This is an interactive SMART Notebook Activity that is a fun exercise which relates changes in supply and demand to the market for Hershey Bars. There are twelve pictures which need to be sorted into each of the four possible market changes (increase or decrease in demand, increase or decrease in supply). There are three pictures for each category although some have more than one interpretation, meaning discussion is often required. It works best with one student at the front controlling the board, with the rest of the class advising / discussing the interpretation of the picture and which category to place it into.
