The Challenge:Make a chair fractal (That link will take you to the originators blog post about it. Seriously, go. It’s GREAT.)

Materials Needed: paper, pencil Math conceptsyou could explore with this challenge: fractals, geometry, symmetry

Step one. Dig in to the base grid of a chair fractal.

Step two. Decide on a way to embellish each L shaped fractal piece.

Enjoy!

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!

1.) Make sense of problems and persevere in solving them. Is there a guaranteed rule for how you could make this using a rectangular grid? Why or why not?

2.) Reason abstractly and quantitatively. What fraction of the pieces are rotated in which direction?
