How much homework for a child is too much? My grand daughter spends at least four hours on

30. The guideline is generally 30 mins per grade, max.

So a sixth grader should have no more than three hours of homework. I think that's still excessive considering how long kids are in class, but that's the widely accepted upper limit.

Personally in sixth grade we generally had a math assignment every day that we had to do at home unless we finished it in class. I certainly never did, I was and am terrible at math. Sometimes we'd also have a paper or some special project (science project, history presentation, holiday play script, etc) we were working on in the longer term, but that was generally it. This was in an advanced program, fwiw. I think an excess of busy work is a sign that a teacher doesn't know what the hell they're doing and mistakes quantity for quality in challenging students.
