Paul and Gail Dennison have this exercise in their book, Brain Gym that helps with math and spelling skills.  The elephant will also help you to listen better.  Stand up, bending your knees and 'glue' your head to your shoulder and point across the room to the left.  Use your ribs to move your whole upper body as you trace a Lazy 8 on it's side.  Look past your fingers.  Then, repeat with the other side.

If you have your child practice spelling his or her spelling words in the air, it helps him or her to remember them.
