I've approached this in two ways. I started to focus on one color every week or so and I pull toys from our stash that are that color and set them aside (he doesn't see them unless we're doing this activity). I try to pull them out everyday for him to play with. He's not one for sorting or really investigating. He just wants to DO something with them. So I came up with having him drop them in the hole in the bottom of a diaper box and also use the slot in a toy mailbox we have. He loves trying to see if the pieces fit. As he's dropping them in, I say things like, "You have the red block. You're dropping the red block into the box." And as I say the color, I sign it. The awesome thing is that if you don't know sign language you can just google the word you're looking for and find out what the sign is, just like that!
Prism bricks on the light table. If I give him the whole set he tends to just throw them around (I think this is his way of telling me he's overwhelmed). So I've just been giving him the 2 x 2 bricks. He loves to stack them up over and over again. He also just puts them all one by one on the board that comes in the Prism brick set. As he stacks each brick, I sign and tell him the color.
What do you do to introduce color to your little ones? :-)
