This kinesthetic technique is helpful for students having trouble remembering how to write letters, words, short facts, etc. It is a replacement technique for the writing in sand, Jell-O, sugar, shaving cream, etc. that I was taught in college methods classes. I was trying to re-enforce or teach. Buy the coarsest sand paper you can find. Students put a piece of typing or newsprint paper over the sandpaper.
Students use a fresh piece of paper for each item studied.
Some students are uncomfortable writing with their eyes actually closed so you might suggest they simply turn their eyes away. The idea here is to force the child to remember the kinesthetic feel of the item studied. Tell students they are practicing and it s OK to open their eyes to check their own work. They will be checked by you later for mastery. You can send sandpaper home for practice.
