ABSTRACT
Review of material seems to be an essential part of effective learning. Teachers are truly creative thinkers and use many wonderful ways to review. Puzzle sheets can be used to keep the process from becoming tedious. The purpose of 'Pairs Check With a Switch' is to encourage students to talk together about concepts being learned, to review material for a soon-to-be-given test. Students should check their individual papers and reflect on how team decisions were made, especially when team answers were incorrect and individual answers were correct. At an appropriate time, the students are instructed to form their collaborative teams. The "4" mode requires the group to thoroughly discuss the review assignment with emphasis on the words justify, explain, defend, prove or demonstrate. For best results, the teams should have been formed by the teacher into groups that are the most likely to produce excellence.
