Addition and subtraction facts with 6 - fact families approach (1st grade math)

I show all the fact families with the sum of 6, organized into a table. Seeing the structure and the patterns in this manner helps develop number sense and helps children in the memorization work, also.

Then we drill the facts for a bit. The lesson also includes an exercise where we draw lines connecting facts from the same fact family, and a word problem.
