SA5: Systems of Equations

Scripting Algebra

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

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

SA3: Exponents

Exponential growth can be visualized so many different ways. This SA activity will play with the pow function and explore exponents in p5.js. This activity assumes that the skills from SA2 were introduced (if-else, logical operators, random(), text(), rect(), variables, loop, etc.). Make sure that t

SA2: Animated Lines

There are infinite possibilities for linear function animations. This SA project will give some ideas to practice using linear equations with p5.js. Introduce if-else statements (conditions), logical operators, random(), text(), rect(), variables, and using p5.js for animation (loop). Below are a fe

SA1: Real Numbers

Here is my first Scripting Algebra (SA) post! I hope to keep these coming (with about 5 posts for each semester of Algebra). Often Algebra classes start with the Real Number System. This SA task is to program a graphic for the Real Number system. This can be a Venn diagram, animation, or another pro

Week 49: Pendulum Labs

Pendulums are wonderful physics toys that are great for exploring periodic functions. For week 49, I encourage learners to get out some string, weights, and stop watches. Here are some ideas for playing with math and pendulums: * Start with a string and a weight to observe basic pendulum motion. Nuts,

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 […]

Sticky Note Sunflower

What you are seeing is a growth pattern of sticky notes that uses the Golden Angle (137.5 degrees) and then slowly decreases. This angle is commonly found in the plants all around us because it is an optimal angle for growth. It was a lot of fun playing with the growth angle while creating memorizin

I’m Attracted to Attractors

So many plots and mathematical musings throughout my life have brought on a sense of artistic beauty and awe within my being. In the windowless halls of engineering firms I have smiled at harmonics, or in a homeschooling room squealed in glee when I stumbled upon Pisano periods by trying to play Fib
