Lesson Abstract:

  • I will begin by defining an angle and initiating a discussion on how angles are named. Students will take turns naming angles, using the correct terminology. Next, I will show students how to use a protractor to measure angles. Again, students will each demonstrate use of a protractor before continuing with the lesson. We will then focus on angle bisectors, which divide angles into two congruent angles. Students will be asked to think of real-world examples of bisectors and will share them with the class. In addition, we will work through a few example problems. I will then facilitate a discussion on adjacent, vertical, complementary, and supplementary angles, as well as linear pairs. Students will practice differentiating between them, and will use mental math to calculate complements and supplements before using variables or expressions. We will conclude with a small group activity to reinforce each of the presented concepts. Finally, the students will take the online quiz I designed to support this lesson. Each student will subsequently receive a detailed report concerning their personal online quiz results. Ultimately, I will administer a traditional quiz that I will grade in order to assess student understanding. The pacing for this lesson extends three class periods.
