Video Clip: A Careful Explanation
In this clip, Angela gives a careful and detailed explanation of the rules for order of operation in evaluating algebraic expressions. She then uses these rules to successfully solve both versions of her example.
She prepared for this by solving some puzzles with her partner and then writing about the process.
Angela used the video worksheet form, which allows her to choose the level of difficulty of her problems and gives her room to work out both versions of the problem. On page 2 of the worksheet, she can fill out a rubric to help her evaluate her performance.
