Addition & subtraction facts within 10 - 1st grade math

I show all the fact families with the sum of 9, 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 a missing number exercise, an exercise where we compare simple addition and subtraction expressions, and word problems (with Mathy :^).

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

The lesson also includes an exercise of finding missing numbers (a little bit of algebra in disguise), and some word problems.

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 compare expressions ("alligator mouths") and draw lines connecting facts from the same fact family.
