I use this form to remove the disruption of student unpreparedness.
Students complete this form (which is available with a pencil to fill it out) and place it on their desk. I bring them a pencil or the notes they need and pick up the form. I leave the form in a place I can see it, so that I remember to get back my pencil before they leave the room. This saves me from having students exit the room and miss the first few minutes of class because of a locker trip.
This form is created in Microsoft Publisher. It prints 3 per page if you set the print settings to multiple copies per sheet.
