He's so crafty

I'm already wondering where preschool teachers come up with this stuff.
Here is his "A" week craft. A very beautifully decorated apple. Torn paper and pieces of crepe paper and he is so proud! "Grandma M would like this!" He told me right away. "It's red, and it's an apple."

And how many times was the project or idea an accident? Like this ball rolling painting. He came home and said "you might think I made this with a paintbrush or my hands or fingers, but I did it by rolling a ball." Really? Did they discover this accidentally when one child put a ball where it shouldn't be?
