This is a one page excel file that I use as my grade book. I type in the students' names (I prefer first then last, but you can reverse it if you like). I use this as my attendance, grade book, data checklist, textbook or novel # list-- anything you need to record really.
For my grades, I put a code and date along the top. For example 10/2-HW (HW- homework, QZ-quiz, ASMT- assessment, CW-classwork), Along the bottom I write a name for the assignment.
