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 conceptsyou 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?

This is awesome. Thank you so much for sharing.
