Supply and Demand graphs tend to be a struggle for many of my students. I created this quiz as a way to assess their understanding and an attempt to make supply and demand graphs more engaging. I have often used this as a group quiz which really works well. A lively discussion tends to exist within the group model as they debate whether it is a quantity demand, quantity supplied or just demand/supply issue and the reasons why. Note, I usually hand out Starbursts while they work too! How bad can a quiz be where you receive candy while you work!
