The art auction game! This is a fun game based to some degree on the concept of the Wits and Wagers Game. (This probably works best for a small group—5-12 people perhaps.) The teacher looks up the prices of auctioned works on an art auction website and shows the students the work ( I have included a few American and French artists listed on the site.) The teacher then tells the students a little bit about the artist, as well as some painting details. The teacher will then tell the students the low asking price for the auctioned work and then asks the students to guess what the painting actually sold for. To get a better idea of how to score the game look up the rules for Wits and Wagers.
I use the art auction website http://www.askart.com/AskART/index.aspx
because they list the low asking price and the amount that the work sold for. The drawback with this site is that one has to pay for it --$13 for a one day use.
Adults love this game because it's fun, entertaining and informative!
