Extreme Collaboration from SMARTBoard is FREE right now.  Extreme Collaboration is simply a neat way to connect learners using the SMARTBoard.  There are a lot of great, FREE web-enabled collaboration resources out like Socrative, InfuseLearning, and SimpleMeet.ME.  But how Extreme Collaboration differs is that students will be working and or answering questions together.  Educators can show how said what or leave that information private.  Students can also send images along with your text.  I think Extreme Collaboration is a great way to brainstorm and work on a common goal.  If you would like to learn more view the quick video below or click on the image to be directed to the Extreme Collaboration site.  Download the SMART Notebook Add On here.
