Trivia Crack

It started innocently enough.  An invitation via Facebook to play a game of Trivia Crack.  Now, several weeks later, I'm playing way more than any adult should be playing a game-especially a senior citizen.  It got me to thinking about a possible game that might be played in a classroom setting.  I came up with two games I thought might be fun.  Of course I couldn't use crack in the title-but between us-it was the inspiration for the two I'm showing here.
If you haven't played Trivia Crack, it's a simple and free download from the app store.  If you find you run out of opponents, look for me.  I'm always up for a game!
