This is the powerpoint I use for my market structures unit. I created a chart that I give the students and they fill in as we discuss each market structure (the chart looks just like the chart on powerpoint slide except all the market structures are on one chart). The first part of the powerpoint discusses the characteristics of each market structure. I also have some youtube clips that discuss preston tucker and the history of his tucker torpedo (if I decide to show the movie, then I skip over this part). I also included "Prisoner's Dilemma" but you can omit this if you would like.
The next part is a review quiz (can grade or just practice) - these slides are timed...the slides show pictures of different businesses and the students have to decide which market structure that business falls under (for example...if I show fast food, then the students would write monopolistic competition on paper). I usually do the day after we finish discussing the characteristics of the market structures.
The next part of the powerpoint includes my merger/regulation notes.
you can save powerpoint and add to/take away from what I do. This is one of my all time favorite units to teach. Please let me know if you can't open powerpoint or if you have any questions.
