Sandpaper Letters, extensions

We are still using our sandpaper letters, but to keep it interesting we are adding some extensions. As a busy Mom of 3 and teacher of 40, it's easiest for me to post pictures. The chalkboard is left over from a Handwriting Without Tears Training, she uses a small cut sponge to make the M disappear. Sandpaper Letter (or Number) rubbing is a common extension on this material. I simply peeled the paper off of a crayon and let her rub it over the letter. Later, we brainstormed words with the M sound. Please feel free to ask any questions, as sharing is what this is all about :)

We do Handwriting without Tears and it ties in nicely with Montessori sandpaper letters.
Thanks for sharing your extensions. Will have to have Little Bro try yours.
