Guidelines are provided for integrating the teaching of the American free enterprise system into required high school social studies courses, as specified in Texas school accreditation standards. Five sample instructional units are included: an introductory unit which defines the essentials and benefits of the free enterprise system, and four units which present concepts and activities relevant to American history, world history studies, world geography studies, and American government. The American history unit is designed to promote understanding of price and production of goods and services and of supply and demand. The world history unit focuses on the evolution of economic systems including the New Stone Age, the Middle Ages, and early modern times. The world geography unit emphasizes problems faced by societies in allocating relatively scarce resources. In the American government unit, students learn how government plays a limited but necessary role in the American free enterprise system. All units contain charts of student objectives, related classroom activities and resources, and bibliographies of state-adopted textbooks and other reading materials. (AV)
