This lesson plan offers students the opportunity to participate in the three basic economic systems (market, command, and tradition). By working in each of the systems, students will internalize the fundamental values present in each system and will gain insights into the basic advantages and disadvantages of each system. The lesson plan provides objectives; lists materials needed; and outlines a step-by-step procedure. Attached are information sheets about the economic systems, scoreboard sheets, and answers. (BT)
