## #MathArtChallenge Day 7: Cardioids!

The #MathArtChallenge is just a fun, simple way to engage our brains during this time of unease. All tasks are low tech: paper, pencil, maybe string. Nothing fancy. I would LOVE to see what you come up with. Post on social media with the hashtag #MathArtChallenge!

THE CHALLENGE:

MATERIALS NEEDED: Paper, circle to trace (yogurt or oatmeal lid?), writing utensil, straight edge (doesn’t have to be a ruler, could just be a piece of cardboard cut straight or any other number of things.

## #MathArtChallenge Day 6: Circle Toruses!

The #MathArtChallenge is just a fun, simple way to engage our brains during this time of unease. All tasks are low tech: paper, pencil, maybe string. Nothing fancy. I would LOVE to see what you come up with. Post on social media with the hashtag #MathArtChallenge!

THE CHALLENGE: Find a smaller circle you can trace. Then trace large circle to use as a guide. Finally, trace a bunch of smaller circles in a ring to create a torus (more commonly known as a donut).

MATERIALS NEEDED: Paper, writing utensil(s), circles. The circles can be whatever, but rigid is helpful and even better if they’re empty (masking tape is great!)

Here are mine!

## #MathArtChallenge Day 5: Probability designs!

The #MathArtChallenge is just a fun, simple way to engage our brains during this time of unease. All tasks are low tech: paper, pencil, maybe string. Nothing fancy. I would LOVE to see what you come up with. Post on social media with the hashtag #MathArtChallenge!

THE CHALLENGE: Use something like a die or a coin to get random outputs. The probabilities don’t need to be equally spread! Assign a design to each output, and then get to designing. I have two examples for you below.

Huge thanks to Emily Lynch Victory for the inspiration for this challenge. She’s a fantastic mathematical artist that I met a few years ago at a math teacher conference, who had a piece like (but far superior!) to my first one below.

MATERIALS NEEDED: Honestly, whatever you want. There are endless possibilities on this one.

Example 1: Roll a die, design a grid!

I assigned a design to each of the 6 outputs of a regular die, and then rolled the die to figure out how I should color in a 6×6 grid.

Example 2: Crochet!

Here I flipped 2 coins and assigned each of the permutations a type of crochet stitch. I made each row 10 stitches long, and switched stitches each row. In the end, I made it into a mÃ¶bius strip, because that’s just cooler.

HH: single crochet

HT: half double rochet

TH: double crochet

TT: Triple crochet

## #MathArtChallenge Day 4: Hyperbolic Geometry

The #MathArtChallenge is just a fun, simple way to engage our brains during this time of unease. All tasks are low tech: paper, pencil, maybe string. Nothing fancy. I would LOVE to see what you come up with. Post on social media with the hashtag #MathArtChallenge!

THE CHALLENGE: Fold your very own Hyperbolic Plane from a simple piece of paper!

MATERIALS NEEDED: A square piece of paper. Youtube instructional video below!

## #MathArtChallenge Day 3: Isometric Cube Cutouts

The #MathArtChallenge is just a fun, simple way to engage our brains during this time of unease. All tasks are low tech: paper, pencil, maybe string. Nothing fancy. I would LOVE to see what you come up with. Post on social media with the hashtag #MathArtChallenge!

THE CHALLENGE: Draw a cube by connecting 3 rhombi (see below). Then use only parallel lines to those in the rhombi to embellish the cube.

MATERIALS NEEDED: writing surface, writing utensil, colors?

THE CHALLENGE: Draw as many connected triangles as you can. Goal is to have as many vertices with 7 triangles as possible.

MATERIALS NEEDED: writing utensil, writing surface (paper, whiteboard, whatever!)
