T.N.
I'm a member of www.FLYlady.com, which really helps me keep my house clean and keep routines and have a healthy attitude towards it all. It's geared towards adults getting their homes and lives in order, but she provides a "control journal" for children to keep track of their homework, chores, etc, on their own without their parents nagging, which might really help. Kids (and husbands!) automatically resist us when we're telling them what to do, even if it's for their own good. The student control journal helps them stay organized and establish routines. Here's the link to the control journal: http://www.flylady.net/images/student_CJ.pdf
Also check out her homepage flylady.net Her systems might really help you find peace in your own life like it did for me.
