In spite of numerous calls for action, e.g., Executive Office of the President (2010), there have been few efforts nationally to promote engineering education in the elementary grades. Of these, hardly any have targeted underrepresented populations (National Academy of Engineering, 2009, p. 74). The collaboration described in this paper is a significant exception, which could provide important lessons for those seeking to broaden the reach and scope of K-5 engineering education. We will argue for an interdisciplinary approach, which integrates engineering, math, science, literacy and art, and that engages a school and a university as equal partners. Neither of these components has been prominent in the literature on K-12 engineering education.
