# Multiplication-Repeated Addition

Repeated addition is also known as multiplication. If the same number is repeated then in short we can write that in the form of multiplication.For example : 2 + 2 + 2 + 2 + 2

Here 2 is repeated 5 times so in short we can write this addition as 2 x 5.

If there are 8 friends and 2 balloons are given to each friend then 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 16 This repeated-addition can be written in the form of multiplication as 8 x 2 = 16 |

**Using Movement to Get Ready For Multiplication**

**Example 1:**Teacher asks

**10**children to join the game. She explains that they run with the music and listen to the instruction when it stops.

**Music Stops**

Get together in 2's. How many groups?

**Solution :**2 + 2 + 2 + 2 + 2 = 10

The Children count

**5**.

So

**5**groups of

**2 = 10**

**Music Starts**

After some seconds

**Music Stops**

Get together in 5's. How many groups?

**Solution :**As the number of children are 10 so 2 groups of 5. 5 + 5 = 10

The Children count

**2**.

So

**2**groups of

**5 = 10**

_____________________________________________________________________

**Example 2 :**

Each contains 5 leaves and there are 4 groups.

5 + 5 + 5 + 5 = 20

In short 4 times 5 = 4 x 5 = 20

_____________________________________________________________________

**Example : 3**

Each necklace contains 5 beads and there are 2 groups.

5 + 5 = 10

In short 2 times 5 = 2 x 5 = 10

**Practice**

Q.1 Write the number of groups :

**•**6 + 6 ----> 2 groups of 6 ( 1st one is done for you)

**•**3 + 3 + 3

**•**4 + 4 + 4 + 4

**•**10 + 10

**•**9 + 9 + 9 + 9 + 9

Q.2 Write the following using multiplication.

**•**7 + 7 + 7

**•**11 + 11 + 11

**•**2 + 2 + 2 + 2 + 2 + 2 + 2 + 2

**•**15 + 15

**•**13 + 13 + 13
