Sorry, I think I'm on the teacher's side here. If the "homework" assignment is to bring something to read for the first 5 minutes of the day, and your son doesn't do that, the teacher has the right to give him a zero. Between now and when your son applies for colleges, he's going to be expected to do things that aren't challenging or that he doesn't like. Colleges aren't going to care. As a freshman in high school, my son failed to do what he perceived as "pointless" homework assignments. Although he is smart and mastered the material, missing homework assignments impacted his grades and he wasn't admitted into at least one school because of it. I wish he'd learned his lesson in 7th grade. On this one, it's probably in your son's best interest to back the teacher, not your son. Perhaps your son can trade books with one of his classmates.
