Addition is the process of putting items together and counting the total number in the set.

If we have 2 apples and someone gives us

3 more, we end up with a total of 5

apples.

2 apples

1 2

3 4 5

+ 3 apples

= 5 apples

2 apples

+ 3 more apples

5 apples

1 2 3 4 5

2 apples + 3 apples

equals 5 apples in all

If we need 6 apples for a pie, we might

use 4 red apples and 2 yellow apples. This would give us a total

of 6 apples.

1 2 3 4

4 red apples

5 6 + 2 yellow apples

= 6 apples

4 red apples

+ 2 yellow apples

6 apples

1 2 3 4 5 6

4 red apples + 2 yellow apples

equals 6 apples in all
