What is it?

Subtracting with pictures means taking away a certain number of items from a group and finding out how many are left, using visual aids. It helps us understand subtraction by seeing the items disappear, making it easier to count the remaining ones.

Simple Example

Quick Example

Imagine you have 5 delicious ladoos. If your younger sibling eats 2 of them, how many ladoos are left for you? You can draw 5 ladoos, then cross out 2, and count the rest.

Worked Example

Step-by-Step

Let's say you have 7 colourful kites for Makar Sankranti.
---Step 1: Draw 7 kites on a piece of paper.
---Step 2: Your friend flies 3 of your kites and they snap away. So, we need to take away 3 kites.
---Step 3: Cross out 3 of the kites you drew.
---Step 4: Now, count the kites that are not crossed out.
---Step 5: You will find there are 4 kites left.
So, 7 - 3 = 4.

Why It Matters
