5 + 8 9 + 7 10 + 6 7 + 6

What facts might help you solve 9 + 7 and why? (Responses may vary. Possible response: 10 + 7 because 9 + 7 is close to 10 + 7.)
What facts might help you solve 7 + 6 and why? (Responses may vary. Possible response: I know 6 + 6. So 7 + 6 is more one more or 13.)
What facts help you solve other facts? (The facts that make ten, the doubles, and the facts like 10 + 8.)
