A nice lesson that covers the economic problem. The lesson looks at scarcity and choice and how resources are allocated. The lesson looks at opportunity cost and includes a nice task on this topic. I have also included a Mars Bar utility task which will keep students engaged. I have also included a keyword scramble and a nice factors of production gap fill task. I have also included a nice worksheet based on topics around the economic problem - this worksheet includes matching tasks, gap fills and questions. I have also included a student version of the lesson. This lesson can be used for Economics.
