This is a great activity to use when reviewing multi-step equations. Students have to find the error in each equation and then solve the equation correctly.

There's multiple ways you can use this assignment. One way is I assign each student a partner and give them a group number. Their group number matches the problem they will be solving. For example, if they are group two, they will be solving question two. Once each group solves their problem, each group goes up to the board one by one to explain the error and give the correct answer.
