We have learned about Indian currency – ‘Indian rupee’.
All coins are made up of metals. In India, ₹1, ₹2, ₹5, ₹10 and ₹20 coins are in circulation.
- From the above, we can clearly see the denomination of coins is written on it. Therefore, we can easily identify the coins.
In India, ₹5, ₹10, ₹20, ₹50, ₹100, ₹200, ₹500, ₹2000 notes are in circulation.
- On each and every note, the denomination is printed on it. So, we can easily identify the value of the note.
Now, let’s learn how to count the money.
Here, there is only one coin of ₹1. So, the amount is ₹1.
Here, there are two coins of ₹1. Add the number 1 two times, we get:
1 + 1 = 2. So, the amount is ₹2.
Here, there is only one coin of ₹2. So, the amount is ₹2.
Here, there are two coins of ₹2. Add the number 2 two times, we get:
2 + 2 = 4. So, the amount is ₹4.
Adding ₹1 and ₹2, we get:
1 + 2 = 3. So, the total amount is ₹3.
Here, add the numbers 5 and 10, we get:
5 + 10 = 15
So, the total amount is ₹15.
How to count the money for buying something?
- We use the money for buying something that we want.
- So, we have to count the money equal to the cost of that thing. But we have a fixed value of currency coins and notes, so sometimes we can’t count the money exactly equal to the cost of that thing.
- To count the money, basically we use addition and subtraction.
A boy wants to buy a pencil that cost is ₹5.
How can he give the amount of ₹5?
He can count ₹5 in different ways.
Mini has Rs. 10 note, she wants to buy an ice-cream. The cost of ice-cream is Rs. 15. Can she buy the ice-cream with the money she has?
Mini has = ₹10
Cost of the ice-cream = ₹15
10 is less than 15. So, she has less amount of money.
Mini can’t buy the ice-cream.
Jenny wants to buy a balloon. She has a ₹20 note. When she gives that note to the shopkeeper, he returns ₹10. What is the cost of that balloon?
Jenny has spent some money buying a balloon which means she gave some amount of money to the shopkeeper. So, here we have to subtract that money.
We will do subtraction here.
She has now ₹10. She spent ₹10. So, the cost of a balloon is ₹10.
- When we spent some amount of money or take away some amount of money, to find the left amount we need to do subtraction.
- We use here, give and take money method.
