Right Triangles Unit Lesson Plan
I constructed these lesson plans for a class titled Geometry Survey. Geometry Survey is a geometry class intended for struggling math students. The same main concepts are taught as in regular geometry, but more time is given for students to master the material. The layout of this unit was constructed to go with Chapter 7 of the 2005 Glencoe Geometry textbook. The daily lesson plans are meant to utilize a SMART Board. |
