If you are using Engage NY module 4 to teach angles, use this for Lesson 9. The Smartboard pages follow through the concept development and the problem set. It also includes three examples of what is required for the students to complete for homework. This Smartboard page walks you through the entire lesson. Also, in my classroom, I print out the first 7 pages so the students have something in front of them during the instructional part of the lesson. After, I attach the worksheets from Engage NY and the homework as well to create a daily packet.
