Total Marks: 30

Section A: Multiple Choice Questions (10 marks)

1. Which of the following coins has the smallest value? [1]

Answer: (4) 5-cent coin

Explanation: Singapore coins in circulation for Primary 1 are 5¢, 10¢, 20¢, 50¢, and $1. The 5-cent coin has the smallest value.

Common mistake: Some students may think the 10-cent coin is smaller because it is physically smaller than the 5-cent coin. Remind students that value is not determined by physical size.

---

2. How many 10-cent coins make $1? [1]

Answer: (2) 10

Explanation: $1 = 100¢. Each 10-cent coin is worth 10¢.
100¢ ÷ 10¢ = 10 coins.

Teaching note: This reinforces the conversion between dollars and cents (100¢ = $1) and skip counting by 10s.

---

3. Look at the coins below. What is the total amount? [1]

Answer: (3) 85¢

Explanation: Add the values of all coins shown:
50¢ + 20¢ + 10¢ + 5¢ = 85¢

Step-by-step:
50 + 20 = 70
70 + 10 = 80
80 + 5 = 85

---

4. Ali has the following notes and coins. How much money does he have? [1]

Answer: (2) $3.70

Explanation: Add the values:
$2 +$1 + 50¢ + 20¢ = $3 + 70¢ =$3.70

Step-by-step:
$2 +$1 = $3 50¢ + 20¢ = 70¢$3 + 70¢ = $3.70

---

5. Which set of coins shows 65¢? [1]

Answer: (1) 50¢, 10¢, 5¢

Explanation: Check each option:
(1) 50 + 10 + 5 = 65¢ ✓
(2) 50 + 20 = 70¢ ✗
(3) 20 + 20 + 20 + 5 = 65¢ but uses 4 coins (not fewest) ✗
(4) 50 + 10 + 10 = 70¢ ✗

Teaching note: Option (1) uses the fewest coins (3 coins) to make 65¢, which is the standard way to represent an amount.

---

6. Siti wants to buy a pencil that costs 80¢. She has the coins shown below. How much more money does she need? [1]

Answer: (1) 5¢

Explanation: Siti has: 50¢ + 20¢ + 5¢ = 75¢
Pencil costs: 80¢
Amount needed: 80¢ - 75¢ = 5¢

---

7. John has $2. He buys an eraser for 60¢. How much change does he get? [1]

Answer: (3) $1.40

Explanation: $2 = 200¢ Cost of eraser = 60¢ Change = 200¢ - 60¢ = 140¢ =$1.40

Alternative method:
$2.00 -$0.60 = $1.40

---

8. Which of the following is the same as $1.50? [1]

Answer: (1) 150¢

Explanation: $1 = 100¢, so$1.50 = 100¢ + 50¢ = 150¢

Common mistake: Students may choose (3) 105¢ by incorrectly placing the decimal. Emphasise that $1.50 means 1 dollar and 50 cents, not 1 dollar and 5 cents.

---

9. Mary has three 20-cent coins and two 10-cent coins. How much money does she have? [1]

Answer: (3) 80¢

Explanation:
3 × 20¢ = 60¢
2 × 10¢ = 20¢
Total = 60¢ + 20¢ = 80¢

---

10. The price of a toy car is $4.50. Which of the following shows the correct amount using notes and coins? [1]

Answer: (2) One $2 note, two$1 coins, and one 50-cent coin

Explanation: Check each option:
(1) $2 +$2 + 50¢ = $4.50 ✓ (but uses two$2 notes, not standard)
(2) $2 +$1 + $1 + 50¢ =$4.50 ✓
(3) $1 +$1 + $1 +$1 + 50¢ = $4.50 ✓ (uses four$1 coins)
(4) $2 +$1 + 50¢ + 50¢ = $4.00 ✗

Note: Options (1), (2), and (3) all make $4.50. Option (2) is the most standard representation using available denominations. In Singapore context,$2 notes and $1 coins are commonly used.

---

Section B: Short Answer Questions (10 marks)

11. Count the money shown below and write the total amount. [2]

Answer: $1.45 or 145¢

Marking:

• Correct total: 1 mark
• Correct unit ($ or ¢): 1 mark

Working:
50¢ + 50¢ = 100¢ = $1 20¢ + 10¢ + 10¢ = 40¢ 5¢ = 5¢ Total =$1 + 40¢ + 5¢ = $1.45

---

12. Fill in the blanks with the correct amount. [2]

(a) $1 = 100¢** [1] **(b)$3.50 = 350¢ [1]

Explanation:
(a) 1 dollar = 100 cents (basic conversion)
(b) $3 = 300¢, 50¢ = 50¢, so$3.50 = 300¢ + 50¢ = 350¢

Common mistake: For (b), students may write 35¢ or 305¢. Remind them that $3.50 = 3 dollars and 50 cents = 300¢ + 50¢.

