Equal Area Demonstration

Last week the UAF Kuskokwim Campus had a workshop with Jerry Lipka and Dora Andrew-Ihrke from UAF’s Math in a Cultural Context program. We talked about the Yup’ik ideas of math as measuring, halving, and measuring in two dimensions. I made this video to help demonstrate that these two shapes, and isosceles right triangle and a rectangle, constructed by folding from a square, have the same area.
