The Growing Up Strong (GUS) program was developed for preschool through sixth grade students to promote mental and physical health and prevent substance abuse. The Spanish Bilingual Supplement to the kindergarten through third grade GUS materials also promotes respect for Spanish language and cultures. This document includes an English-language teacher's guide and Spanish-language duplication masters designed to be sent home with children to promote family involvement. The teacher's guide explains GUS's multicultural approach, discusses bilingual education, and presents guidelines for implementing GUS, involving the family, and integrating culturally sensitive learning experiences in the curriculum. Five learning experiences, including storytelling, native languages, stress management, community role models, and craft demonstrations are detailed, and books and resources are listed. The Spanish-language materials for at-home use include information sheets for family members on primary prevention and on the following topics: (1) believing in children; (2) permitting children to solve their own problems; (3) helping children to become better problem solvers; (4) permitting children to make decisions; (5) taking children to the grocery store; (6) taking responsibility around the house; (7) giving children some responsibility; (8) setting a good example of proper drug use; (9) valuing good health; and (10) explaining the benefits of putting away toys. Activity sheets for children include pages for children to color and to draw things that make them feel good, that make them angry, and that they do at home to help; sheets on which children can identify things that are bad for them; and sheets covering such activities as traveling through the neighborhood safely. Sample awards for children and GUS promotional materials are included. (AC)
