David Drymiller, Morgan Park High School  
A geometry lesson designed to teach students to find the sum of the interior angles and the sum of the exterior angles of any polygon; review linear measurement to the nearest sixteenth of an inch and angle measurement to the nearest degree; and construct a polygon and its exterior angles given the number of sides. From the Geometry and Measurement section of a collection of almost 200 single concept lessons by the Science and Mathematics Initiative for Learning Enhancement.
