This is a little bit out of my realm but I know there are educators who are readers of the site and this might be of interest. LEGO Education at CES 2016 announced the new WeDo 2.0 robotics kit for elementary school students. The updated WeDo 2.0 is designed to teach kids from second to fourth grades STEM basics. There are over 40 hours of projects including physical, life, earth, and space sciences along with engineering and technology.
The core set comes with a programmable Smarthub, motor, two sensors, and 280 building elements, plus software including the Get Start Project which is an introductory experience to the WeDo 2.0 resource. According to TechCrunch, setting up a classroom with sufficient units would cost around $2,000 and it also includes the cost of licensing.
WeDo 2.0 is now available and the software is compatible with PC, Macs, Android and iOS smartphones and tablets.
