I don’t know about your school district, but in my first school district, I was not allowed to ask parents for anything. That’s right. Nothing. I couldn’t even send home a “wish list”. So needless to say, nobody donated tissue boxes to my classroom and I couldn’t spare a cent of the $250 I got for my classroom as a first year teacher. So I came up with another solution to tissue boxes: a roll of toilet paper. I was able to get rolls from the custodian and he even mounted a roll holder to my wall! We made sure to get a holder that stopped itself after a few squares so my kids wouldn’t be able to TP my classroom (sigh… kids…). I know it’s not fancy, but it took care of the problem.
