Exploring the Practices Underlying Mathematical Reasoning



Students develop mathematical reasoning by engaging in tasks that call on them to develop, justify, and use mathematical generalizations. In this workshop, participants will enhance their understanding of the role of argument and critique play in learning. Participants will create “representation‐based proofs” to make and justify claims about mathematical ideas. Community building will be emphasized as participants engage in problem solving and question their own and other participants’ reasoning and proofs. Participants will come out of this workshop with strategies and tools for fostering their students’ ability to engage in meaningful mathematical discourse.

This workshop is part of the Exploring Concepts in Math Series.
