“Using Explain Everything to Demonstrate Math Concepts” explores the power of recording video artifacts during class. By posting these videos online, students and parents can access these resources at any time. This allows them to re-watch the explanation of a concept as many times as needed, and models for students how to explain their own thinking. This also prepares students to record their own videos that they can share with their teachers and classmates. This book walks teachers through the steps to record, and post effective videos.
