Yep, I was going to suggest The Homework Myth to confirm that really, no kids need homework.

In my humble opinion, homework is designed to make sure the parents know that the kid is doing something at school and to demonstrate progress to parents. DS has homework every day and it takes him 15 min to do, plus his required and documented 20 min of reading every day. We do it but I disregard a lot of the individual assignments and make them better and more fun.
