Well, this might not go in the direction you want, but! As a kid I liked kindergarten well enough, but in starting in 1st grade I got bored and impatient. Especially with homework. I saw no constructive reason to even attempt completing it.
Of course my slacker ways got back to my parents. After that there was strict oversight, but I hated it and everyone resented the process. Sometime in the 2nd grade my mom sat me down, and told me a basic truth about the society. She explained that I had to play along just enough to get along. Once the minimum obligation was observed, I could do my own thing.
She told me it was her job to make sure I actually went to school, but learning was my responsibility. I could choose to do homework, or not. So I didn't. Through 8th grade I did very little homework, and my parents accepted my C grades. Once I hit highschool I had to start doing about half the assigned homework in order to keep up. By Junior year I did all my homework. I graduated high school with an IB diploma and a high score on the SAT's. Got a large scholarship to attend an old name college. Got my commission. Am successful. Still find situations where the basic effort is all that's required. Thanks mom.
TL;DR: Homework really isn't worth fighting about, assuming your kid isn't struggling to learn.
