Hi everyone! So it is more than a month into school and both of my classes continue to have trouble lining up. I ask all of them to put their hands behind their back, but then some of them walk slow which backs up the line when we are trying to leave. This is especially worse when we are lining up for dismissal. I call them up one by one, but they still manage to get out of line and talk! UGH!! Does anyone have any ideas??
