The Best of Brain Teasers, a compilation of the best brain teasers from Teacher Created Materials, provides many different ways to exercise and develop brain power. Each page can stand alone as a quick filler activity or reinforce a unit of study. The puzzles are designed to be solved by individual students, but they may also be made into transparencies for whole-class activities. In addition, they may be used for cooperative activities when given to teams of students to solve or answer.
