Marble painting is great way to work on fine motor skills. You don't need many supplies and it's not too messy.
Take a cookie tray or cardboard box and put a piece of paper on the bottom.
I added a couple of marbles. You can use any number you want.
I added a few drops of paint.
I then had the kids tilt and move the tray so the marbles rolled the paint around.
Once it was dry, I had them cut it out in an oval shape for an egg. If your student can't cut, you can cut the shape out before putting the paper on the bottom of the tray.
