Let’s add. What is the sum?
Reveal
6 + 6 = 12.
The sum is 12. There are 12 dots.
3. Bring It Together
When you use doubles, the two addends are the same. Doubles can help with addition.
0 + 0 = 0
1 + 1 = 2
2 + 2 = 4
3 + 3 = 6
4 + 4 = 8
5 + 5 = 10
6 + 6 = 12
7 + 7 = 14
8 + 8 = 16
9 + 9 = 18
10 + 10 = 20
