Description

This resource provides students an opportunity to practice adding and subtracting rational numbers by analyzing questions that have already been solved incorrectly. After finding the error, the students must explain in words what happened. Then they must solve 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.

The students were learning how to fix their own misconceptions and how to fix their own errors. The students also tended to learn from their own minor mistakes.
