## Reflection: Lesson Planning The Pythagorean Theorem - Section 2: Launch the Pythagorean Theorem and Prove It!

Most students in my classroom have seen the Pythagorean Theorem before entering my classroom, which has several benefits and drawbacks.  While exposure to the Pythagorean Theorem is good—most students recall that the theorem has to do with triangles—students often have misconceptions around the most important ideas and have little understanding of what “a,” “b,” and “c” even represent.

In creating a PowerPoint for today’s lesson, I realized I had created an organized structure through which I could keep my lesson moving forward while staying focused on the most important conceptual ideas.  I did not get bogged down or distracted by students’ questions and confusions, nor did I give much time for students who had a strong grasp of this content to be bored; I was able to stay focused on reinforcing the most important ideas of the Pythagorean Theorem: that the theorem describes a relationship between the sides of a right triangle and that “c” must always represent the length of the triangle’s hypotenuse.  I was also able to help students visually and kinesthetically understand that the converse of the Pythagorean Theorem was also true because of my PowerPoint’s clear directions and structure.
