What is Plus sign (+)?

The plus sign is like a friendly helper that makes things bigger by adding them together.

Imagine you have 2 candies and your friend gives you 3 more. You can use the plus sign to show this: 2 + 3. This means you now have 5 candies in total!

The plus sign is like a door that opens between two groups of things, letting them join together.

• If you see 4 + 1, it’s like putting 4 toy cars and 1 more toy car on the floor, you end up with 5 toy cars.
• When you write 7 + 2 = 9, it means when you combine 7 apples and 2 apples, you get 9 apples.

Think of counting steps. If you take 3 steps, then take 2 more steps, the plus sign helps you know how many steps you took in total: 3 + 2 = 5. You just walked 5 steps!

The plus sign is a simple but powerful tool that helps us count, group, and grow things, just like when we add more toys to our pile or more blocks to our tower!
