This publication is an updated, edited merger of two earlier National Council on Economic Education documents: "A Framework for Teaching the Basic Concepts" and "Economics: What and When." The combined publication is designed to aid those who construct curricula or who provide economics instruction in U.S. schools. The book provides a concisely stated set of basic concepts for teaching economics below the college level and a set of guidelines to enable schools to develop a systematic program of economic studies from K-12. The seven chapters include: (1) "Introduction"; (2) "Basic Concepts"; (3) "Applying Economic Understanding to Specific Issues"; (4) "Overview: Scope and Sequence Guidelines"; (5) "Guidelines, K-4"; (6) "Guidelines, 5-8"; and (7) "Guidelines, 9-12."
