Gross-Beak

I got side tracked when thinking about the next math bird in a series and thought “I’m long overdue for a kitty comic.” Dozen=12 and Gross=144

a list of mathober prompts

Get Ready for Mathober!

This year’s Mathober pieces will be posted here. Last year I posted prompts for the first year of Mathober when I wanted to do some daily doodles with no strings attached. The activity was a lot of fun. There were some some great pieces from John Golden and Foldster on Twitter. Prompts this year hav

The Point? Dimensions

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 […]

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 […]

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

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

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

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:

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 39: Toothpicks

A box of toothpicks can lead to an afternoon of entertainment. This week learners can play with the toothpick sequence. The sequence produces really interesting geometries and lines as it grows. I recommend watching Numberphile’s Youtube video on this sequence here. There is also OEIS’ website that allows for

Week 38: Knotty Math Tiles

I love playing with knots. Last year I designed a Knotty Math toy with wooden tiles. It is part of a series of toys I have been working on that help create single pointed mindfulness with math. These are for kids and adults alike. I think sand, clay, tiles, and

Week 25: Loopy Doodle Math

Doodling and math? Yes, we can play with doodles and see what patterns emerge. Finding patterns and problem-solving are big parts of math. For this week’s hands-on math, learners are going to draw a loopy doodle where they start and end at the same point without lifting the pencil
