462- Triangle Treachery: Modeling with Mathematics

Friday, April 17, 2015: 11:30 AM-12:00 PM
156 C (BCEC)


Lead Speaker:
Bob Mann
Anita L. Reid


What happens to the area and perimeter of a triangle as one vertex is moved on a line? This engaging task will use notecards, technology, functions, modeling, and algebra to analyze this geometric context and to produce some surprising results. The mathematical practices and student learning and reasoning will be emphasized.
