" I have been a teacher and in education since 1998.  I have taught in over four states and more than 12 schools.  I have also worked at a publishing textbook company that makes curriculum materials for the classrooms in elementary school. The intent and the design is nice, but this is not PRACTICAL at all in the public school setting.  This is a complete distraction for the kid who is supposed to use it and for all the other sutdents who is not using it.   Why would the public schools spend tax dollars to purchase this for classrooms?  Maybe for individual private homes or even private schools.  I don't know where your research is from and how much background knowledge you have on classroom management and classroom settings.  Please maybe consider this to be used in a work space, outside of the public school classroom setting.  "
