Description

This resource provides students an opportunity to practice simplifying algebraic expressions by combining like terms and utilizing the distributive property by analyzing questions that have already been simplified incorrectly. After finding the error, the students must explain in words what happened. Then they must simplify the problem correctly. Feel free to click on the preview to see the types of errors that students must analyze.

This resource would be great to have students do with partners, as a warm-up, a review before a quiz, as a station activity, an exit ticket, or for homework.

This product contains ten incorrectly solved problems.
