Marking Element Unit work

I have been busy marking all the element of art work our classes have been doing and a little pet peeve is emerging!  First I have started a no name bin which is holding about 50-70 papers that have no name.  Secondly students that have taken homework home but don't bring it back.  My homework rule is Take it home, Do it, Bring it back.  If any go these 3 steps are not done I can't mark it.  So students are receiving an ED on their Element work until their homework is returned, then their work will be marked.  If it is not turn in before Term 1 mark cutoff the ED stays.
