I have no problem with a limited amount of homework.

1) It teaches kids executive function, as they have a selection of tasks that they have to organize and tackle.

2) It gives parents an opportunity to catch and correct things the teacher is getting wrong. So far this year, my DD was told the prime meridian goes all the way around the globe, and that condensation is when a liquid changes into a gas.

3) It gives parents an opportunity to be a different voice and present information in a different way when the kid didn't quite understand it from the teacher. For instance, we once helped DD discard the Dog's Breakfast Method (if it's not the formal name, it should be) of division and showed her how to do long division.

In our household, we DO take issue with homework that has no value and/or takes up extraordinary amounts of time.
