I do homework packets primarily to pass out spelling words for the week as well as an overview of what we're studying. The grade is 100% "are you capable of turning in homework?" based. Anywho, I had a mom call today to handle her daughter not turning in homework. The solution she asked for was the missing homework packets... from two months ago. Now, I'm happy enough to put together a few packets to help this girl practice turning in homework, but I did have to explain that I don't keep homework that long. I make a couple extra copies a week for backup, but after so long any remainders get tossed. How long do you keep old homework/assignments?
