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

3. If we have 2 apples
and someone gives us
3 more, we end up
with a total of 5
apples.

4. 2 apples
+ 3 apples
1 2 = 5 apples
3 4 5

5. 2 apples
+ 3 more apples
5 apples

6. 2 apples + 3 apples
1 2 3 4 5
equals 5
apples in all

7. 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.

8. 1 2 3 4
4 red apples
+ 2 yellow apples
5 6
= 6 apples

9. 4 red apples
+ 2 yellow apples
6 apples

10. 4 red apples + 2 yellow
apples
1 2 3 4 5 6
equals 6
apples in all
