I have a one boy/one girl out of the room at a time policy. To prevent kids interupting instruction, I have a "move your car and go" policy. Each of my kids has a magnetized car labeled with their name. When they need to leave the room (bathroom, nurse,library) they move their car to the appropriate metal shape. That way I can see from across the room who is out. Also if a fire drill is called when someone is out of the room I know if I am missing someone without stopping to count.
