Complete a – d. Work independently. Show your work in column 1.
Write your final answer in column two.
Fold your paper along the dashed line.

If your answers are the same, place a check mark in box three. If your answers are different, Write a sentence describing the error in column four, then solve the problem together.
Continue working, stopping to check in with your partner after your have each completed four problems.
