This teaching guide for a tobacco education curriculum at the sixth-grade level is a part of a coordinated K-12 educational support program for reducing smoking. It includes a tobacco curriculum matrix for grades K-12, sample teaching methods, concepts and objectives for grades 4-6, and a resource materials list. The basic instructional concepts for the sixth-grade level focus on helping students: (1) identify immediate and long-term effects of smoking on the body; (2) analyze those factors involved in personal decisions about smoking; (3) recognize the responsibility of the United States government in the production, sale and use of tobacco; and (4) understand that individuals can lead happy and productive lives without smoking. Objectives, teacher information, worksheets, and learning activities for each concept are provided.
