This teacher's guide for the instruction of economic concepts at the seventh grade level uses Evansville's (Indiana) historical development to further the study of concepts such as economic needs and wants, factors of production, and opportunity cost. The first part of the guide, "Introducing Basic Economic Concepts," uses the text "Enterprise Island: A Simple Economy" and the student activity booklet "A Study of Basic Economics." The corresponding chapters from the activity booklet are reproduced for each unit. The second part of the guide focuses on Evansville, and the reading materials and student activity sheets are reproduced as student handouts. An 18-item test on economic terms and a 49-item examination on Evansville are included. (DJC)
