I graded an assignment and then allowed the student to resubmit the same assignment for a better grade.  Both assignments are uploaded with different submission dates but the rubric for the 2nd assignment shows the points and comments for the original assignment.  I thought I would be able to use a 2nd rubric and the highest score between the two would be in the grade book.  Do I have to delete everything on the original rubric and grade the 2nd submission?  If not, how do I get a blank rubric in speed grader to use for the resubmitted assignment.

Thank you for any feedback!
