This is a great way to grade your students' opinion writings. This is an opinion writing rubric that can be used for 1st-8th grades. This rubric has 9 categories (Punctuation, Complete Sentences, Spelling, Follow Writing Format, Neatness, etc.) and each category has a potential of receiving a 4 (Excellent), 3 (Good), 2 (Okay), and 1 (Could do better). Thus, each writing is worth 45 points.
