Last year, Annandale Terrace Elementary School (Annandale, Virginia) began exploring professional learning communities (PLC). In this article, two of Annandale's math coaches share the school's journey. On the basis of their own reflections, the coaches conclude with some recommendations for those considering embarking on a similar journey including: (1) Front load materials and tasks to support teachers as they build collective knowledge; (2) Collaborate with someone else during the planning stages (a coach of a different subject area, an administrator, a districtwide support person); (3) Make a realistic goal that is meaningful and will move the team forward; (4) Be sure the physical environment encourages communication among the teams; (5) Focus on opportunities and potential. Be solution-centered; (6) Do rich math tasks with teachers! This is imperative for engaging the teachers as well as building a common understanding about what students must know and be able to do.
