Ok I have a silly question but I am completely lost on the answer and figure here would be a comfortable place for me to ask without getting too much flack. These are the types of things they need to teach in college... Last year was my first year of teaching and when I bought a gradebook I noticed that to the right of where I wrote the students names was perforated to separate the names from the grades. I thought it was just this one book and was annoyed by it because throughout the year they kept falling off. So when I went this summer to buy my gradebook for this coming year I noticed they all have that. Why is that? I teach ELD, Reading, and my homeroom class so I need to have different names on the pages depending on the class. Someone solve this mystery for me. why the perforations?
