Presented are units prepared by the participants of Arizona's Migrant Teacher Institutes which were organized to train participants in the implementation of individualized instruction. Part I describes what a learning center is, how to begin and evaluate learning centers, and the distinguishing features between a teaching unit and a resource unit. Suggested learning center activities presented on the topic of food include: a language center featuring show and tell and use of the telephone to order groceries; a math center with play money to buy groceries and estimating exercises; a science or health center using food and food pictures to distinguish likenesses and differences and to classify foods by taste; an art center with macaroni art; a music center with songs about food; and an audio-media center using food related films and tape recordings of children eating food. Part II presents six complete resource units; collections of suggested teaching and learning experiences and materials are organized around a selected topic or area. Each unit includes goals, objectives, specific teacher-directed motivational activities, committee and group work projects permitting students to make alternative topic choices and approaches, pre- and post-unit evaluative measures, and a unit-concluding activity. The grade K-3 units focus on animals, dinosaurs, and community awareness. The grade 4-8 unit topics concern the migrant worker, air and water pollution, and life in the middle ages. (NEC)
