- Making Ten: Use the concept of making ten to simplify addition problems (e.g., 8 + 2 = 10).
Key Concepts
- Communative Property: The order of addends does not change the result (e.g., 2 + 3 = 3 + 2).
- Associative Property: The order in which addends are added does not change the result (e.g., (2 + 3) + 4 = 2 + (3 + 4)).
Examples
- 2 + 3 = 5
- 5 + 1 = 6
- 8 + 2 = 10
