Google (Docs) Has A Draw Program!

I needed to produce a document for an elementary school math festival I am participating and organizing on Friday in Glassell Park. I don't really know how to use any Draw programs and I am not "artistic" at all but the above diagram I literally created in 15 minutes in Google Docs. I heard about the program from my husband but you can read more about it here. You simply "Insert Drawing" and you get a wonderful graphical interface which is very intuitive to use.

Thanks, Google!
