This activity is a fantastic way to review the skills involved with Pre-Algebra (linear equations, proportional and non-proportional relationships, Pythagorean Theorem) through the use of various high yield strategies. Students work collaboratively to "FInd the Error" among two people that are writing linear equations and finding slope from given points. There are even a couple questions at the end that involve the Pythagorean Theorem. Students then create their own "Find the Error" and trade with a partner to solve. I use this for test review, in stations, and for critical thinking whole group conversations. Students LOVE being the teacher and finding the errors!
