This manual presents a schoolwide walking program that includes aerobic fitness information, curriculum integration, and walking tours. "Discover and Understand Carolina Kids by Walking" is D.U.C.K. Walking. An aerobic walking activity, D.U.C.K. Walking has two major goals: (1) to promote regular walking as a way to exercise at any age; and (2) to emphasize that good health begins with the help of family, friends, and school. Included in this manual are hints for the implementation and maintenance of a schoolwide walking program. Sample lesson plans provide guidance for 30 weeks of walking each year. In Level 1, classes accumulate "class miles" each week as they study about fitness walking. In Level 2, classes may relate the week's "class miles" to an imaginary tour of South Carolina. Further, students may relate imaginary tours to existing field trips and family trips. Level 3, "Going the Extra Mile," is an integrated approach to health, social studies, mathematics, language arts, science, physical education, and fine arts. Bulletin board hints, a sample recording sheet, examples of "extra mile" topics, "D.U.C.K. Call" (a sample newsletter), school and family walking activities, and family D.U.C.K. walks are appended.
