I chose the Angry Bird game. I got stuck on zombie game 12 even though I made about 20 attempts. Took a break, ate lunch, went back to it. Finally figured out in another 10 (?) attempts. However, passed 18, 19, and 20 all within one try! Apparently my brain needed fuel. Good reminder for my classes right before lunchtime.
I’ve been considering doing centers in the library. It would be interesting to test run Hour of Code as a center and assess interest level.
