For the letter C week, I made 10 colored cats out of felt. I was going to add googly eyes but decided against it.
I got the template here.
The idea is to practice colors and counting with something that interests him.
I also reorganized the playroom a little bit to make an area for the felt board and felt pieces, so it is all more accessible to him. This week, in the one drawer are the cats, in one drawer is Noah's Ark, and in another you have the Cars pieces.
