How I move
When I was a baby, I couldn’t walk. I couldn’t pick up anything. As I
grew, I learned to make my hands and arms and feet and legs work for me.
Now I use my legs for many jobs. I use them to walk, skip, jump, run,
stoop, and climb. My legs can bend because they have joints, places that
move like the hinges on a door. If my legs had no knee joints, I
wouldn’t be able to move well. As a game, I keep my legs stiff and try
to sit down and stand up.
My arms have joints, too. I use my arms to carry, push, pull, lift,
throw, and do many other jobs. But if I hold my arms out straight and
pretend that I have no elbow joints, I can’t even feed myself.
