Like many teachers, I have a hard time finding a grade book that I like. I started with a template from Microsoft Excel, and have adjusted it several times to arrive at this. It is fully editable. Has enough room for 34 students, and when printed front and back, it can hold 50 assignments. The columns are broken up into groups of 5, one for each day of the week. I also use this for attendance to mark P or A. The boxes are large enough to write in, but small enough to fit plenty of students and assignments.
