This was used in my classroom as the sign for things I needed in the classroom. Some years I had created a "Giving Tree" or something similar. The idea was that I put this sign, with a list of all the props I needed for the class on the outside of my classroom. I included things like:
Paper towels, Cheerios, Dry Erase Markers, Kleenex, etc. Then the parents could voluntarily pick one of those items on the list and bring them to the class the next day.
