Use this marvelous math journal rubric to assess students' mastery of math concepts. Students know exactly what is expected of them when they respond to math prompts with this rubric. Simply print and copy. Two rubrics are available: one with clip art and one without. The clip art is a fun colorful dot style which if printed in black and white would coordinate with any design scheme.
In my classroom, I used a poster maker to make a large copy of this rubric for display, and it helps the students tremendously!
