These are two great resources to easily create a rubric for your Common Core assignments/projects:
A rubric is a criterion referenced assessment tool used to score assignments or performances. Work is scored/graded based on how well the finished product lines up with the criteria listed on the rubric. A rubric is a very powerful device for performance-based assessments, such as oral presentations or projects, but also makes grading essay questions and narratives quick and easy.
