This 39 slide power point includes all the information you need to teach supply and demand. There are several graphs included which show the movement of the demand and supply curve and the supply curve due to the determinants of supply and demand. The power point also covers demand vs. quantity demanded, supply vs. quantity supplied, demand and supply schedules, equilibrium, shortages, and surpluses.
