Wouldn't it be nice to experiment with a gradebook and see how it is setup without having to risk messing up your own gradebook? If your answer is "that would be great, tell me more" I have the website for you. Aereies created a site for elementary and high school teachers. You can open the gradebook and experiment as much as you want to. Practice inputting grades, changing scores, and even taking attendance. http://www.aeries.com/products/online-demos After you click the link look for Aeries Portals to begin.
