Usage: Teaching your baby some basic colors is a great activity for more advanced signers. Start with a few simple flash cards of the basic colors. A great thing about this game is you can play it anywhere when you have a few minutes. Point at the grass, or a plant, and do the sign for green.
Teach the colors through the flash cards. The primary colors are a really great place to start, so you may want to also add yellow, blue, and red.
