Developed as part of a 37.5-hour microeconomics course, this lesson plan focuses on the concepts of supply and demand analysis used to determine market equilibrium. The objectives of the 50-minute lesson are to enable the student to: (1) explain how a demand schedule is derived from raw data; (2) graph a demand curve from the demand schedule; (3) state the Law of Demand; (4) explain the three determinants of demand; (5) explain how a supply schedule is derived from raw data; (6) graph a supply curve from the supply schedule; (7) state the Law of Supply; (8) explain the three determinants of supply; and (9) combine the demand and supply curves to determine equlibrium. The lesson plan begins with information on the course for which the plan was developed; equipment and audio-visual aids needed; requirements for student materials; course objectives; bibliographic references; and special remarks for the instructor. Next, a step-by-step outline of the instructor's presentation is provided in a format indicating the length of time and the equipment or other aids needed for each step of the lesson. Course handouts and transparency masters are included. (EJV)
