This is a power point lesson that teaches how to simplify algebraic expressions. The lesson includes the standard, essential question, a spiral warm up, vocabulary, modeling with manipulatives and then steps, practice with increasing difficulty, and a closing review. In my power points, the answers pop in as you work through. This allows you to use the power points as a teaching tool for whole group, small group, individual assignment, practice, review, or even as a pre-view.
