Fantasy Maps to Planets

For those that have created fantasy maps using previous posts here, in classes, or elsewhere in Worldbuilding, D&D, or art, I created a small script to see your maps as spherical planets. You can click to rotate and move the mouse off the canvas to have rotation. You may want to draw a map that […]

Mathober Doodles

This year, I hope to do mathy sketches as inspired by John Golden’s tweet. Initially this post was working off of prompts from another website, and after learning of some controversy, I have decided to rename and recenter this post and month to Mathober. A learner brought up the issues with a tradem

Random Math Poetry

I think the challenge here is to find the math that can fit the poetry… If you want a browser tab version, click here. You can also edit it and change the words as well. Below is the codepen: See the Pen OJNKQmE by Sophia (@fractalkitty) on CodePen.

From the Void

Hexagon and parametric spiral play. I find myself doodling with code lately more than with my pen. I have one more scripting algebra post, but feel like I have a much larger library for a pre-calc set of activities. Thoughts? The GIF is too large for this site or twitter, so I stashed it on […]

Parametric Play!

Here are some simple animations with parametric equations. What you see below is a function and its inverse. If you click, you will get another semi-random equation. See the Pen qBZgZvW by Sophia (@fractalkitty) on CodePen.

Foiled by a Foil

I couldn’t resist this GIF for my algebra students. Foiling can be such fun!

Moiré GIF: by Opal

My daughter started playing with moiré in procreate after I fiddled with it in a previous post. You know we breathe math in our home. She wanted to share:

Parallel to a Parabola

I received a question today about what curve is parallel to a parabola. I sat for a minute and realized that it wasn’t another parabola. It required parametric equations (at least if you wanted to keep it simple). That of course lead to code: See the Pen jOqzMJb by Sophia (@fractalkitty) on CodePen.

Hex-a-Sierpinski

So I doodled and was pleasantly surprised when Sierpinski-like triangles formed. I am sure that a million people have discovered this before me, but I felt like I found a magic portal. And that lead to coding (of which is currently a mess, and I will post later). And one more version:

Yay! This blog is in a blog post on the AMS Blog of Math Blogs!

Seriously though, I am honored and humbled by the opportunity to share all the hard work that has gone into creating the materials on this website. I hope to continue growing, learning, and sharing with you all.

Coffee = Donut

I know it is an obvious one, but it’s what I doodled tonight…

Popping Apollonian Gasket

I doodled this GIF after two days of painting the canvas below. I think I am in the process of preparing for my fall classes and students. Art is definitely an outlet – especially when it’s math + art.

Week 52: Math Rocks!

For week 52 of 52 Weeks of Hands-On Math, I couldn’t resist a play on words: Math rocks! This week I encourage learners to share their math in the neighborhood. Create sidewalk chalk art with Fibonacci hopscotch, paint a math rock garden, make a math obstacle course by your home, or have a piece of

Moiré Play!

Moiré is an interference pattern that can occur in physics, photography, art, math, and more. As a photographer and mathematician, I have always enjoyed seeing these artifacts emerge. Today I played with some Moiré animation for fun in p5.js. See the Pen Moire_Play by Sophia (@fractalkitty) on CodeP

Week 51: Block Prints

I love thinking of mirror images when I am block printing. I will never forget the time I printed SPARK backwards on accident for a summer art camp and my kids laughed at the reverse phonics. This week I encourage learners to take a math concept, tessellation, or shape and create a print. Ways to […

Week 50: Flip Books

This week I encourage learners to play with their animation skills. Take a math concept, problem, or design and play with ideas to animate it. Start simple to warm up and then build on the ideas. Flip books are fun. I recommend using thinner paper that can be seen through so it is easier to […]

Week 48: Bubbles!

Pipe cleaners have so many uses and one of the best ways to use them is to make bubbles. This week I encourage learners to build mathematical structures with pipe cleaners, straws, string, or other waterproof toys to create beautiful structures. I used Zometools in some of my classes as well, and th

Rotating Hexagons

This is a p5.js script I started played with as I get ready to post about stop animation in my 52 weeks of hands-on-math. Here is a link to edit code. You may want to play with the angles, number of sides in the polygon, rotation rate, etc. If the javascript isn’t loading, then here […]

Week 47: Math Dance

Get up and move! This week learners can dance their favorite equations, math symbols and concepts. Whatever topic is of interest or in the process of being learned is a great one to figure out the dance moves that go with it. I recommend taking 5 to 10 of your favorite moves and making it […]
