I think we could all love a web site that made looking for resources a little faster, and Awesome Library has 37,000 organized web resources organized into neat and tidy categories.
Each category is then further broken down eventually leading to oodles of useful links! Definitely a great prep tool for teachers, the site includes links to lesson plans, project ideas, worksheets and online activities!
By the way, I found this cool tool for teachers simply by reading a tweet containing a link to the blog, "Techy Things Teachers Should Try". I told you that Twitter could be useful!!
