On August 16 and 17 we held a two-day collaborative meeting at the Center for Research in Mathematics and Science Education. In attendance where three teachers and our reteach team. Our goal was to summarize early insights from our work in academic year 2016-17 and to prepare for our work in 2017-18. The meeting was also an opportunity for us to say thank you and goodbye to students who were wrapping up their work on the project, and to welcome new student assistants.
