Little discoveries

Several weeks ago I walked into the toy room and noticed the girls had taped some of their art onto the wall.

I thought this was really neat of them to do. The art quickly became part of the wall decor, and I would walk past it without looking at it and realizing it was there anymore.

But yesterday morning I happened to walk into the toy room, and I noticed the art again. I figured it had been on the wall long enough, and I started to take it off. That's when I learned the reason behind the strategic placement of the pictures.

Hidden beneath their masterpieces was a math problem and a stick figure person. I'll give them this:  they are clever!
