Museum I Spy
Art books (or museum guide) or web access to the museum collections in advance
Every time we go to the art museum, we always play I Spy. We bring an art book or two (or when traveling abroad, we make color copies from books of the paintings that are housed at the museum we plan to visit) and review the paintings we're going to search for. Then, when entering a gallery, the kids are looking for something specific. When they're older, the game becomes more general - they have a copy of a Degas or Monet, and they have to find another by the same artist. Another twist for the really young ones is to play "I Spy" in a gallery -- looking for a painting by an artist, of something in particular, using certain color combinations, etc.
