That's common. They have plenty of money for "facilitators" and "consultants" at the school district HQ, but no money for paper, pens, pencils, or tissue paper, so they ask the parents to supply those. The only reason they don't make you buy the books, is that you might read them and that wouldn't do.
This thread is a goldmine.
My first thought was: "Tell her to take the tissue money out of the school condom fund.."
