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:

SA8: Odd and Even
This Scripting Algebra (SA) activity uses even and odd polynomials to create generative art in p5.js. This activity assumes that the skills from SA1-SA7 were introduced (if-else, logical operators, random(), text(), rect(), variables, loop, pow, for, functions, translate etc.). This activity will in

SA7: Directrix and Focus
This Scripting Algebra (SA) activity uses parabolas again to make generative art in p5.js. In SA6, we used the f(x) = ax2+bx+c form for parabolas. In SA7, we are going to take a look at the directrix and focus by using the form: (x-h)2 = 4p(y-k). This is one of my favorite ways to look […]

SA6: Parabola Art
This Scripting Algebra (SA) activity uses parabolas to make generative art in p5.js. Learners will investigate existing code to analyze changes in parabolas, and other features of the output. This activity assumes that the skills from SA1-SA5 were introduced (if-else, logical operators, random(), te
