What are walls?

A wall is like a big, strong friend that stands between you and something else, like your bedroom and the hallway.

Imagine you're playing with your toys in your room. The wall is like a tall, flat friend who doesn’t let your toys run out into the hallway unless you ask nicely. It’s made of bricks or wood or plaster, things that are really hard to push through.

Walls help keep your room safe and cozy. They stop the cold from coming in when it's winter, and they can even block out loud noises so you can sleep better at night.

Some walls are just there to divide spaces, like how a wall separates your kitchen from your living room. Others are really strong, like the ones around your house that keep everything inside!

Walls start as just lines on paper, but then builders use bricks, concrete, or even big pieces of wood to make them solid and tall. It's kind of like stacking blocks one on top of another, except with a lot more blocks and a lot more strength!
