Identifying spheres
Look at this bouncy ball. What shape is it?
This shape has a special name. It is a sphere.
A sphere is round all over, like a perfect ball.
It has no flat sides anywhere.
And no corners or pointy parts.
That means a sphere can roll any way you push it!
An orange is a sphere too. Round all over.
A tiny marble is also a sphere. Big or small, still a sphere.
If it's round all over, with no flat sides and no corners, it's a sphere!
