I suppose to supervise the children
to answer your question about the check board I have on mine each child's name that will be in for today and then I have 4 slots beside the name for parents to sign in and then the time plus later to sign out and the time of pick-up
the emergency information you keep separate on an emergency card for each child so it is not on display just for you to see when you need it. I keep my cards in a small file box handy for me if I need to call a parent etc
