Look at yourself in a mirror. You have a head, two arms, two legs, and a body in the middle called the trunk. Your head sits on top. Your arms help you hold things. Your legs help you walk, run, and jump.
Your face is on the front of your head. On your face you have two eyes, one nose, one mouth, and two ears on the sides. Eyes see, nose smells, mouth eats and talks, ears hear.
Example: When you kick a ball, you use your leg. When you wave hello, you use your arm. Now touch your nose, then your ears, then smile with your mouth!
