A skateboard is a piece of wood with wheels underneath. You stand on the skateboard and push with one foot to make it go forwards, or just stand on it if you are on a slope.

A sled, sledge or sleigh is a vehicle that moves along by sliding. Sleds usually have thin runners underneath instead of wheels. Sleds work best on ice or snow. Sleds are usually pulled along by an animal like a horse or husky, but you can also slide in a sled by yourself if you are going down a slope. People often call a sled pulled by horses or deer a sleigh, a sled pulled by dogs a sled and a sled you slide yourself a toboggan.
