In Kathy Schrock's recent blog, she posted links to many resources of rubrics that have already been developed that are aligned with the common core. Hope these resources will be helpful for you!
For PC users:
Rachael Boucher at MES found a great PC PDF creator called Nitro Reader. You can download it free and then there is an icon on your desktop that you drag the word file onto and it instantly creates a PDF. http://www.nitroreader.com/
One of my favorite websites in Khan Academy! I first used it last year when my daughter in high school was taking a Geometry class and needed help with angles. I was a little rusty on how to calculate transverse angles so I went to Khan Academy and within 5 minutes was able to watch a quick video tutorial. It was amazing all the topics available not only in mathematics but in other subjects as well! Now he has another section on the website for students to practice the concepts in math. Teachers can sign up as their coach and view the progress of the whole class and it's all FREE!
Salman Khan explains in a TED Talk last spring how he got started and shares his vision for education using technology.

"Maybe you have already seen this but I am flipping out over this website I found. It goes with the NWEA scores. Find your student's area(s) of weakness. Click on the range for their score and it takes you to online games to practice that area."
It is free and the content has four levels of non-commercial, educational permitted uses.
There is a way to search, flag, organize and store the material.
After you explore 3 of the resources, you will be prompted to register, but it is free and share-able.
Thanks to Susan Trott for sharing this resource!
