I use the 3-Part Math Lesson routinely in my classroom. Students gain confidence while working through problems with math partners, are able to communicate about their learning through a math congress, bansho or gallery walk, and can share their expertise independently through exit slips and other formal assessments.
More information regarding bansho (board writing) and communication in the mathematics classroom can be found in the Literacy and Numeracy Secretariat Monographs:
Bansho (Board Writing) - February 2011
Communication in the Mathematics Classroom - September 2010
