How do you explain related addition facts?
Overview
- We can also use these same three numbers in our math fact: 2, 1, and 3 to make a RELATED FACT. Save.
- 5 + 4 = 9. Related addition facts always have the same sum, or answer.
- 5 + 1 = 6 and 1 + 5 = 6. Here is another example:
- 2 + 8 = 10 and 8 + 2 = 10.
- 4 + 3 = 7.
- 5 8 3.
- __ + __ = 8.
- 5 + 3 = 8.
