This fifth grade resource unit on regional studies is part of an articulated curriculum for grades K-12 that emphasizes sequential development of attitudes and skills, as well as generalizations and concepts. An inquiry teaching strategy encouraging children to find out things for themselves is presented. Children are asked to make guesses or set up hypotheses regarding regional situations by drawing upon previously-learned concepts and generalizations. The main theme of the course is that man uses his physical environment in terms of his cultural perceptions, values, and level of technology. The unit centers on selected sequent occupance case studies showing how man has dealt with his environment over time. The pupils focus upon a few case studies rather than a detailed study of each region. This course includes three main units, arranged geographically, that present an overview of the patterns of the country and a system of regionalization for the United States, Canada, and Latin America. The main part of each resource unit is set up in a double-page format to help teachers see the relationships among objectives, content, teaching procedures, and materials of instruction.
