One of a series of units on business issues designed for secondary school students, this packet examines United States and Soviet trade within the context of worldwide economic and political associations. Introductory in nature, the 5-day unit is suitable for use by itself or as part of a larger study of comparative economic systems, American foreign policy, or Soviet international studies. Teacher and student materials are provided in separate sections. The teacher's guide contains five detailed lesson plans, recommendations for follow-up activities, answer keys, student handouts, and background information. Following an overview of the American and Soviet trade situation, the student materials section examines trade barrier restrictions, trading patterns, and trade as a political weapon. Eight student activities include two introductory cases, one set in the Soviet Union, the other in Minnesota. The case studies illustrate the economic differences between the two countries and the impact of governments on individual businesses. Other activities include readings on trade patterns and governmental tools to control trade; map study; skill building exercises using statistical charts and graphs; and a panel discussion about the Soviet pipeline.
