Terrific Teaching Tools offers many magnetic teaching aids, including magnetic numbers, letters, accents, and more. Our Clingy Thingies stick on wood, glass, walls, boards, and more, and they are reusable and dry-erase (a favorite of bus drivers). You can also use a Sharpie oil marker, which can be removed with rubbing alcohol. Find the best for your classroom and homeschool at Terrific Teaching Tools. We are your teacher's supply store.
