When I was a kid I remember building huge guns out of legos. Me and my friends would fake shoot each other with them – That was kindergarten. I remember in the third grade drawing pictures of war. Not real war but fake cartoon wars that me and my friends would draw and compare with one another – this actually got us into art and comic books, which led to reading (as I was not interested in books at that age). If I had done any of that today, I would be suspended or expelled. This article brings up a a great point – zero tolerance policies do not make sense in many cases. Boys play fake ‘war’ by nature. They need to burn that energy they have in class and on the playground.
Also here is a good video that I have posted before but if you have not seen it I would highly recommend. It was done by Ali Carr-Chellman from PSU for a TED talk
