This post is a little different them my previous posts.  AirServer is such a great tool to have in the classroom!  It allows you to mirror your SMART board, computer and smart device such as an iPad or smartphone.  It is great for students who have visual impairments and might not be able to see what is projected on the board.  Also it makes the classroom more interactive for those students that may not be able to get around the classroom and interact with the SMART board.  Now everyone can interact with the board by passing around the iPad!  The pricing options are very reasonable!
