School

So, someone tell me what are all the gallon and quart baggies for in school? I mean I've seen one or two come home throughout the year but not a whole two boxes worth. What do they seriously use them for? I'm just wondering. And another thing, how can I buy my kids their stuff and not put their names on it. It saves the teacher time why can't I make sure what I paid for is what I get. I don't mind helping others in need but if I pay more for something because my child wants or needs it, shouldn't I be able to ensure my child gets theirs. Again I'll even buy extra but if I buy left handed scissors because my son is left handed then I want my son to get to use his left handed scissors. Not right handed. I mean think about it, why do we even need to buy some of these things? I bought scissors for my daughter last year for Kindergarten, but they never came home at the end of the year so what happened to them? And the folders, if I buy plastic folders it's because it's more durable and that's going to make it through the year unlike the paper ones that my children keep bringing home. Just saying!
