The last of three main parts designed for fifth grade students, resource unit seven provides an overview of patterns of Latin America and a system of regionalization for the total area on the basis of population composition. Following the overview, a series of case studies arranged in separate sub-units on Buenos Aires, Manaus, Sao Paulo, Chile, and Cuzco illustrate different population compositions and other regional differences. After completing the case studies students turn to culminating procedures on Latin America as a whole and, further, generalize previously learned concepts to the entire course. The teacher's guide provides program descriptions, course objectives, teaching strategies, and an explanation of format in ED 062 226. Other related documents are ED 061 134, ED 062 227, and SO 002 732 through SO 002 741. (Several pages may be illegible.) (Author/SJM)
