As noted in the post on Classroom Expectations, some work is not graded.

This is not because it is unimportant work. It is because logistically it is not possible and it is not necessary. Things like taking notes from the reading or completing the key terms are important because they will help you learn the information and study for the exams. Also, I give reading quizzes to grade your reading/notetaking. I give exams to grade your overall knowledge. I give notebook quizzes to check for completion of assignments and homework.

So, even though I may not grade it, does not mean it is not important.
