📖 Let Us Begin!
Stand up and look at yourself. You have a head, two hands, two legs, and so many other parts! Your body helps you run, play, eat, read, and do everything.
Your body also has five special helpers called sense organs. They help you see, hear, smell, taste, and feel the world around you.
Let us learn about our wonderful body and how to take care of it!
External Parts of Our Body
The parts of the body that we can see from outside are called external parts.
Head -- has our hair, forehead, eyes, ears, nose, and mouth.
Neck -- joins the head to the body and helps us turn our head.
Arms and Hands -- help us hold, write, eat, and carry things.
Legs and Feet -- help us walk, run, jump, and kick.
Chest and Stomach -- the middle part of our body.
Fingers and Toes -- we have 10 fingers and 10 toes.
Think about it: How many things can you do with your hands? Writing, eating, clapping, waving -- your hands are very busy!
The Five Sense Organs
We have five sense organs. Each one helps us understand the world in a different way.
