I'm Four, have you met me before?

I’m One more than Three, that’s plain to see.

Three plus one equals me, I’m Four!

I can be thin and tall, I can be low and long, I can be shaped like the letter L.

But the best shape of all, is stout and strong.

What shape is this? Can you tell?

I like to be square. I like to see square things everywhere.

Anywhere there's a square, you'll find me right there.

Square cheese on square bread, square quilt on a square bed.

Square is where it's at, of that you can be sure.

Anywhere there's a square, you'll find more.
