This elementary school curriculum guide, the subject of a citywide teach-in in the New York City schools, provides facts, lessons, and learning activities designed to provide information about and to prevent the use of crack, a form of cocaine. The lessons are divided into two groups, one for grades K-3 and the other grades 4-6. The primary curriculum consists of four interdisciplinary lessons: (1) You Are What You Eat: How Foods Help Us; (2) Dangers in the House; (3) Dangers in Your Medicine Cabinet; and (4) Pinocchio Goes to Pleasure Island: A Story of Peer Pressure. These lessons provide a framework for teaching about substance abuse if the children raise this problem. The lessons for grades 4-6 focus on the facts about crack, the reasons people give for using crack, how to say no, and on deciding whether to use drugs: titles of lessons are (1) Pharmacology of Crack: What It Does to the Body; (2) Reasons Given for Drug Abuse; and (3) Consequences of Using Crack. Follow-up activities for grades 4-6, a fact sheet for teachers, a poster, and an evaluation form are also included. (KH)
