This unit on economic decision-making is the third of five units in a ninth grade social studies course (see SO 010 891 for course description). Major objectives are to help students analyze alternative choices in consumer decision situations and defend the selections; evaluate information and make decisions about what to produce, how to produce, and for whom to produce when making a product to sell; and analyze the interrelationships of producers, consumers, and government, in national and international economic situations. The unit is divided into three parts. The first part deals with the individual as a consumer, and is designed to make students more effective consumers in an ever changing and complex economic system. The second part looks at the individual as a producer, and is designed to make students cognizant of their dual consumer/producer role. The last part considers the individual as a citizen, and is designed to create an awareness that students are not living in a vacuum, but are affected by national and international events. The three parts contain lessons which are inquiry-oriented and are based on student activities. Each lesson contains a stated purpose, a classroom procedure, suggested materials, and activities. Resource pages for activities are included. (Author/JK)
