Goodbye Red Oak

I often run for mental downtime and stress-relief. On a recent run, I found one of my favorite trees blown over. This tree grew in a cemetery with broad branches and roots consuming the neighboring headstones. This red oak had brought me so much joy. Before I could get to the stump, the park had […]

Foggy Orbits

After covering the unit circle today, I created Foggy Orbits as a quick sketch. Below is the CodePen and above is a GIF. I hope to add this to pre-calc activities with parametric equations eventually. See the Pen jOrJezv by Sophia (@fractalkitty) on CodePen.

Swirled Series Challenge

I decided to join Craig S. Kaplan’s Swirled Series Challenge. I played the last two nights and have some draft GIFs below. I don’t have a ton of time, but it’s stuff like this that relaxes me at night. I look forward to seeing what people come up with. I still need to export a […]

Draft of Knotty Math Tile Code

Here is a rough draft of Knotty Math tile code. Code was adapted from Shaw Wan’s tangram code on CodePen. I am hoping to adapt more tile designs for play. This will not work on touch screens/phones – I’ll have to contemplate an app for that. I am just learning… Drag the tiles below and […]

Mod Fibonacci

Finite Melodies for an Infinite Sequence A few years ago I asked myself how I could play the Fibonacci sequence on the piano. I found that if I divided the Fibonacci sequence by the number of keys I wished to play, I got a set of numbers that would infinitely repeat. I tested this observation […]

The Point? Dimensions

“The Point of Evolution” started as a Mathober doodle and led to this GIF. Dimensions are fun – what do you see? what do you notice? Side Note: I talk about dimensions when covering combining like terms. One analogy – A 3D banana can’t combine with a 2D banana (or whatever noun seems to go […]

Laser Pointer Googly Eyes

I am glad I can amuse myself. This is a simple script that I may integrate into an Algebra class for looking at points on a line. If you want a webpage version for students, click here. If you want code, see below. Click to make more eyes, and you might get freaked out if […]

Fractal Ink to Code

After drawing the fractal prompt today for Mathober, I played around to make it in p5js. Below is the Codepen to play with. I almost feel like it should have a surprise when they align…maybe for another day. See the Pen fractal_Mathober by Sophia (@fractalkitty) on CodePen.

Lune of Hippocrates Clock

After drawing the Lune of Hippocrates yesterday for Mathober, I played around to make a Lune clock today. Below is codepen (p5 is here). I use a lot of these small projects for students to play with in an hour of code group. This one may not be as popular as projecting memes and cats […]

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 […]

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:

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 44: Conics, Orbits, and Projectile Motion

You don’t have to be in high school math to play with conics, orbits, and projectile motion. This week (or month), learners can play with projectile motion, orbits, and conic sections with the activities below: 1.) Slicing cones * Learners can mold cones with clay and slice to see the

Week 43: Circles and Art

Circles are so much fun! This week, I encourage learners to get out their compasses or a circle to trace and start making patterns on paper. Patterns with circles can start simple, but can also get really complex. You can combine your compass with a straight edge and get amazing

Week 42: Perspective

Drawing with perspective is a wonderful way to play with ratios, similar triangles, transformations, and more in math. This week I encourage learners to try to draw with various perspectives. This is a fun activity for all ages and the math can either stay simple or dive into transformation matrices.
