This teacher's manual provides general and specific guidelines for use of Teams-Games-Tournaments (TGT) Life Science Curriculum materials at the junior high-middle school level. TGT is an innovative instructional model which focuses on the learning of basic skills, information, and concepts, by rewarding students in small teams rather than at the individual level. The "games" component consists of a series of learning games; "tournaments" involve weekly sessions in which each student competes with other students of comparable achievement level on other teams; ultimately, individual scores are converted to team scores and winning teams are declared. The manual includes worksheets and gamesheets covering 47 learning objectives classified under these basic units: structure of matter, general equipment, life processes, genetics, health, ecology, and careers.
