Puzzle time!

Mommy and Daddy are helping me learn my shapes. I know square, and circle, and triangle, and I'm working on diamond, hexagon and octagon. Hexagon is pretty hard to say, though. Mommy got me this puzzle to help me learn, and I can work it all by myself! (Mommy's note: please try not to notice that the afternoon sun is streaming in the window and that he is still wearing his pajamas. He can say "hexagon" for goodness sake. What more do you want from me?)
