LEGO education offers several kinds of robotics systems designed specifically for educational use: WeDo, Mindstorms (NXT & EVO), and Tetrix. WeDo is advertised for elementary level, but can be used at middle school with some extensions, such as those I offer in this Curriki collection. WeDo is particularly accessible for disadvantaged students who may have little prior experience with LEGO products, mechanical construction, or computer use.
