Playdoh Economics (2)

In my previous post on Playdoh Economics, I shared how I use playdoh to get the students engaged in the basic concepts of Economics, many of which they have already done before. I also use the Playdoh for graph revision, and a couple of the students efforts are shown below.

Having picked up two new classes after a long summer break, I thought it would be a good idea to review the basic competition graphs, so gave them a choice of “creating” monopoly or perfect competition, and supernormal or subnormal profit. They enjoyed working with the playdoh and I was able to go around and remind them of a few important points, such as MC cutting AC curve at its lowest point.
