If you ask students, “Why does that work?” do they know what you’re asking and do you know what to listen for in their responses? Do you have images of what mathematical argument looks like in the elementary grades and how to help students learn to engage in this important practice? Do you have so much content to cover that finding time for this kind of work is difficult?
Enhanced with extensive video showing the instructional sequences in action—along with guiding focus questions and math investigations—But Why Does It Work? is a flexible approach that will help students confidently articulate and defend their reasoning, and share their deep thinking with others.
