Hi S.,
I had the same problem with my son when he was 5 (he is now 13, 8th grade). It's the impulsive thing, to see what kind of reaction he gets, even if it's negative. My son also had trouble staying on task, not paying attention, etc. He ended up with a diagnosis of ADHD. Not that you're son is adhd,just sharing with you what I dealt with. I would always have to tell him to keep his hands and feet to himself. Keep close contact with his teacher about his behavior and keep doing what you are doing with consequences and eventually maybe he will think about his actions before doing them. Good Luck
