Day 22: Extending Day 14…

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

MATERIALS NEEDED: paper (grid?) and pencil!

#MathArtChallenge Day 20: Origami Icosahedron

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 30 identical pieces of paper to put together as an icosahedron.

Day20 Icosahedron

MATERIALS NEEDED: 30 square pieces of paper. No problem if it’s not origami paper, you can use regular paper (and you can decorate it if you want!)

#MathArtChallenge Day 19: Alternating 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: Draw an alternating knot. Then see if there’s any way to draw a looping line that cannot be turned into an alternating knot.

MATERIALS NEEDED: Pencil & eraser, or whiteboard, or markers?

#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 your very own order 4 Permutohedron (see video below).

MATERIALS NEEDED: Paper, pencil, patience, and if you want to go 3D, you sure can.

Here you go. This is a flattened version of the answer, but it’s really satisfying to find. If you were to build this in 3D you would get a truncated octahedron. Every permutation should be connected to 3 other permutations.
