  1. Possible response: If I know the double, the near double is one or two more or less. For example: to solve 6 + 7, I know 6 + 6 = 12. So 6 + 7 is one more or 13.

U. Using Doubles

  1. 3 + 3 =
  2. 3 + 4 =
  3. 4 + 4 =
  4. 4 + 5 =
  5. 6 + 6 =
  6. 6 + 7 =
  7. 7 + 7 =
  8. 7 + 8 =
  9. 8 + 8 =
  10. 8 + 9 =
  11. 10 + 9 =
  12. 10 + 10 =
  1. Tell your neighbor a strategy for solving facts that are near doubles.
