Basic Concepts
In a nutshell: Addition means putting things together to make a bigger number.
## Putting Things Together
Addition means bringing groups together to find out how many there are in total. We use the plus sign (+) to show addition.
## How Addition Works
If you have 2 red balls and get 3 more, you have 2 + 3 balls altogether. Addition tells you the new total.
## Ways to Add
- Use fingers
- Draw dots or pictures
- Use number lines
## Addition in Daily Life
We add things all the time, like when collecting stickers or sharing snacks with friends.
### Addition Sentences
An addition sentence looks like this: \( 4 + 2 = 6 \). The numbers you add together are called addends, and the answer is the sum.
### Real-World Connections
Addition helps you figure out how many toys you have after getting a new one, or how many candies you and a friend have together.
a + b = c
Examples
- Adding 3 toy cars to 2 toy cars: 3 + 2 = 5.
- Adding 1 apple to a basket of 4 apples: 1 + 4 = 5.
