct answer.

3. Answer: (1) 48
Explanation: Compare the tens digit first. 48 has 4 tens, 84 has 8 tens, 57 has 5 tens, 75 has 7 tens. The smallest tens digit is 4, so 48 is the smallest number.
Marking: 1 mark for correct answer.

4. Answer: (2) 18
Explanation: The pattern increases by 2 each time: 12 (+2) → 14 (+2) → 16 (+2) → 18 (+2) → 20 (+2) → 22.
Marking: 1 mark for correct answer.

5. Answer: (3) Card C
Explanation: The number that comes just before 50 is 49. Card C shows 49.
Marking: 1 mark for correct answer.

Section B: Short Answer Questions (10 × 2 marks = 20 marks)

6. Numerals: 23
Words: twenty-three
Explanation: Count the stars carefully. There are 5 groups of 4 stars (20) plus 3 more stars = 23 stars. In words, numbers 21–29 are written with a hyphen: twenty-three.
Marking: 1 mark for correct numerals, 1 mark for correct words (spelling must be correct).

7. (a) 54 = 5 tens 4 ones
(b) 8 tens 2 ones = 82
Explanation:
(a) The number 54 has 5 in the tens place (5 tens = 50) and 4 in the ones place (4 ones = 4).
(b) 8 tens = 80, 2 ones = 2. 80 + 2 = 82.
Marking: 1 mark each part.

8. 36, 39, 63, 93
Explanation: Compare tens digits first: 36 and 39 have 3 tens; 63 has 6 tens; 93 has 9 tens. Among 36 and 39, compare ones: 6 < 9, so 36 comes before 39. Order: 36, 39, 63, 93.
Marking: 2 marks for fully correct order; 1 mark if only one error.

9. 25, 30, 35, 40, 45, 50
Explanation: The pattern increases by 5 each time (counting in fives). 35 + 5 = 40, 40 + 5 = 45.
Marking: 1 mark for each correct missing number (40 and 45).

10. (a) Circle 72
(b) Circle 81
Explanation:
(a) Compare 27 (2 tens), 72 (7 tens), 57 (5 tens). 7 tens is the greatest → 72.
(b) Compare 81 (8 tens), 18 (1 ten), 48 (4 tens). 8 tens is the greatest → 81.
Marking: 1 mark each part.

11. Answer: 56
Explanation: "10 more than 46" means add 10 to 46. 46 + 10 = 56. On a number chart, this is one row down from 46.
Marking: 2 marks for correct answer; 1 mark for correct method (46 + 10) but calculation error.

12. Answer: 33
Explanation: "5 less than 38" means subtract 5 from 38. 38 − 5 = 33. Count back 5 from 38: 37, 36, 35, 34, 33.
Marking: 2 marks for correct answer; 1 mark for correct method (38 − 5) but calculation error.

13. Answer: 26
Explanation: First ten-frame: 10 counters. Second ten-frame: 10 counters. Third ten-frame: 6 counters. Total = 10 + 10 + 6 = 26.
Marking: 2 marks for correct answer; 1 mark for correct method (10 + 10 + 6) but addition error.

14. Missing numbers: 61, 63, 64, 66, 68, 69
Explanation: The number line goes from 60 to 70 by ones. Fill in each missing integer: after 60 is 61, after 62 is 63, then 64, after 65 is 66, after 67 is 68, then 69, then 70.
Marking: 2 marks for all 6 correct; 1 mark for 4–5 correct.

15. Answer: 13 girls
Explanation: Total children = 28. Boys = 15. Girls = Total − Boys = 28 − 15 = 13.
Check: 15 + 13 = 28 ✓
Marking: 1 mark for correct equation (28 − 15), 1 mark for correct answer with unit "girls".

16. (a) 4th
(b) 7th
Explanation:
(a) Ordinal numbers in order: 1st, 2nd, 3rd, 4th, 5th.
(b) Counting backwards: 10th, 9th, 8th, 7th, 6th.
Marking: 1 mark each part.

Section C: Word Problems (2 × 2 marks + 1 × 3 marks = 7 marks)

17. Number equation: 36 + 24 = 60
Answer: 60 beads
Explanation: "Altogether" means add. Red beads = 36, Blue beads = 24. 36 + 24 = 60.
Working:
36
+ 24
———
60
Marking: 1 mark for correct equation, 1 mark for correct answer with unit.

18. Number equation: 45 − 18 = 27
Answer: 27 books
Explanation: "Taken away" means subtract. Start with 45, subtract 18. 45 − 18 = 27.
Working (regrouping):
45 → 3 tens 15 ones
− 18 → 1 ten 8 ones
———
27 → 2 tens 7 ones
Marking: 1 mark for correct equation, 1 mark for correct answer with unit.

19. Number equation: (3 × 10) − 12 = 18
or 10 + 10 + 10 − 12 = 18
Answer: 18 pencils
Explanation:
Step 1: Find total pencils. 3 boxes × 10 pencils = 30 pencils. (Or 10 + 10 + 10 = 30)
Step 2: Subtract pencils given away. 30 − 12 = 18 pencils left.
Marking: 1 mark for correct total (30), 1 mark for correct subtraction (30 − 12), 1 mark for final answer with unit "pencils".
Common mistake: Forgetting the second step and answering 30.
