This lesson study is the culmination of work begun during a full day workshop on Tuesday, January 28, 2020. You can register for that session and/or this lesson study here.
Teaching with coherence in mind means recognizing the ways in which new learning builds off previous understandings. In a coherence cycle, participants are invited to develop their own understanding of content and pedagogy around a particular mathematical topic, through the lens of coherence.
This coherence cycle invites participants to explore the operation of subtraction. What is the meaning of subtraction? Can you add to subtract? How does taking away relate to finding the difference? During this lesson study, teachers will collaboratively investigate these questions. A lesson observation will be the focal point as we discuss ways educators can structure their practice with coherence in mind.
