About Fact Families
What this skill is
Fact families showcase the four related addition and subtraction equations created from three numbers (e.g., 3, 5, 8 produce 3+5=8, 5+3=8, 8-3=5, 8-5=3).
When children learn it
Fact families are taught in 1st and 2nd grade, aligned to Common Core standard 1.OA.B.4.
Teaching Tips
- Use fact family triangles with the largest total number at the top roof.
- Remind children that subtraction equations must start with the largest total.
Common Mistakes
- Introducing a fourth random number not in the original fact family trio.
- Putting the largest number first in addition sentences instead of subtraction.
