# Addition facts for sums with 6

This is a complete lesson with instruction and exercises about basic addition facts when the sum is 6, meant for 1st grade math. You can use the same ideas to teach other sums (sums with 7, 8, 9, 10, etc.) as well.

The video below shows many ideas and strategies for learning basic addition facts: grouping of sums as in this lesson, the 9-trick, doubles, and more.

1. Six hippos are grouped into two groups, in different ways. Write the addition sentences.
