Interactive notebooks can be tough to grade. Be the queen or king of efficiency with this simple way to grade notebooks. Stamp completed student work and have students fill out the notebook points sheet. Students put a "Y" if their page is stamped and they record the points. Students add up their points and put their point total in the bottom right corner. Collect these sheets and enter grades.
In the grade book, I note which pages the grade is for. For example, "Notebook Points for p. 33-36." When a student is missing a page, I put which page is missing under "notes" in my grade book. This requires honesty and trust, qualities we are working to develop.
