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
So multiplication is easier than repeated-addition.

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
