Is this an assignment for a class? I see you are a college senior, so I suppose it is an acceptable assignment for future teachers. First, you can probably buy one at a good educational supply store. There are many different varieties with slight variables to most of them. Most roll books include blank spaces for 25+ students listed from top to bottom of the book. From left to right are small grids on double pages to allow for grades and/or other notations, such as absences, tardies, incompletes, etc. There are generally enough of these pages to document all of the classes you may be teaching (five course, six courses, etc.) These grids generally cover enough space for a school term (six weeks, nine weeks, ten weeks, etc.). At the very far right of each right page will be additional gridded spaces for such things as grade average, exam grade, final grade, total absences, etc. There is usually additional space for notes, student and/or parent information and even suggestions about keeping a good roll book. I would suggest you visit an educational book store and either buy or look over a roll book (or borrow or view one from a current teacher).
