Rather than "back to school" like everyone else, we've launched into a serious Settlers of Catan mode around here.
It does teach reasoning, communication skills and logic, math, and sociology, to name a few of its educational benefits. And at our house (according to Zac) there is also bribery involved.
Apparently it's not out & out banned in the rule book, so our "house rules" allow for it. Or at least it's permitted at the moment.
The simple, yet competitive (and Long) game involves collecting, trading, and bartering with bricks, sheep, wood, making settlements and roads. It's a good game. I hope they enjoy it while it lasts!
