That is just the attitude that I saw many times and I taught on the outskirts of Atlanta also. I did grade homework, but did not count it as much as classwork, because the parents often did the work. That's alright if the student is there learning, but the student should not be given as much credit when he has not done the work. The real test is if the student can do the work in class with little help. Only when parents and teachers are working together for the benefit of the student is there real progress.
