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

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.
