Students computer programming with Spheros

Hi,  my name is Jon Sharp and I am a teacher at Walt Clark Middle School in Loveland, CO.  Our school is a STEM school, meaning we have a strong Science, Technology,Engineering, and Math focus.  I am currently teaching a computer programming class as my STEM class.  The students are doing great, but they are interacting with just the computer screen.  I am wanting to get them up and active and have found a great way to do this.  The Sphero Bolt programmable toy will allow my students to use 21st century skills while programming their Sphero's to manipulate complex mazes.  The Sphero's run about $150 each.  I am looking to purchase 6 of these to get my class started.  We will have a new round of STEM classes starting in January and I am hoping to be able to switch over to this more hands on class.