---

13. Circle the coins that make 95¢. Use the fewest number of coins possible. [2]

Answer: Circle the 50¢ coin, two 20¢ coins, and one 5¢ coin. (4 coins total)

Marking:

• Correct coins circled: 1 mark
• Fewest coins used (4 coins): 1 mark

Working:
Start with the largest coin: 50¢
Remaining: 95¢ - 50¢ = 45¢
Next largest: 20¢ (use two) → 45¢ - 40¢ = 5¢
Last: 5¢
Total coins: 1 + 2 + 1 = 4 coins

Alternative using more coins (not fewest): 50¢ + 20¢ + 10¢ + 10¢ + 5¢ = 5 coins

---

14. Look at the price tags below. [2]

(a) Which item costs the most? Book [1]
(b) How much more does the book cost than the ruler? $1.70 [1]

Working for (b):
Book = $2.50 = 250¢ Ruler = 80¢ Difference = 250¢ - 80¢ = 170¢ =$1.70

Alternative: $2.50 -$0.80 = $1.70

---

15. Ahmad has $5. He buys a drink for$1.20 and a bun for 80¢. How much money does he have left? [2]

**Answer: $3.00** (or$3)

Marking:

• Correct total spent: 1 mark
• Correct change: 1 mark

Working:
Drink = $1.20 Bun = 80¢ =$0.80
Total spent = $1.20 +$0.80 = $2.00 Money left =$5.00 - $2.00 =$3.00

---

Section C: Word Problems (10 marks)

16. Lily has two $2 notes and three 50-cent coins. She wants to buy a storybook that costs$5. Does she have enough money? If yes, how much will she have left? If no, how much more does she need? [2]

Answer: Yes, she has enough. She will have $0.50 (50¢) left.

Marking:

• Correct total money Lily has: 1 mark
• Correct comparison and final answer: 1 mark

Working:
Two $2 notes =$4.00
Three 50-cent coins = 3 × 50¢ = 150¢ = $1.50 Total =$4.00 + $1.50 =$5.50
Storybook = $5.00$5.50 - $5.00 =$0.50 left

---

17. A packet of stickers costs 65¢. Tom buys 2 packets. He gives the cashier $2. How much change does he get? [2]

Answer: 70¢

Marking:

• Correct total cost: 1 mark
• Correct change: 1 mark

Working:
Cost of 1 packet = 65¢
Cost of 2 packets = 65¢ × 2 = 130¢ = $1.30 Money given =$2.00 = 200¢
Change = 200¢ - 130¢ = 70¢

---

18. Mrs Tan has $10. She buys 3 apples at 60¢ each and a loaf of bread for$2.50. How much money does she have left? [2]

Answer: $5.70

Marking:

• Correct cost of apples: 1 mark
• Correct total spent and change: 1 mark

Working:
3 apples = 3 × 60¢ = 180¢ = $1.80 Bread =$2.50
Total spent = $1.80 +$2.50 = $4.30 Money left =$10.00 - $4.30 =$5.70

---

19. Peter has four 20-cent coins and three 10-cent coins. Jane has two 50-cent coins. Who has more money? How much more? [2]

Answer: Peter has more money. He has 10¢ more than Jane.

Marking:

• Correct amount for each person: 1 mark
• Correct comparison and difference: 1 mark

Working:
Peter: 4 × 20¢ = 80¢; 3 × 10¢ = 30¢; Total = 110¢ = $1.10 Jane: 2 × 50¢ = 100¢ =$1.00
Peter has more.
Difference = 110¢ - 100¢ = 10¢

---

20. The canteen sells the following items: [2]

Answer: $0.70 (or 70¢)

Marking:

• Correct total cost: 1 mark
• Correct change: 1 mark

Working:
Noodles = $1.50 Ice Cream = 60¢ =$0.60
Total spent = $1.50 +$0.60 = $2.10 Money Sam has =$3.00
Money left = $3.00 -$2.10 = $0.90

Wait, let me recalculate:
$3.00 -$2.10 = $0.90 (90¢)

Correction: Answer should be $0.90 (90¢)

Working (corrected):
Noodles = $1.50 Ice Cream = 60¢ =$0.60
Total = $1.50 +$0.60 = $2.10$3.00 - $2.10 =$0.90

Final Answer: $0.90 (or 90¢)
