1) Hook: The Mango Party 🍋🥭
Raju had 7 juicy mangoes 🍋 in his basket. He gave 3 mangoes to his friends. How many mangoes are left with Raju?
Let's find out by learning subtraction!
2) Core Concepts: What is Subtraction? ➖
Subtraction means taking away some objects from a group and finding out how many are left.
It is like saying: "I had some, I gave some away, now how many do I have?"
| Total Mangoes | Mangoes Given Away | Mangoes Left |
|---|---|---|
| 7 🥭 | 3 🥭 | 4 🥭 |
So, 7 mangoes minus 3 mangoes equals 4 mangoes left.
7 ➖ 3 = 4
Let's see another example:

Answer: 10 ➖ 2 = 8 ladoos left! 🍬🍬🍬🍬🍬🍬🍬🍬
