This worksheet goes along with an in class simulation to show students how different scenarios affect supply, demand, and price. You divide the class into two groups, buyers and sellers. You then establish what it costs to make a candy bar. The sellers are encouraged to sell below this. You give monopoly money to the buyers and simply tell them to get the biggest bang for their buck. They go around trading according to each scenario. For example, during the depression, take away most of the monopoly money. For the introduction of a substitute good, have another student start selling jolly ranchers at low prices.
After each round, identify vocabulary, describe the changes in the market, and illustrate this change with curves.
My students LOVED the game, and it helped them practice shifting their curves.
