Formative Assessment Collaborative Team (FACT) meetings provide educators with a structured time each week to engage in peer collaboration focused on students' mathematical thinking. In these meetings, educators work together to analyze their students' mathematical thinking and make purposeful adaptations to instructional plans based on the insight gained through the process. The FACT meetings use a structured protocol and weekly record-keeping documents to focus the topics of discussions, provide a mechanism for accountability, and promote consistency of the process across teams of teachers.
