"Pinterest lets you organize and share all the beautiful things you find on the web. People use pinboards to plan their weddings, decorate their homes, and organize their favorite recipes.Best of all, you can browse pinboards created by other people. Browsing pinboards is a fun way to discover new things and get inspiration from people who share your interests." (From Pinterest.com)
They left off that it is an awesome way to find ideas for your classroom, as well as new blogs to read. I love reading blogs by Elementary School teachers, but I follow so many that sometimes it's overwhelming. The great thing about Pinterest is that it is in picture form and if you want more information, it just links you to a website!
I could honestly stay on it for hours, but I have gotten so many awesome ideas! You should check it out if you haven't already!
