Sing Along to the shapes song. Lyrics:. "Look out, we are shapes. |--| I am a circle. You can see me everywhere. Like a full moon in the night. And the eyes of a teddy bear. I am a square. You can see me everyday. Like the tiles on the floor. And your pizza box I say. I am a triangle. You have seen me I am sure. On the sail of a boat. And a pizza slice you know. I am a rectangle. You have seen me oh you have. On your window on your door. And even in your microwave.".
