#MathArtChallenge 97: Tomoko Fusé’s Bird Tetrahedron Origami

The Challenge: Make an origami sculpture using Tomoko Fusé’s text Multidimensional Transoformations Unit Orgiami. (I used instructions on pgs 134, 138-139.)

Materials Needed: Paper (origami paper is handy, but any paper will work) and scissors/paper cutter.
Math Concepts: 3 dimensional building, angles, space filling, rotations, proportions

#MathArtChallenge 95: Magic Squares

Overhead view of lego towers arranged in a 3×3 grid.

The Challenge: Create a magic square. Bonus points if you make it a physical thing.

Materials Needed: Legos, blocks or coins all work well for making these towers. Could also be pen/pencil & paper, of course.
Math Concepts: Algebra, arithmetic, counting, proportions/ratios, structure, sum of 1-n integers

#MathArtChallenge 90: Sand Piles

The Challenge: Explore a toppling sand pile.

Materials Needed: Paper, pencil, and probably a good eraser. You could also do this using a whiteboard or other writing surface.
Math concepts you could explore with this challenge: algebra, arithmetic, counting, fractals, functions isometric, proportions/ratios

#MathArtChallenge 89: Voronoi diagrams

Voronoi Diagram Sketched in Notebook

The Challenge: Throw some random points (or carefully selected ones!) on a plane. Identify the parts of the plane that are closest to each of those points.

Materials Needed: Paper, ruler, writing utensil.
Math concepts you could explore with this challenge: algebra, arithmetic, geometry, lines, proportions/ratios, slope, tessellations, vertices/intersections.

#MathArtChallenge 88: the Recamán Sequence

The Challenge: Create a visual (or audio?) of the Recamán sequence, created by a Colombian mathematician, Bernardo Recamán Santos (who seems to have very little biographical information out there??). I was first introduced through Alex Bellos and Edmund Harris’s book.

Materials Needed: Straight edge, maybe a compass, maybe a ruler. Paper, riting utensil.
Math concepts you could explore with this challenge: algebra, circles, counting, functions, proportions/ratios, randomness, sequences

#MathArtChallenge 84: Tangrams

The Challenge: Get yourself a square of paper (or something else?) and cut yourself a set of tangrams. Then create away!

Materials Needed: Scissors, paper
Math concepts you could explore with this challenge: angles, geometry, lines, polygons, proportions/ratios, symmetry, tessellations

#MathArtChallenge Day 72: Stars

A number of hand drawn stars.

The Challenge: Create all of the possible “stars” given a certain number of vertices.

Materials Needed: Pencil/paper
Math concepts you could explore with this challenge: angles, arithmetic, circles, combinations & permutations, lines, proportions/ratios, symmetry, vertices/intersections

#MathArtChallenge Day 71: Sona Drawings

Given what’s happening in my community right now, I felt it was necessary to highlight some Black brilliance today.

The Challenge: (Re)create a Sona drawing. I did a couple hours of research yesterday (which is totally insufficient to fully understand it), but what I can tell you is that these drawings originate with the Chokwe people in southwestern Africa, specifically Angola and the southern part of the Democratic Republic of the Congo. The drawings are told in conjunction with a story, and the goal of most is to draw them in as unbroken a line. Please check out some of the resources below, and if you have others to add, I’d love to see them and link them here.

Materials Needed: grid, pencil, paper, perhaps graphing software.
Math concepts you could explore with this challenge: angles, counting, geometry, graph theory, proportions/ratios, slope, symmetry, vertices/intersections

#MathArtChallenge Day 67: Circular Celtic Grid

A circular pattern within a circle.

The challenge: To create this circular grid and then design using it.

Materials needed: Compass OR Desmos geometry.
Math concepts you could explore with this challenge: circles, proportions/ratios, symmetry

#MathArtChallenge Day 64: Anamorphic Raintangle (from woollythoughts.com)

The challenge: Create a rainbow and get it reflected in a curved surface to reveal a rectangle. All credit here to Woolly Thoughts! (They have wonderful things for you to play with there.)

Materials needed: I crocheted mine, which was a fun puzzle to get an even rainbow. They have knitting instructions on their website, but you could just as easily draw this with markers. I used tinfoil as my reflective surface wrapped around a nail polish remover bottle. I bet you all get more creative than myself.
Math concepts you could explore with this challenge: circles, geometry, perspective, proportions/ratios
