3Step by step Steps

1. Step 1: Know the parts of our bodyOur body has four main parts: the head, the neck, the trunk and the limbs. On the head are the eyes, ears, nose and mouth; inside the trunk are important organs like the heart, lungs and stomach; the limbs are two arms and two legs, which let us write, carry things, walk and run. Each part has its own job, and together they work like a helpful team. Learning the names and positions of body parts is the first step in protecting them: when we know how important they are, we take care not to hurt them.
2. Step 2: Eyes — the windows for seeingOur eyes let us see colours, pictures, words and the people around us; they are our greatest helper for learning. Read with enough light and keep the book about thirty centimetres from your eyes. After about thirty minutes of TV or tablet time, rest the eyes by looking at distant trees or the sky. Never rub your eyes with dirty hands, and be very careful with sharp things like scissors and pencils. Eye injuries are hard to fix, so protect your eyes every single day.
3. Step 3: Teeth — helpers that chew our foodTeeth chew our food: the front teeth cut it and the back teeth grind it, so it is easy to digest after swallowing. At about age six, baby teeth become loose and fall out, and strong new permanent teeth grow in. A permanent tooth that decays or is lost will never grow back, so brush every morning and night, rinse after meals, eat fewer sticky sweets, and never eat again after brushing before bed. Healthy teeth make food taste better and smiles brighter.
4. Step 4: The spine — the pillar that holds us upThe spine runs down the middle of the back. It is made of small bones joined together, like a straight pillar that holds up the head and the whole body and protects the nerves inside. Because of the spine we can stand tall, bend to pick things up and turn around. If we always slouch, the spine slowly changes shape and our backs may ache when we grow up. So sit with a straight back against the chair, stand with the head up, chest out and shoulders level, and keep the spine in a natural straight line.
5. Step 5: Sit and stand the right wayGood sitting posture means: back straight, sitting on the whole chair, both feet flat on the floor, chest about one fist from the desk, and eyes about thirty centimetres from the book — never lie on the desk to write. Good standing posture means: body upright, head up and chest out, shoulders relaxed, feet a little apart — do not lean sideways against the wall. With good posture the spine grows well and we look lively; it also helps us focus in class and do homework well, and Mum and Dad will praise us for sitting so nicely.
6. Step 6: Protect our body every dayProtecting the body is more than good posture. Do not rub the eyes with dirty hands; read in good light. Brush teeth morning and night and eat fewer sweets. Trim the nails, wash the hands and keep the body clean. Wear a seat belt in cars and warm up before exercise to avoid bumps and falls. When parents tell us to sit up or not to read lying down, they are caring for our body. Remember these rules and do them daily, and every part of the body stays healthy as we grow up happily.
