Use DPP item R to practice the addition facts in Group E. Students will need connecting cubes and number lines readily available.

  1. 8 + 4 = 10 + 2
  2. 9 + 5 = 10 + 4
  3. 13 = 4 + 9
  4. 13 = 8 + 2 + 3
  5. 7 + 3 + 2 = 7 + 5
  6. 19 + 1 + 3 = 10 + 10 + 3
  7. Answers will vary. Possible strategy: I counted up from 9 on the number line to 13. It was 4 hops to get to 13.
