Copy the individual parts of the rubric for each trait on a half sheet of cardstock. Create a cover that is the same size. Then laminate and cut apart.
Hole punch the upper left corner of each card.
Put each complete set of rubrics on a key ring or tie them together with yarn. If you create enough so that each student has a set, the students can use these as class response cards. The students can also use them as reminders of what each rating means or as suggestions for improve their writing for each trait. I already have the work done.
