Bansho (Board Writing)

This 8-page monograph explains bansho, a research-informed instructional strategy for mathematical communication and collective problem-solving. Following a brief overview, the article outlines how bansho can be used to plan and implement an effective three-part problem-solving lesson. Bansho can be incorporated into collaborative planning sessions, in which teachers work with partners or in groups within communities of practice to learn about mathematics for teaching. The author provides a sample grade 2 lesson on the development of multiplication concepts and a list of references.

This resource is included in the following PD Collection(s):
CCSS Practice Standard 6Common Core’s Mathematical Practice 6, Attend to Precision, calls for students to be clear in their reasoning, calculation, and communication through the precise use of words, symbols, units of measure, mathematical expressions, and processes. Students recognize various levels of precision and apply them appropriately; they calculate accurately and efficiently. These resources are intended to help teachers and math specialists understand the intent and scope of MP 6 and plan for successful attainment in the classroom. A companion Classroom collection, Implementing CCSS Practice Standard 6, includes resources to help teachers foster this practice with their students.
