I've created several printable music games recently. I like the challenge of planning an interesting game, and then designing the graphics so it has strong appeal to kids.
Chomp! Music Theory Game is a game that helps music students drill simple rhythms and time signatures.
You can learn a little more about the game at the following link, or browse the rest of this post to check out the graphics that I designed for the game.
Here's a screen shot of the game board. It can be printed on two pieces of 8.5 x 11 paper and taped together.
Here are the images I designed for the foldable game pieces.
