A lot depends upon what grade they teach. I taught elementary, middle and high school and the needs are different. If you're talking elementary a couple of things came to mind for me. I used to get a box of pencils from Office Depot for about $5.00 for kids who always lost pencils. I little bag with a zipper or velcro would be good for that.Teachers never get to leave for lunch. A fabric bag, maybe draw string, would be great to carry lunches in and then thrown into the fridge at work. I used to use plastic grocery bags!
