Primary 1 Mathematics Quiz - Multiplication Division (Answer Key)
Name: _________________________ Class: _________________________ Date: _________________________ Score: ________ / 20
Section A: Multiplication (Questions 1 - 5)
1. Write the multiplication sentence for the picture below.
Generated diagram for Q1.
Answer: 3 × 2 = 6
Explanation: There are 3 plates, and each plate has 2 apples. This means we have 3 groups of 2. In multiplication, "3 groups of 2" is written as 3 × 2. To find the total, we can add: 2 + 2 + 2 = 6. So, 3 × 2 = 6.
Marking Notes: 1 mark for the correct number sentence. Accept 2 × 3 = 6 if the student explains it as 2 apples on each of 3 plates (commutative property). The total must be 6.
2. Fill in the blank.
5 + 5 + 5 = ______ × 5
Answer: 3
Explanation: The addition sentence shows 5 added three times. This is the same as 3 groups of 5, which is written as 3 × 5. So the blank should be filled with 3.
Marking Notes: 1 mark for the correct answer.
3. There are 4 bags. Each bag has 3 pencils. How many pencils are there altogether?
Answer: 12 pencils
Explanation: We have 4 bags, and each bag has 3 pencils. This is 4 groups of 3. We can write this as 4 × 3. To find the total, we can add: 3 + 3 + 3 + 3 = 12. So, there are 12 pencils altogether.
Marking Notes: 1 mark for the correct answer with the correct unit (pencils).
4. What is 2 × 6?
Answer: 12
Explanation: 2 × 6 means 2 groups of 6, or 6 + 6. 6 + 6 = 12. So, 2 × 6 = 12.
Marking Notes: 1 mark for the correct answer.
5. Circle the correct answer.
7 + 7 + 7 + 7 = ?
A. 4 × 7 B. 7 × 7 C. 4 + 7
Answer: A. 4 × 7
Explanation: The addition sentence shows 7 added four times. This is the same as 4 groups of 7, which is written as 4 × 7.
Marking Notes: 1 mark for the correct option.
Section B: Division (Questions 6 - 10)
6. 12 sweets are shared equally among 3 children. How many sweets does each child get?
Answer: 4 sweets
Explanation: We are sharing 12 sweets equally among 3 children. This is a division problem: 12 ÷ 3. We can think: 3 × ? = 12. Since 3 × 4 = 12, each child gets 4 sweets.
Marking Notes: 1 mark for the correct answer with the correct unit (sweets).
7. Fill in the blank.
10 ÷ 2 = ______
Answer: 5
Explanation: 10 ÷ 2 means sharing 10 things into 2 equal groups. We can think: 2 × ? = 10. Since 2 × 5 = 10, the answer is 5.
Marking Notes: 1 mark for the correct answer.
8. 8 fish are put into 2 tanks. Each tank has the same number of fish. How many fish are in each tank?
Answer: 4 fish
Explanation: We are sharing 8 fish equally into 2 tanks. This is a division problem: 8 ÷ 2. We can think: 2 × ? = 8. Since 2 × 4 = 8, each tank has 4 fish.
Marking Notes: 1 mark for the correct answer with the correct unit (fish).
9. What is 15 ÷ 5?
Answer: 3
Explanation: 15 ÷ 5 means sharing 15 things into 5 equal groups. We can think: 5 × ? = 15. Since 5 × 3 = 15, the answer is 3.
Marking Notes: 1 mark for the correct answer.
10. Circle the correct answer.
20 ÷ 4 = ?
A. 4 B. 5 C. 6
Answer: B. 5
Explanation: 20 ÷ 4 means sharing 20 things into 4 equal groups. We can think: 4 × ? = 20. Since 4 × 5 = 20, the answer is 5.
Marking Notes: 1 mark for the correct option.

11. A box has 6 rows of stickers. Each row has 2 stickers. How many stickers are in the box?
Answer: 12 stickers
Explanation: We have 6 rows, and each row has 2 stickers. This is 6 groups of 2. We can write this as 6 × 2. To find the total, we can add: 2 + 2 + 2 + 2 + 2 + 2 = 12. So, there are 12 stickers in the box.
Marking Notes: 1 mark for the correct answer with the correct unit (stickers).
12. Mrs Tan has 18 oranges. She puts them equally into 3 baskets. How many oranges are in each basket?
Answer: 6 oranges
Explanation: We are sharing 18 oranges equally into 3 baskets. This is a division problem: 18 ÷ 3. We can think: 3 × ? = 18. Since 3 × 6 = 18, each basket has 6 oranges.

17. Fill in the blank.
______ ÷ 5 = 3
Answer: 15
Explanation: This question asks: "What number, when divided into 5 equal groups, gives 3 in each group?" We can think of it as a multiplication problem: 5 × 3 = 15. So, the missing number is 15. We can check: 15 ÷ 5 = 3.
Marking Notes: 1 mark for the correct answer.
18. Match the correct pairs. Write the letter in the box.
| Multiplication | Division |
|---|---|
| 2 × 4 = 8 | 8 ÷ 2 = 4 |
| 3 × 5 = 15 | 15 ÷ 3 = 5 |
| 4 × 2 = 8 | 8 ÷ 4 = 2 |
Which number sentence is the matching division for 3 × 5 = 15?
A. 15 ÷ 3 = 5 B. 15 ÷ 5 = 3 C. 5 × 3 = 15
Answer: A. 15 ÷ 3 = 5
Explanation: Multiplication and division are related. If 3 × 5 = 15, then we can also say 15 ÷ 3 = 5 (15 shared into 3 groups gives 5 in each group) and 15 ÷ 5 = 3 (15 shared into 5 groups gives 3 in each group). Both A and B are correct division sentences for 3 × 5 = 15. However, the table shows the matching pair as "3 × 5 = 15" and "15 ÷ 3 = 5", so the expected answer is A.
Marking Notes: 1 mark for the correct option. Accept B if the student can explain that it is also a correct related division fact, but guide them to the table's pairing.
19. A farmer has 9 ducks. He puts them into 3 pens equally. How many ducks are in each pen?
Answer: 3 ducks
Explanation: We are sharing 9 ducks equally into 3 pens. This is a division problem: 9 ÷ 3. We can think: 3 × ? = 9. Since 3 × 3 = 9, each pen has 3 ducks.
Marking Notes: 1 mark for the correct answer with the correct unit (ducks).
20. There are 4 trays. Each tray has 5 cups. How many cups are there altogether?
Answer: 20 cups
Explanation: We have 4 trays, and each tray has 5 cups. This is 4 groups of 5. We can write this as 4 × 5. To find the total, we can add: 5 + 5 + 5 + 5 = 20. So, there are 20 cups altogether.
Marking Notes: 1 mark for the correct answer with the correct unit (cups).
