Geometry (Class 89)
Lesson Title
All Together Now
Overview
The warm-up for today’s class asks students to create a mind map with a triangle at the center. The map is intended to represent what was studied this year and how it all centers around the triangle.
The lesson for the day asks students to think through all of the various methods we have developed for solving a triangle (finding angle and length measurements). Students then make a flow chart to represent a process for determining which method to use for any given situation. Finally, students are presented with a number of “solve the triangle” problems on which they can put their flow chart to the test.
