Favorite quote from this TED Talk with teacher John Hunter:

“Spontaneous compassion.”

From TED:

John Hunter puts all the problems of the world on a 4′x5′ plywood board — and lets his 4th-graders solve them. At TED2011, he explains how his World Peace Game engages schoolkids, and why the complex lessons it teaches — spontaneous, and always surprising — go further than classroom lectures can.
