Miles and I have started playing a new game. We got the printables here (a fantastic blog too). I printed out the alphabet, and cut out some shapes for him.
He loves this game. We play one letter at a time, and he loves figuring out which shapes to use. I'll tell him the name of the letter and the sound it makes before he starts and he'll frequently ask the name of the letter after he's done too. He's pretty quick with it too.
