I actually stumbled upon this 6 years ago when I was visiting an elementary school and they asked me to teach a special needs class. They said the students in that class liked to play with blocks.

I went down to the toy store and found a Jenga set staring at me. I bought that and some foam letters. The first idea was to draw foam letters and have the students draw that block out of the Jenga tower. (I wrote the letters on the end of the blocks so you can see them.) It was a big success in the class and I've just been adding and adapting ever since.
