Getty Games is a nice collection of art-based games produced by The Getty Museum for younger students to enjoy. There are four categories of games, each offering a subset of games. Getty Games also offers directions for a selection of offline activities.
The four game categories offered by Getty Games are Detail Detective, Match Madness, Switch, and Jigsaw Puzzles. In Detail Detective players are shown four small pictures and have to identify which of those four came from the larger piece of art shown to them. Match Madness offers four games in which players match either match two parts of a picture together or match exact images. In Switch players are shown two pieces of art side-by-side and have to identify the parts that have been switched or altered. There are twelve jigsaw puzzles available on Getty Games. The neat thing about them is that players are shown the completed artwork and then choose how many pieces they want to have to put together to reassemble the artwork.
Applications for Education
After spending some time exploring art online at The Getty Getty Games could put the art into a "fun" context for students. The games might be a fun way for students to be reminded of some of the art lessons you've previous taught.
