Circle

(Tune: "The Wheels of the Bus")

A circle is round and round and round,

Round and round, round and round.

Like the pizza and the wheel and ball I found

Rolling around.

Oval

(Tune: "Twinkle, Twinkle, Little Star")

Oval, oval, not so round,

Like a race track on the ground.

Like a football or an egg

That a little chicken laid.

Oval, oval, not so round,

Like a race track on the ground.
