This lesson is meant to be used as guided notes for a whole class, with an algebra tile activity at the end.
Students begin by learning how to add polynomials. They are taught how to model this sum using algebra tiles, and then they find a few more sums. Next, they do the same thing, except with differences of polynomials. After the guided notes is a 2 page algebra tile activity/assignment/assessment.
The last 2 pages are a copy of the key for the guided notes.
