Total Marks: 25

---

Section A: Multiple Choice (4 marks)

1. What is the value of the digit 5 in the number 58?

• Answer: B. 50
• Explanation: In the number 58, the digit 5 is in the tens place. Each ten is worth 10, so 5 tens = 50. The digit 8 is in the ones place and is worth 8 ones.
• Marks: 1

2. Which number comes just after 69?

• Answer: B. 70
• Explanation: Counting on from 69 gives 70. "Just after" means the next whole number in the count.
• Marks: 1

3. Which set of numbers is arranged from the smallest to the greatest?

• Answer: C. 24, 31, 42
• Explanation: 24 is the smallest (2 tens), 31 is in the middle (3 tens), and 42 is the greatest (4 tens). When tens are different, the number with fewer tens is smaller.
• Marks: 1

4. How many pupils like blue?

• Answer: A. 3
• Explanation: The picture graph shows 3 smiley faces above "Blue". Each smiley stands for 1 pupil, so 3 pupils like blue.
• Marks: 1

---

Section B: Short Answers (12 marks)

5. Write "sixty-three" in numerals.

• Answer: 63
• Explanation: "Sixty" = 60 and "three" = 3, so 60 + 3 = 63.
• Marks: 1

6. (a) Digit in the tens place of 47: 4; (b) Digit in the ones place: 7

• Explanation: In 47, the first digit (4) tells us how many tens there are, and the second digit (7) tells us how many ones. So 47 = 4 tens + 7 ones.
• Marks: 1

7. Fill in the missing number: 20, 30, 40, ___, 60, 70

• Answer: 50
• Explanation: The pattern counts up by 10 each time. After 40 comes 50.
• Marks: 1

8. Number shown by 2 tens and 6 ones

• Answer: 26
• Explanation: 2 tens = 20, and 6 ones = 6. Adding them: 20 + 6 = 26.
• Marks: 1

9. Compare 35 and 53

• Answer: 35 < 53
• Explanation: Both numbers have 3 and 5 as digits, but the tens digit is different. 35 has 3 tens; 53 has 5 tens. Since 3 < 5, the number 35 is smaller.
• Marks: 1

10. Arrange 71, 17, 47 from greatest to smallest

• Answer: 71, 47, 17
• Explanation: Compare the tens digits first. 71 (7 tens) > 47 (4 tens) > 17 (1 ten).
• Marks: 1

11. Circle the even number(s): 12, 15, 18, 21, 24

• Answer: 12, 18, 24 (students should circle these)
• Explanation: Even numbers end in 0, 2, 4, 6 or 8. 12 ends in 2, 18 ends in 8, 24 ends in 4. The numbers 15 and 21 end in 5 and 1, so they are odd.
• Marks: 1

12. Mei Ling has 3 bags, 6 oranges in each bag. Total?

• Number sentence: 3 × 6 = 18
• Answer: 18 oranges
• Explanation: Multiplication can be read as "3 groups of 6". Counting: 6 + 6 + 6 = 18.
• Mark breakdown: 1 mark for the multiplication sentence, 1 mark for the final answer.
• Marks: 2

13. 20 stickers shared equally among 4 friends.

• Number sentence: 20 ÷ 4 = 5
• Answer: 5 stickers
• Explanation: Sharing equally means each friend gets the same amount. 20 ÷ 4 means how many groups of 4 are in 20, which is 5. Each friend gets 5 stickers.
• Mark breakdown: 1 mark for the division sentence, 1 mark for the final answer.
• Marks: 2

Section C: Show Your Working (9 marks)

14. Apples: 45 → sells 12 → receives 8. Total at end of day?

• Working:
  • Step 1: 45 − 12 = 33 (apples left after selling)
  • Step 2: 33 + 8 = 41 (apples after receiving 8 more)
• Answer: 41 apples
• Explanation: First, subtract the apples sold (12) from the original 45 to find what's left. Then add the new apples received (8). This is a two-step problem.
• Mark breakdown: 1 mark for the correct first number sentence, 1 mark for the correct second number sentence, 1 mark for the correct final answer with unit.
• Common mistake: Students sometimes do 12 + 8 = 20 first, then subtract from 45 to get 25, which is wrong because the operations happen in a different order than the problem describes.
• Marks: 3

15. What time is shown on the clock? (Hour hand at 4, minute hand at 6)

• Answer: 4 h 30 min (or 4:30, "half past four")
• Explanation: When the minute hand points to 6, it shows 30 minutes past the hour. The hour hand between 4 and 5 (closer to 4) confirms it is 4:30. At Primary 1 level, students are expected to read to 5-minute intervals.
• Mark breakdown: 1 mark for the hour (4), 1 mark for the minutes (30 min).
• Marks: 2

16. Length of the ribbon in cm

• Answer: 9 cm
• Explanation: Place the end of the ribbon at the 0 mark on the ruler. The other end lines up with 9. The measurement is read in whole centimetres, and the abbreviation "cm" must be written.
• Mark breakdown: 1 mark for the number 9, 1 mark for the correct unit "cm".
• Common mistake: Some students may misread 9 as 6 or 8; encourage them to start measuring from 0 each time.
• Marks: 2

17. Count the money: 1 × $5 + 2 ×$2 + 1 × 50¢

• Working:
  • Notes: $5 +$2 + $2 =$9
  • Coin: 50¢
  • Total: $9 + 50¢ =$9.50
• Answer: $9.50
• Explanation: First add the notes in dollars. Then add the coin. Convert 50¢ to $0.50 when writing the final total. The total is nine dollars and fifty cents.
• Mark breakdown: 1 mark for correct working, 1 mark for the correct final amount written with the $ symbol and two decimal places (or with ¢ symbol clearly).
• Marks: 2
