| lesson 5 7 the pythagorean theorem answers: Video Pedagogy in Action Mary B. McVee, Lynn E. Shanahan, H. Emily Hayden, Fenice B. Boyd, P. David Pearson, 2017-12-12 Combining video analysis with the well-known Gradual Release of Responsibility (GRR) model, this book offers teacher educators a fresh perspective and a new tool for supporting teachers’ learning and reflection. The clearly articulated and useful framework shifts the focus away from children and toward teachers’ thinking about their own teaching practice. Interwoven with practical examples of the framework in use, this book identifies ways that teachers and teacher educators can foster more productive kinds of reflection about video-recorded classroom interactions and support preservice and inservice teachers. Offering key tools such as templates for reflection, video viewing guides, self-analysis checklists, and activities, this book moves the field forward and establishes video reflection and the GRR process as critical tools for teacher reflection, professional development, and effective teaching and learning. |

Because the triangle in #2 is a right triangle, I can use the Pythagorean Theorem to solve for z. I knew I was solving for a leg, so I can put z in for “b” in the Pythagorean Theorem. I set up the equation as 7 2 2+ z = 25 and solved to get z = 24. The answer should include: Using the Pythagorean Theorem because it’s a right triangle
