Kits 37-40 of the bilingual (Spanish-English) language arts strand present reading, language analysis, and creative expression activities similar to those found in earlier kits of this spiral curriculum. Basic theme of unit 10 for grade three is communities around the world. Focus, objective, and materials are listed for each activity; assessment activities are included. Each kit presents one of the spiraling questions: who the individual is, what his alternatives are, how he can initiate change, and what the results of change are. Two pupil books, including materials from South and Central America, and support materials are also a part of unit 10. Kit content deals with reading for detail; written accent; oral and written activities in which students create their own stories; adaptations of "Martin Fierro"; biographies of Simon Bolivar and Benito Juarez; hyphens and contractions; oral, written, and nonverbal activities which express feelings; abbreviations; review of capital letters; oral and written activities about the concept of conservation of the ecological system; adaptation of a Jose Marti poem; a Puerto Rican folklore story; review of past, present, and future tenses; and writing advertisements. Each kit is designed for a two to three week instruction period. (RS)
