In the current era of mathematics standards, whether they are Common Core State Standards or other state standards, effective vertical mathematics teams offer an opportunity for teachers to grow professionally through shared experiences, for leadership to grow among the faculty, and for the school to change its perspective on the teaching and learning of mathematics. At their core, vertical mathematics teams regularly bring groups of teachers across grade levels together to discuss content, pedagogy, and practice in a structured and supportive environment. Establishing vertical math teams creates professional development opportunities for teachers while also improving student achievement. Effective vertical teams provide a structured professional development experience that encompasses the intersection of analyzing and understanding curriculum and content with the practice of teaching focused on student thinking. The author presents strategies that contribute to successful vertical mathematics teams. The primary goal is for teachers' mathematical understandings to lead to student growth.
