Good for this school and the teachers involved! It's so great to see parents and teachers actually teaching their children to fend for themselves and learn to work together without the constant assistance of adults. So many parents teach their kids an absolute lack of personal responsibility and create helpless children who turn into helpless adults. This is a great idea, I hope it catches on to other areas.

I'm 70 plus and can still remember what we called "free play" during recess as a little kid in grade school. What fun we had scraping dirt into piles and walls to build castles and forts and playing on things like teeter-totters, merry-go-rounds, rings, and monkey bars where there were real consequences if you didn't work things out with your playmates. In those days if you got hurt, the nurse would patch you up and your folks would scold you for not being careful. And the lesson stayed with you

I'm not saying it was better in the "old days" but, I'm glad to see kids given the opportunity to make their own mistakes and discover the rules for getting along with each-other by themselves. I think developing one's own sense of the need for civility to get along in this world is too important to only be treated academically, it also needs to be developed through experience at a young age.
