An explanation of Math Talk from Math Expressions:

A significant part of the collaborative classroom culture is the frequent exchange of mathematical ideas and problem-solving strategies, or Math Talk. The benefits of Math Talk include:

• Describing one’s methods to another person can clarify one’s own thinking as well as clarify the matter for others.
• Another person’s approach can supply a new perspective.
• In the collaborative Math Talk classroom, students can and ask for and receive help, and errors can be identified, discussed, and corrected.
• Math Talk permits teachers to assess students’ understanding on an ongoing basis.
• Math talk enables students to become active helpers and questioners, that creates student to student talk that stimulates engagement and community.
