My 10 year old son needed it too.
There was a kickball game going on in the school yard. Apparently one of his teammates argued about whether he was safe on base. My son stood up for his teammate saying he saw what had happened. Three kids ganged up and jumped him. My son did a front kick to the chest. They backed off immediately and the game had to end prematurely.
Unfortunately, he was cited by the school for inappropriate behavior even though it was, in his mind, done in 'self defense".
I'm not sure how he could handle it differently, but we (his instructor and I) talked about this and suggested he try other alternatives first if possible (considering this is on school property, during school hours, and there are school adults around that could be called in to help defray the confrontation).
