My wife and I have heard some horror stories about the increasing amounts of homework as kids move through our charter school (K-8).
My 2nd grader has 1 sheet of homework Mon. through Thur. She usually just does it all on Monday night. She also has a spelling list to memorize and is suppose to read 15 minutes. She's too smart for her own damned good, I think she actually enjoys doing it.
I guess I'm not a big fan of lots of homework, but I'd rather the kid be doing that than playing on the PS3.
