In May 2017, the four PIs and four research assistants got together in Shelby, Michigan for a weeklong retreat. We were also joined by a videographer for part of the week who was making a short film about the MOST project. During the retreat, the group discussed various aspects of the projects' work and how to finish the goals of the original NSF grant, while making long term plans for the new NSF grant. We also discussed and wrote parts of upcoming conference proposals and papers for publication.

In May 2016, the four PIs and three of the project's staff got together in Park City, Utah for a weeklong retreat. Additionally, we were also joined by an external evaluator for part of the week. During the retreat, the group discussed various aspects of the projects' work and made progress on developing components of the building practice, making long term plans and writing conference proposals and papers for publication.

At the end of July 2015, the MOST project held a two-day professional development session in Chicago for 13 secondary mathematics teachers from across the country. Over the course of the two days, teachers were introduced to the MOST framework to analyze instances of student thinking and to the practice of "building" on instances of student thinking that are MOSTs. Through several activities, teachers practiced articulating "student mathematics" and the "mathematical point" of various instances of student thinking across diverse mathematical content. Teachers then discussed the "appropriateness" and "centrality" of the mathematics in the instance, as well as whether there was an "opening" and the "timing" was right to take-up that instance of student thinking. Teachers also engaged in activities related to the teaching practice of "building" as currently conceptualized by the MOST project.

In May 2015, the four PIs and four of the project's staff got together in the Upper Peninsula of Michigan for a weeklong retreat. Additionally, we were also joined by an external evaluator for part of the week. During the retreat, the group discussed various aspects of the projects' work and made progress on developing coding schemes, making long term plans and writing conference proposals and papers for publication.
