Favorite Internet Teaching Resource Site

There is a new site that I have been shown in class a few days ago that I extremely like. Once you get on the site and you are there for whatever reason, whether it be a lesson plan or unit plans or activities. There is a search bar so you can find whatever it is you specifically want. I selected The Scholastic site over the others because it seems more organized to me than the other ones and I only want to look at one thing specifically and I can do that with the search bar and filtering it.
