Funded by combined Title I Migrant and Title IV Civil Rights Act funds, this guide on six major themes dealing with Puerto Rico was developed primarily for use by teachers in elementary and secondary schools. The guide is designed to provide teachers and students with a better understanding of Puerto Rican and culture. Although the publication was originally developed for use in migrant education programs, its units can serve as a resource for use in bilingual, social studies, or cross-cultural programs at the elementary and secondary levels. The "Overview" section summarizes and highlights key items relating to the major themes. "Objectives and Activities" provide a framework within which the units can be used. The "Teachers' Aids" identify supplemental resources which are further developed in the bibliography. The bibliography also includes annotations of other books and articles pertaining to Puerto Rican history and culture. Grade levels, publishers, and publication dates (where available) are noted for each entry. In addition, a list of publishers' addresses is provided. (Author/JM)
