Lesson 2 Duration of Lesson: 120 minutes Content Standards: CCSS.MATH.CONTENT.7.G.B.5 Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure. CCSS.MATH.CONTENT.HSG.CO.B.8: Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions. Standards for Mathematical Practice: CCSS.MATH.PRACTICE.MP1 Make sense of problems and persevere in solving them. CCSS.MATH.PRACTICE.MP3 …show more content…

Material Management: We will begin class with a warm-up that will be displayed on the projector. After discussing the warm-up we will move into our “Triangle Congruences and Rigid Motion Notes,” packet. In the packet we will go over some notes and examples directly in the packet. As the students and I work through the packet together, I will be projecting it so that everyone can follow along. We will then take our whiteboard and do some individual practice. Once completed we will put all of the materials away where they belong. Lastly, they will get an exit slip and complete by the end of class. Grouping Structure: For the warm-up they will start individually, then proceed to groups and finally end with a whole class discussion. While working in the packet we will work through as a whole class and will have sections where they will collaborate in groups and as pairs. For the exit slip they will work individually, in order for me to assess their understanding of
