What are you looking at?

I am counting the wheels of auto- rickshaws and bicycles by adding the number of their wheels. But I missed the cars as they had started moving.

Ok! I will show you a way of finding the total number of wheels. There were 7 cars and each car had 4 wheels, so the total number of wheels is 7 times 4, means 28.

How did you do it Ramya? Can you please explain?

Discuss the importance of traffic rules with children.

Let us Do

Let us see

There are 4 bicycles. Each bicycle has 2 wheels.

Total wheels = 2 + 2 + 2 + 2 = 8

We are adding 2 for 4 times.

So, 4 times 2 is also 8 or 4 groups of 2 give 8.

You know, times can be written as '×'.

4 × 2 = 8

Now! This is easy. Let me do this for autorickshaws now.

Number of autorickshaws = 2

Each auto has 3 wheels.

Total wheels = 3 + 3 = 6

2 times 3 is 6 or 2 groups of 3 is 6.

2 × 3 = 6

Let us do it for cars.

Number of cars =

Number of wheels in each car =

Total wheels = + + + + + + =

times 4 is

7 groups of is

× =

How many fours are you adding? ____ We can write it as 7 fours are 28.

Let us Do

Number of butterflies =

Number of wings in each butterfly =

Total number of wings = + + = 3 groups of is

times 2 is 6

3 twos are

× =

Number of octopuses =

Number of legs in each octopus =

Total number of legs = + =

2 groups of is

2 times is 16

2 eights are

× =
