The last of five booklets on specific sports instruction in Special Olympics presents information on teaching cross country skiing to mentally retarded persons. The approach uses goals, short term objectives, task analyzed activities, assessments and teaching suggestions for individualizing and integrating the sports skills instruction with other curriculum areas. Instruction is designed to be given by volunteers. Initial sections discuss hints for being a good teacher, organizational suggestions, and information on clothing, equipment and a dryland training program. A skills assessment determines the student's present functioning level. The following specific skills are addressed: ready position, recovery, forward walking, star turns, climbing, straight run, wedge, turns, diagonal stride, and double poling. Sections on rules and safety and racing conclude the guide. (CL)
