The Challenge: Create your own version of Matt Henderson’s triangle incenters.

Materials needed: Paper? Pencil? Origami? Graphing software? (There are lots of options here.) Math conceptsyou could explore with this challenge: angles, geometry, polygons, symmetry, vertices/intersections

The Challenge: Using rules from the “above row”, create a new row below.

Materials needed: grid (can be home made!) paper, pencil/pen. Math conceptsyou could explore with this challenge: Probability, randomness, expected value

Materials needed: Patience, paper, some sort of pen/flat thing to sharpen creases. Math conceptsyou could explore with this challenge: geometry, origami, symmetry

The Challenge: I’m seeing the trees start blossoming around here (MN) so this felt like a good time for this one. I used Samira Mian‘s instructions. If you’re interested in Islamic Geometry, I cannot recommend her enough. Here is my creation, followed by her youtube video.

Materials required: Compass, straight edge, pencil. Math conceptsyou could explore with this challenge: circles, geometric construction, Islamic geometry, symmetry, vertices/intersections

Materials needed: Skewers, Tiny rubber bands (I was able to get skewers at the grocery store and polybands from Target) Math conceptsyou could explore with this challenge: Angles, geometric construction, lines, symmetry, topology, vertices/intersections

The Challenge: Represent a pattern of permutations

Materials Needed: ??? There are so many options here. I used paint, but you could draw, use yarn, legos… anything. Math conceptsyou could explore with this challenge: combinations & permutations, counting

The Challenge: Make the Origami Firework, but this time, only use ONE PIECE OF PAPER.

Materials Needed: A long piece of paper, patience, and the knowledge that I BELIEVE IN YOU. Math conceptsyou could explore with this challenge: angles, origami, symmetry

The Challenge: Can you find the 4, 5 and 6 crossing knots?

Materials needed: Patience, creativity, paper, pencil, maybe some strips of t shirts and a safety pin? Math conceptsyou could explore with this challenge: Combinatorics & permutations, counting, graph theory, knot theory, topology, vertices/intersections
