Some things roll, and some things slide! A ball rolls because it is round. It goes round and round when you push it.
A box slides. It moves straight across the floor when you push it. Boxes do not roll because they are not round.
We use rolling and sliding to make work easier. You can roll a toy car or slide a book across a table. Isn’t it fun to watch things move?
