I many times have parents ask if there is anything that they can donate as a way of helping supply needed materials for the classroom.  Following is a list of items that I use throughout the year:

stickers

12 oz. cans of caffeine - free beverages (lemonade, Hawaiian punch, root beer)

extra tissue boxes

Bounty or Brawny paper towels

golf pencils

Ziploc bags of various sizes

small pieces of candy
