If you're looking for a way to connect with other classrooms across the country or even the world, there are a couple of ways to do so.
The first way is by joining a project hosted by Projects By Jen. The best part is, Jen has been doing this for quite some time, and knows how to run a project without any hitches. All of the information is available with enough time to decide if the project is right for you and your students. My students recently participated in O.R.E.O (for the second year) and particularly enjoyed Where the Wild Things Went, as it was timed well with the theatre release of Where the Wild Things Are. Check out Jen's website to see if there is a project coming up that suits you and your students!
