Communities around the world is the theme of unit 10 of a bilingual social science strand for grade three. Inquiry strategies in both cognitive and affective domains serve as instruments to reach objectives of learning and assessment activities in kits 37-40. Each kit focuses on one of the spiraling questions of who the individual is, what his alternatives are, how he can initiate change, and what the results of change are. Content sources are stories, U.S. and world maps, dramatizations, research work, group reports, guided discussion, and the child's experiences. Focus, objective, and materials for each activity are given in English and Spanish; teacher instructions are in Spanish. Kits cover the concepts of what being bilingual/bicultural means and of interdependence, cooperation, values and societal control; extended family values common to three ethnic groups (Mexicans, Puerto Ricans and Cubans); beginnings of Indians in America; concepts of tradition and causality; the Spanish explorer Balboa; other explorations; a child planned expedition; concepts of power, conflict, and differences; origin of customs; identification of cultural elements related to the historical background of the child's ethnic group; concepts of cultural change; and modification.
