the same.

12 is a double
18 = 9 + 9
18 is a double
Is 16 a double?
What are the addends?
Is 2 a double?
What are the addends?

Doubles plus 1
• A doubles-plus-1 fact is a double plus 1 more.
• It has addends that are 1 apart.
6 is 1 more than
5. So 5 + 6 is 1
more than 5 + 5.
5 + 6 = 11
5 + 5 +1 = 11

Doubles plus 2
• A doubles-plus-2 fact is a double plus 2 more.
• It has addends that are 2 apart.
8 is 2 more than
6. So 8 + 6 is 2
more than 6 + 6.
8 + 6 = 14
2 + 6 + 6 = 14
