When my son was in middle school, he

did similar thing: forgetting to do homework, forgetting quiz time, etc. We bought a really nice planbook for him and work with him using the planbook for each day and week plan (like homework, quiz time, project due date). Even nothing to do, just write down nothing to do or relax time. It takes months or so for him to get better. Our feeling is that boys (or my son) will just need to be pushed from parents :).
