The Physical Fitness Unit for grades K-12 of the Roslyn Public Schools in New York provides students with the knowledge to develop and maintain a level of health-related physical fitness both in and out of school that minimizes the risk of developing cardiovascular disease. The unit teaches the interrelationship of physical fitness, exercise, and nutrition, and prepares each student to assume his/her own responsibility for fitness and wellness. The design of the fitness unit includes a fitness evaluation that indicates the fitness range a student should attain to maintain a healthy status. Students formulate contracts for fitness attainment levels or establish individual fitness programs for fitness development in a noncompetitive and self-evaluative manner. This curriculum guide offers an overview of physical fitness units at the high school, middle school, and elementary school levels. It includes course outlines, fitness evaluation report forms, weekly workout program forms, a diet chart, a copy of a letter to parents introducing the fitness education program, a parent handout on physical fitness, fitness standards, and samples of certificates for use as student rewards.
