I hate using "traditional" bound teacher gradebooks! I created this gradebook sheet template and have been using it for years. Simply input your students' names, save your work, and print out enough copies for the semester.
I usually print out a copy for each class period, staple all the pages together, and use the set throughout the week to manage all my classes. Later, once the sheets are filled, I enter the data in my school's online gradebook. Next, I remove the staples and hole-punch the pages, filing them in a binder with sections for each class period. Super easy!
I hope you will find this gradebook sheet template as useful as I have over the years! I simply can't function with it.
