Instead of a lesson, we simply supply an activity to reinforce students’ knowledge of the distributive property. Students must be comfortable with negative numbers and the distributive property. If you are not sure how to use the activity, watch the video!

This excerpt covers some of the essentials of solving linear equations. It assume students can solve equations like 3 + x = 4, or 2z = 18, and shows how to use both the addition and multiplication properties of equality.
