107- Where Do Those Polygon Area Formulas Come From?

Thursday, April 18, 2013: 9:45 AM-11:00 AM
103/105 (Convention Center)
Lead Speaker:
Betty B. Long
Co-Speaker:
Deborah A. Crocker

Participate in hands-on derivations of area formulas for polygons such as parallelograms, triangles, trapezoids, and more. We believe students will retain the area formulas longer if they can derive them. Handouts provided.

Presentation Format: 6-8 Gallery Workshop
Grade Band Audience: 9 to 12, 6 to 8
