One of twelve instructional units in the Native American Career Education (NACE) program, this unit is intended to help Indian junior high school students understand the economic structure of their own community, similarities and differences between it and the economies of traditional Indian communities, and the implications of adding a new industry to the economy of a community through a simulation exercise. The unit includes four activities focusing on the subject areas of economics, history, and government. Each activity includes objectives, student materials, and suggestions to the teacher on how to use them. Exercises for students consist of readings, questions to answer, games, simulations, project instructions, and other learning activities. Each activity is followed by suggestions for ways of extending learning and, where appropriate, additional resources are described. Student materials may be used as master copies for reproduction or as models for material development. A test designed to measure student mastery of the main objectives is included with each unit, along with an answer key. (A guide for the whole twelve-unit program is also available--CE 014 035.) (TA)
