This resource includes two rubrics for each style of writing required of 6th graders according to the common core standards (informational, persuasive/opinion, narrative). One rubric is a 1-4 scale and the other is based on a percentage grade of up to 100. Note: this rubric does allow for students to score higher than 100 if maximum points are given in each of the areas. (This would show that students are capable of more than the standard requires for 6th grade.)
