Is he given a stack of work at one time? I know that is typical in my son's 2nd grade classroom - the teacher will place 5-10 worksheets on a kids desk, then go over them. Some will be required, some not, but if my son were to sit down and see 10 work sheets on his desk he would promptly FREAK OUT. So one of things she does is only give him 2 things at once. She keeps the rest on her desk. His 'extra' work goes directly into his chair pocket.
I know your child is older, but perhaps something similar could help - one assignment at a time, that is turned directly in when finished, as opposed to holding onto several things for the duration of class.
Good luck to you. It seems like the teachers want to just race to summer this time of year!
