563- Equivalent Figures: Deriving Area Formulas by Composition and Decomposition

Friday, April 17, 2015: 2:45 PM-4:00 PM
Grand Ballroom C (Westin)


Lead Speaker:
Emily R. Keebler


Must area formulas be memorized and applied by rote? Boost your students' engagement and understanding of area by inviting them to compose and decompose plane figures into equivalent or related figures. Learn to use these figures to derive area formulas for right triangles, other triangles, special quadrilaterals, regular polygons, and circles.
