This activity has 6 problems that are solving multi-step equations including fractions, distributive property, combining like terms, and variables on both sides. Students must find the error, state the step where the error was made, and what the error was. Students must then show the correct steps in solving the problems. This activity is definitely for those that have already previously practiced solving multi-step equations. They must know that it is okay if the constant is moved first and not the variable (2 problems have this). Students must be able to realize that moving the constant first is not necessarily the mistake, it's just another way to solve the problem.

This activity can be used as individual seat work, math center when reviewing, or have students pair up and take turns finding and explaining the error to each other and correcting the problems. If you only use one page, the activity could be used as an exit ticket. For very low level students, the whole activity make take a while. I would suggest leaving their paper one-sided so that they may finish at the same time as the other students.
