The Challenge: Suggested by Clarissa Grandi, to cut out and construct this flowered dodecahedron. Mine below followed by links to instructions.
Materials Needed: A set of these papers printed and cut from cardstock. (there are other sized pieces available at the links below.
Math concepts you could explore with this challenge: geometric construction, geometry, polygons, polyhedra, symmetry, vertices/intersections
Depending on how you use this activity, you may engage with different mathematical standards. I’ve listed possible connected math content above. Here are a few suggestions for how you might integrate the 8 mathematical practices. Feel free to add your own suggestions in the comments!
3.) Construct viable arguments and critique the reasoning of others. Is it possible to make a similar shape from triangles, quadrilaterals, or hexagons? Why or why not?
8.) Look for and express regularity in repeated reasoning. What symmetries do you see in this final shape?
