Holy cow! That seems like a lot.
last year my son was in a private school for K, and they didn't have homework at all.
This year, son is in public first, and he is supposed to read for 20 minutes every night. He also gets a list of sight words and spelling words each week. He doesn't have any specific homework associated with that, but he has to know them by the end of the week. The teacher sent home a list of suggested activities for those words at the beginning of the year, and said we should do whatever of the suggested activities we feel would best help our child learn the words. And 2 or 3 times a week he gets a one page math worksheet.
So far, other than reading, I can't think of a night that we've spent more than 10 minutes on homework, and many nights we haven't done anything at all.
