I have a container full of keys from, oh who really knows. T found them and was instantly in love. It is always the oddest things that catch their interest, isn't it? I saw an activity in our future. I stuck them on our home copier and made a copy of the keys in different positions. Then set them on the table with the key container. Sure enough, T knew just what to do. Matching the keys to their picture. He played with this game for a long time, wondering aloud, did this go to the car, did this one go to playroom door? It was a big hit. Great for matching and problem solving. I think next time I will write numbers on the keys and the pictures and turn it into a number recognition game.
