If you are looking to use rubics, Rubistar is a great resource. It is easy to use and has a ton of pre-made rubrics which can be customized. If Rubistar doesn’t work for you, check out iRubric. Both of these sites give you plenty of examples and allow you to customize your own rubrics. Both of these resources are free for individual teachers. Both can be extended to be used on-line instead of just as paper copies (there may be a cost for that though).
