Today is "Square Root Day" because the date, written is numbers, is 3-3-09. The next one won't be until April 4, 2016 (4-4-16). In honor of the day, I set A. to making a game about square roots that would help explain the idea to P, TM, and D. Here a picture of them playing A.'s game:
You can't really see the games, but one is a matching game and one is more of a board game.
Now, off to work on the square root of 9 things on my 'to do' list, especially since the conference I'm presenting at is this weekend.
