re: The biggest problem in schools that no one is talking about

As a former Box Top collection coordinator for my daughter's school, I'm pretty sure those bonus points they're talking about on that link are Box Top bonus points (= cash), not points for grades. See the way they tally the total at the bottom? That would go towards helping a class win the popcorn party for having the most points.

ETA: this is not to say that your nephew's school or teacher isn't offering points towards a grade for stupid fund raisers, just that Box Tops has all sorts of "bonus point" themselves that they offer for different things. I know my kids' schools at least would not allow grade points for this kind of thing.
