The document is the third in a series of four competency-based inservice teacher education modules in consumer education. The main objective of the program is to assist curriculum developers and elementary and secondary classroom teaches as they plan, develop, implement, and evaluate a multidisciplinary consumer education program. The present module provides exercises to help teachers integrate consumer education concepts and generalizations into social studies, home economics, mathematics, science, language arts, and business education. The module also presents pretest exercises to assess knowledge about applications of consumer economics, and explains why consumer economics is a good topic for an interdisciplinary course. Activities involve the teachers in filling in short-answer blanks, taking multiple-choice quizzes, classifying generalizations, drawing up budgets, selecting credit plans, balancing a checkbook, and identifying consumer education objectives. Upon completion of the exercises in this module, teachers should be able to select appropriate content; carry out instruction in consumer education for a particular grade level or academic discipline; and relate content of a discipline to particular consumer education topics.
