INTRODUCE FREIEND CONCEPT

At ALOHA we have 2 friends to solve our mathematical problems. One is small friend and the other one is big friend.

At first, we will learn about our small friend which is 5.

SHOW PROBLEM

Suppose I have 1 if I want to add 4 with 1 in fingering, I can’t add because I don’t have 4 fingers. So, this is a problem.

In our personal life if we face problem we takes the help of a friend. Friends help us in all stage. Like us, in ALOHA we also have some friends who help us to do addition and subtraction.

TWO FRIENDS

In ALOHA there are two friends. One is small friend and another one is big friend

Small friend is 5

Big Friend is 10

Today we will know about our small friend 5. Later we will know about 10.

WHO WILL GET THE HELP OF “5”?

Think about a 5th grade student, whom s/he can help in his or her study. Obviously lower grade from fifth grade and they are grade 4, grade 3, grade 2, grade1.

Like a 5th grade student here our small friend 5 can also help 4, 3, 2, 1.

5 will help them whenever this group faces any problem. So, 5 is their common friend or captain of this group.

CLOSE FRIEND

Suppose you have 4 chocolates and you want to make it 5, then how many chocolates you need add? Obviously 1.

So, we can say 4 & 1 are close friend or best friend (4, 1).

Similarly, you have 3 chocolates and you want to make it 5, then how many chocolates you need add? Obviously 2.

So, we can say 3 & 2 are close friend or best friend (3, 2)

4’s Friend is 1 because 4 & 1 makes 5. In this way 3 &2 are friend, 2 & 3 are friend and 1’s friend is 4.

(4, 1) (3, 2) (2, 3) (1, 4)
