The following image comes from Spirit 2.0 Education from University of Nebraska at Lincoln, this website is funded by the National Science Foundation and apart of the STEM project and the University of Nebraska Omaha. The CeenBoT seen above is apart of the website: http://www.ceen.unl.edu/TekBots/SPIRIT2/ the website is a great tool for teacher and allows classroom resources, assessments, and allows technology and mathematics to be in the same room at the same time. Under the link mathematics, there is a Interactive Database Prototype that is being updated with more lesson plans all the time. There is already about 100 lessons in the math database.
This is a great website for teachers who want to incorporate more technology in the math classroom, there is a wide field for robotics in mathematics since it is just in its infancy. Hope you check out the website, I have seen some of the lessons in action and they are great!
