Amma made laddoos in 4 rows with 5 in each row. Do you need to count every laddoo one by one?

Think about this for a moment before you start.

Turn the scene, tap the objects and answer. Easy, Medium and Challenge are the three checkpoints.

Multiplication is quick adding of equal groups. 4 rows of 5 is 5 + 5 + 5 + 5 = 20, written 4 × 5 = 20.

Division is sharing equally or making equal groups. 12 bananas shared by 3 children gives 4 each: 12 ÷ 3 = 4.

Multiplication and division are partners: if 3 × 4 = 12, then 12 ÷ 3 = 4 and 12 ÷ 4 = 3. Skip counting (4, 8, 12, …) helps with both.

🇮🇳 Example from India

In a school bus, seats are in rows of 3. 8 rows have 3 × 8 = 24 seats, so 24 children can sit.

⚠️ Common mistake

✗ Sharing 12 sweets among 3 friends means each gets 3.
✓ Each friend gets 4: deal one at a time until all 12 are given. 12 ÷ 3 = 4.

Play Medium and Challenge in the 3D scene. The bars show how many you got right the first time.

Try this at home or at school, then check the suggested answer.

Scenario A packet has 6 biscuits. You buy 4 packets for a class party. How many biscuits do you have?

Show a suggested answer

4 × 6 = 24 biscuits (6 + 6 + 6 + 6).

🧪 Try this activity

Arrange buttons or bottle caps in rows and columns. Write the multiplication fact for each arrangement, then share them equally among family members.

Think, then answer in your own words. Your notes stay on this device.

Observation In the 3D scene, look at the tray of laddoos. How can rows and columns help you count faster?

My answer

Show a suggested answer

Count one row, then multiply by the number of rows: 3 rows of 4 is 3 × 4 = 12, without counting each one.

Explain / create Show a friend how 15 ÷ 3 and 3 × 5 are connected, using 15 seeds.

My answer

Show a suggested answer

Share 15 seeds into 3 equal groups: 5 in each, so 15 ÷ 3 = 5. Put the groups back together: 3 groups of 5 is 3 × 5 = 15.
