#MathArtChallenge Day 26: Golden Spiral

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 golden spiral,

MATERIALS: Grid paper? Writing utensils.

Use grid paper. (Or not? Might be a neat wonky one if you don’t?)

Start with a 1×1 square and another next to it.

Using a 2 unit long side, create a 2×2 square.

Then a 3×3, etc.

When it’s as large as you like, draw connected quarter circles to form your spiral!

THE CHALLENGE: Dave Richeson came up with a brilliant extension for Day 14

MATERIALS NEEDED: paper (grid?) and pencil!

#MathArtChallenge Day 18: Celtic Knots

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: Create a Celtic knot, and do some wondering about why you got the number of links that you did. Can you predict how many links you’ll get? (I wrote another blog post on this a while ago, but only go there if you need more examples, because I reveal a lot of the good stuff in it: Knots, Links, & Learning)

MATERIALS NEEDED: Paper, pencil. If you have grid paper, that might help, and here is some special grid paper you can use courtesy of Justin Aion.

Here is a visual set of instructions, and below that is a video tutorial.

THE CHALLENGE: Create a Mondrian artwork (maybe with a goal of getting the lowest score?) Here’s a Math Pickle article to get you started.

MATERIALS NEEDED: Writing utensil and paper. (This would be fun with chalk!)

Above is my attempt at a 6×6 grid. I do not yet, I believe, have the best solution, but it’s okay. Stay tuned for a bonus twist to this one today!

#MathArtChallenge Day 14: Hitomezashi stitching (Suggested by Katherine Seaton)

Thanks to Katherine Seaton for sharing this idea!

THE CHALLENGE: Using grid paper, assign each row/column a 0 or a 1. Then “stitch” both ways. You could assign the 0s and 1s as you prefer, or with a coin, or you could code something in binary!

MATERIALS NEEDED: Grid/dot paper (You can print some or make some without too much trouble), or if you have the stitching materials…

Here’s a brilliant long form tutorial from Neil Butler, if that helps!

And here is a brilliant way for you to adapt this to teach experimental probability:
