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

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

SA5: Systems of Equations
This Scripting Algebra (SA) activity will play with systems of linear equations in p5.js. In this activity, a system of two random lines will be generated and the intersection (or solution) of those lines will be calculated to make generative art. It is recommended to introduce creating functions if

SA4: Perpendicular Play
This Scripting Algebra (SA) activity will introduce students to perpendicular slopes and points for lines in p5.js. Once students get comfortable with linear functions, it is fun to look at their perpendicular counterparts. Introduce the concept that a perpendicular line has a slope that is a negati

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
