This document will be converted to a rubric to use for grading. Items will be checked for presence,
completion, and accuracy. Overall grade will include a “neatness” aspect (please note – neatness is
not the same as “artistic” or “nice handwriting”. Neatness refers more to layout, organization, ease
of use, etc.) Final product will be worth 400 total points.
