In this activity, students apply the concept of opportunity cost to the economic decision of going to college. They examine both the opportunity cost of going to a college of their choice, and not going to college. This worksheet takes students through a step by step process to calculate this cost. At the end, students are required to answer a short answer question detailing what choice is best for them by explaining the opportunity cost associated with each decision. My economics students find this to be a very engaging way to apply the idea of opportunity cost to their daily lives.
