How to introduce ‘Single Digit Addition, Subtraction and Counting ’ in an interesting way?

You may have observed your father or mother busy in planning about which items to buy in the market and estimating the total money needed to buy those items. How could they be planning? When they return, some money is spent with some change amount remaining.

• What helps them in planning?
• How does your mother/father calculate the total amount of all the items?

The Mathematical Knowledge of Addition, Subtraction, Multiplication and Division help us to estimate and plan our daily expenses. Learning them also helps us to analyse and understand ideas when we grow up.

The Magic of Addition and Subtraction

Imagine, Ramu, Joseph, Akbar and You are friends, planning to study Mathematics at your home on Sunday. Your father is going to a supermarket to buy some daily use materials. He asks you, whether you and your friends need some snacks to eat. Thinking of quantity you told your father to buy two Diary milk chocolates for every one of your friends. Now, how many chocolates should your father buy?

• How will you tell the total number of chocolates required for your friends to your father?
• What happens to the number of chocolates when your father buys for your friends too?

When your father buys chocolates for you and your friends he uses ‘Addition’ technique to get the total number of chocolates required. He calculates the total number of chocolates by adding chocolates required by each individual as – 2( for You) + 2( for Ramu) + 2(for Joseph) + 2( for Akbar) and gets total as 8 chocolates. Besides we always ADD or put TOGETHER things to get a larger amount of the same thing. This is called ADDITION and it is indicated as ‘+’ or verbally we call it ‘Plus’.

When your father went to the supermarket, suddenly Akbar’s father came to pick up Akbar as his Grandma has come home to see him. When Akbar left home you thought of chocolates that are going to waste and called up your father to tell the incident and buy fewer chocolates, as Akbar has left home. Now, what should your father do to bring the correct amount of chocolates excluding Akbar?
• Does the quantity of chocolate increase or decrease?
• Does your father add chocolate quantity or lesser the quantity?

As Akbar leaves the house, your father buys two less quantity of chocolates and it is the method of Subtraction. You father cuts out 2 quantities of chocolates out of 8 and brings 6 chocolates. This method is SUBTRACTION. In this method, we always take or cut out things to make less or lesser. It is indicated as ‘-’ and verbally called ‘Minus’.

Easy way to learn ‘Counting’

As there are many easy ways to learn to count, our age-old method of counting single digits is with the help of fingers or hands. Imagine, your 3 friends are sitting with you for lunch and you want to share the uncounted dairy milk shots in the lunch box with them. How will you count and share those shots?
• How will you remember your total number of Diary milk shots?
• How fingers and hands come in use?

You can count and share those Diary milk shots by counting individually using hands with the help of fingers. If you go on folding your finger for an individual shot you take out from your lunch box, the total number of shots you take out is identified using folded fingers in your hands. This helps to reduce confusion as we are relating each number to one finger.
Addition, Subtraction and counting also help to comprehend basic numbers. It acts as the framework for the mastery of Mathematics in our higher studies. Other than this we can know our number system through Addition, Subtraction and counting. Content related to the basic foundation must be taught or learn with utmost care as it acts as a base for much more learning in the future. Learning them with suitable learning aids like – Models, Visuals and Hands-on activities may help learners to learn easily and without misconceptions.
