My wife really shouldn't let me go to Target. Every time, she sends me to get one simple item, and every time I show up at home with a new board game. I keep telling her "It's helping the kids learn!" but honestly they'd probably learn plenty from the other 28 board games we have...
But you, dear reader, get to benefit from my game addiction! A few weeks ago, I spied a game in retro packaging that I'd never seen before. I eagerly snapped it up and brought it home.
Within minutes of playing the game, I couldn't wait to see what my own students could do with the mathematical implications of the game. It's a great game for a 3rd or 4th grader, but the mathematical ideas that the game uses are taught in high school and college courses on discrete mathematics. Not that your kid will know that! To them, they're just guessing which colors match your secret code.
