Family of Addition/Multiplication Facts
This lesson can assist students in learning their basic addition and multiplication tables from the 5s through the 25s by writing the Family of Facts for each set. The factors are generated randomly to enhance learning.
Click in the box to check answers. As long as the first pair of lines match and the second pair match, the student can check their own work.
Every operation has three related facts:
1) its commutative operation
2) its two compatible inverses
Keywords: Division, Sharing, Grouping, Equal Parts
