On the Cover: Find Mathematics in Butterflies Using construction paper colors of their own choice, have students cut out and combine triangles, parallelograms, trapezoids, rhombi, regular polygons, and/or sectors of circles to create a butterfly. Follow up questions: - What is the area of the butterfly (the composite figure)? - What proportion of the area of the butterfly is _____________________? o Examples: What proportion of the area of the butterfly is parallelograms? What proportion of the area of the butterfly is kites or sectors of circles? What proportion of the area of the butterfly is red? Have students draw a butterfly on their coordinate plane. This can be done on graph paper or with graphing programs such as Desmos (www.desmos.com). You might require: - Linear functions - Quadratic functions - Restrictions by domain - Restrictions by range - Conic sections - Parametric equations Brandy Crowley, Baylor University * Brandy_Crowley1@baylor.edu Ryann Shelton, Baylor University * Ryann_Shelton@baylor.edu We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering and technology. And there will always, always be mathematics. Everything is physics and math. ~ Katherine Johnson, born August 26, 1918 1966 2008 22 | Spring/Summer 2018 Texas Mathematics Teacherhttp://www.desmos.com
