Triangle Perimeter and Area: Around and Through

This is one lesson in a larger Unit Plan that covers many properties of triangles and several other theorems. It has proofs, real world problems, constructions, a unit project, assessments, and more. Lesson 8, Around and Through, students investigate the relationship of triangle perimeter and area, including real world connections. Includes lesson plan and rubric. The entire unit plan can be found. This is a portion of a Unit Project, however, it could be used as a stand alone assignment as well.
