Some nights homework is a monumental struggle. there is wailing, rending of garments and even hiding. Usually its just outright procrastination. With Max and Rebecca there is the added distraction of wrestling and he associated litany of complaints that begin with the time honored phrase "Mom! he/she started it."
Of course the only response to that is you may not have started it, but you can certainly end it.
I'm so helpful that way.
But once in a while all four settle down and just do the work.
