Subject: Mathematics
Level: Primary 1
Paper: Practice Paper 3 (Numbers up to 100)
Total Marks: 40
Section A: Multiple Choice Questions (10 marks)
1. Answer: (3) 18 [1]
Count the stars in the diagram. There are 3 rows of 6 stars each. 6 + 6 + 6 = 18 stars altogether.
2. Answer: (3) 50 [1]
In the number 58, the digit 5 is in the tens place. Its value is 5 tens = 50. The digit 8 is in the ones place with value 8.
3. Answer: (2) 24 [1]
Compare the tens digits first: 42 has 4 tens, 24 has 2 tens, 34 has 3 tens, 43 has 4 tens. The smallest tens digit is 2, so 24 is the smallest number.
4. Answer: (2) 18 [1]
The pattern increases by 2 each time: 12, 14, 16, 18, 20. The missing number is 16 + 2 = 18.
5. Answer: (2) 49 [1]
The number just before 50 is 49 (one less than 50).
6. Answer: (2) 7 [1]
In the number 73, the digit 7 is in the tens place and the digit 3 is in the ones place.
7. Answer: (1) 56, 65, 67, 76 [1]
Compare tens digits first: 56 (5 tens), 65 (6 tens), 67 (6 tens), 76 (7 tens). For 65 and 67 (both 6 tens), compare ones: 5 < 7, so 65 < 67. Order: 56, 65, 67, 76.
8. Answer: (1) 39 [1]
3 tens = 30, 9 ones = 9. 30 + 9 = 39.
9. Answer: (2) 80 + 5 [1]
85 = 8 tens and 5 ones = 80 + 5.
10. Answer: (2) 40 [1]
4 boxes × 10 pencils each = 40 pencils altogether. (10 + 10 + 10 + 10 = 40)
Section B: Short Answer Questions (18 marks)
11. Numerals: 27
Words: twenty-seven [2]
Count the apples carefully. There are 27 apples. In numerals: 27. In words: twenty-seven (hyphen between twenty and seven).
12. (a) 46 = 4 tens 6 ones
(b) 80 = 8 tens 0 ones [2]
For (a): 46 has 4 in the tens place (value 40) and 6 in the ones place (value 6).
For (b): 80 has 8 in the tens place (value 80) and 0 in the ones place. Even though there are no ones, we write 0 ones to show the place value.
13. (a) 54 > 45
(b) 67 < 76
(c) 89 = 89
(d) 32 > 23 [2]
Compare tens digits first. If tens are equal, compare ones digits.
(a) 5 tens > 4 tens, so 54 > 45.
(b) 6 tens < 7 tens, so 67 < 76.
(c) Both numbers are 89, so they are equal.
(d) 3 tens > 2 tens, so 32 > 23.
14. (a) 5, 10, 15, 20, 25, 30
(b) 50, 45, 40, 35, 30, 25 [2]
(a) Pattern increases by 5 each time (counting in fives). 15 + 5 = 20, 20 + 5 = 25.
(b) Pattern decreases by 5 each time. 40 - 5 = 35, 35 - 5 = 30.
15. Number line: 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70 [2]
Fill in the missing numbers by counting forward by 1 from 60 to 70. Each tick represents the next whole number.
16. (a) Greatest: 61
(b) Smallest: 39 [2]
Compare all four numbers: 48, 52, 39, 61. Look at tens digits: 39 has 3 tens (smallest), 61 has 6 tens (greatest). So 39 is smallest, 61 is greatest.
17. (a) 1 more than 69 is 70
(b) 1 less than 40 is 39
(c) 10 more than 25 is 35
(d) 10 less than 73 is 63 [2]
(a) 69 + 1 = 70 (crossing the tens boundary).
(b) 40 - 1 = 39 (crossing the tens boundary).
(c) 25 + 10 = 35 (add 1 ten).
(d) 73 - 10 = 63 (subtract 1 ten).
18. Working:
Total children = 36
Number of boys = 15
Number of girls = 36 - 15 = 21
Answer: 21 girls [2]
This is a subtraction problem: total = boys + girls, so girls = total - boys. 36 - 15 = 21. Check: 15 + 21 = 36 ✓
Section C: Word Problems (12 marks)
19. (a) Working:
Cookies on Monday = 45
Cookies on Tuesday = 28
Total = 45 + 28 = 73
Answer: 73 cookies [3]
Add the two amounts: 45 + 28. Add ones: 5 + 8 = 13 (1 ten 3 ones). Add tens: 4 + 2 + 1 (carried) = 7. Total = 73.
(b) Working:
Difference = 45 - 28 = 17
Answer: 17 more cookies [3]
Subtract Tuesday's cookies from Monday's: 45 - 28. Subtract ones: 5 - 8 (cannot, so regroup 1 ten from 4 tens → 15 - 8 = 7). Subtract tens: 3 - 2 = 1. Difference = 17. Mrs Tan baked 17 more cookies on Monday.
20. (a) Working:
Stickers to brother = 19
Stickers to sister = 12
Total given away = 19 + 12 = 31
Answer: 31 stickers [3]
Add the stickers given to brother and sister: 19 + 12. Add ones: 9 + 2 = 11 (1 ten 1 one). Add tens: 1 + 1 + 1 (carried) = 3. Total = 31.
(b) Working:
Stickers Ali had at first = 64
Stickers given away = 31
Stickers left = 64 - 31 = 33
Answer: 33 stickers [3]
Subtract total given away from original amount: 64 - 31. Subtract ones: 4 - 1 = 3. Subtract tens: 6 - 3 = 3. Ali has 33 stickers left. Check: 31 + 33 = 64 ✓
