I recently started Robotics Jr. and HEROs Robotics clubs. My Robotics Jr. students were in charge of teaching ME how to use Dot and Dash. They thought I was not telling the truth when I said, "I hardly know anything about Dot and Dash! I am expecting you to teach me and others your findings!" The students were put into random groups and given a Dash robot, an iPad, and some floor space. We talked about teamwork, creating safe environments, and communication (between human to human as well as human to bots). I caught students going to another group in order to help them with certain app or robot solutions. 

HEROs Robotics is all about teamwork! In this student-centered activity, the teammates are learning to talk to one another clearly, agree and disagree correctly, and create the correct code for the "bot" to complete the challenge.
