We used this task to teach teachers about how to use a Talk Frame in their instruction to begin lessons that support argumentation. The main objective was to develop teachers’ understanding of how to use the Talk Frame in order to give students the opportunity to first work independently, then as a group, then for groups to present 3 distinct approaches/strategies to problem solving and finally to critique each other’s mathematical argument. This task required teachers to experience participating in a Talk Frame from the lens of the student. They needed to work with their groups to select a strategy, provide evidence of how the strategy got them to their solution, and finally to come away with some understandings either about Talk Frames or around the actual content of the problem.
