In this day and age, homework is busywork. Spend 2 hours making a macaroni MLK portrait, etc. the schools do this to focus blame elsewhere. Most kids do to school over 40 hours a week. 730 to 4 is common. Then if they are in sports or choir or debate etc, they begin a few hours of wasteful homework at 7.
If you have someone as a captive audience for 40 hours a week and cannot educate them without monopolizing the family all night, something is wrong.
Homework should be rare and important. Not propaganda, not time wastes, not art.
I’ve found with my children that homework is often used to force parents to teach the subject matter to their children (as many of the teachers themselves don’t know it). I’ve also realized that if your children aren’t in “honors classes” (which are about on the same level as “regular” classes 30 years ago) they have been completely written off - the worst teachers and the lowest expectations.
