This five-lesson unit is designed to give students a flavor of what the study of economics is about, to strengthen mathematical concepts the students already know, to allow them to experience the interrelationship between the two fields of mathematics and economics and to experience success and enjoyment. Topics of instruction include: (1) types of graphs used in economics and examples of their use; (2) relationships between tabular and graphic presentations; (3) the importance of slope in linear and non-linear situations; (4) tangent as slope; (5) supply and demand laws and the point of equilibrium; (6) the importance of labeling a graph; (7) the equation form of supply and demand; and (8) gross national product in current and constant dollars and the percent of change. The pattern suggested for covering topics includes reviewing a basic graph pattern, working through a problem from a typical mathematics book, demonstrating an application of the principle in the field of economics and an assignment from the field of economics.
