Use this to help keep track of missing homework.
I keep it in a binder, in numerical order. (My students all have numbers, but this could easily be done alpha by last name.) When I'm collecting homework, any student who does not have their homework is required to fill this out. On Friday, I quickly scan through the binder and e-mail home the parents of students with missing homework. This keeps everyone "in the loop" and on the same page.
Teaching English sometimes means that it takes a while to get assignments back (think grading multiple page papers for each student) and this helps me keep parents informed in a timely manner!
Great for all subject areas!
