I just watched a seasoned first grade teacher walking her class to lunch (yes, it is only 10:45, that's when we have lunch). She had one little friend who was not staying in line and kept touching the walls. She said to him, very kindly, "I'm going to walk with you, friend, because I see that you're having trouble keeping your hands off the walls."
I have this same problem with several students regularly. I make them hold my hand (it's a terrible punishment in the eyes of one, at least). However, I've never put it so gently to them. Listening to her was such a small thing and yet gave me so much to think about. It's amazing what I learn from the other teachers around me.
