Circle

I'm a circle
I spin round
Like a wheel across the ground
Got no corners
Got no points
Got no edges
Got no joints

Neither triangle
Nor square
You'll find my shape everywhere
On a record
On a cake
On a saucer
On a plate

I'm a sphere
When in 3D
Draw a letter O - that's me
As a counter
As a clock
As a zero
As a watch

I'm a disc
So I can roll
Like a ball that scores a goal
I'm a penny
I'm a hoop
I'm a planet
I'm a loop

I'm a circle
You can see
I have perfect symmetry
I've no bottom
I've no top
I make endings
With full stops.
