This teaching guide for grade 4 is designed for the study of any state in the United States and investigates how people from different cultures interact in a particular environment. The objectives of the curriculum (grades 1-8) of which this guide is a part, 11 key concepts developed throughout it, and 19 behavioral objectives, with rationales, to be achieved during the fourth grade are listed. This year's program is made up of three units, each developed around a main idea: (1) "The culture of different peoples influences the manner in which they use the same environment." (2) "Man's way of living is affected by the physical and social environment in which he lives." (3) "As societies grow, both their requirements and their problems change." For each unit, learning objectives, suggested learning activities, notes for the teacher, and evaluation exercises are provided. Teaching strategies for cognitive skills and for attitudes, feelings, and values are also included. (LH)
