Keep in mind, this rubric is used by the students to grade themselves and each other. We became alarmed when math work started coming home with I's and F's on them. We went to the school and that is when were told about the rubric and the scoring system. We were also advised that most of the IMP does not have right or wrong answers. Students use the guess and check method, they estimate what the answer might be.
