Ok, I found Eco's thread but it sounds like the homework turn in issue is related to actual hard copies. Aside from math (which is the class she's doing well in so far) all of dd's homework is typed up and turned in/uploaded electronically. The online computer website/system they use lists homework on a calendar and when you click on each subject's 'homepage' it will list upcoming assignments. There is also a grade page for each class showing what has been entered for a grade but sometimes it will show a zero for an assignment because the teacher hasn't entered it yet.
Even I'm overwhelmed at keeping track of what has been done (at home) and what still needs to be done because there are so many different pages to go through to find what you need.... from notes, to study guides, text, power point presentations, etc... Not to mention sometimes teachers will list an assignment on the weekly agenda page but that assignment won't be on the calendar assignment page.
So the ideas in Eco's thread won't help us much.
