This activity can be used in rotations for small groups or partners. Students have to sort out the problems into 2 categories: True and False. However, they need to write out corrections "fix-its" next to the false problems. When all of their problems are sorted and "fix-its" are written out, they should check the answer key to make sure they have completed their math work correctly. True/ False & Fix-It encourages students to recognize mistakes and practice correct mathematical work.
