TED Talk: Where do math symbols come from?- John David Walters

This TED-Ed companion resource explores the origins and purpose of mathematical symbols, revealing how they function as a language designed to simplify and communicate complex ideas. Students learn where symbols like the equals sign, plus sign, exponents, and sigma notation came from and why mathematicians rely on symbolic shorthand. The resource includes 20 discussion questions, a structured debate with clearly labeled positions, and two essay-writing options: a fully expanded, evidence-bas

Zach's Eraser: Linear Functions and Line of Fit

This is an effective and thought-provoking way to helps students apply functions to real situations. The resulting function shows a negative slope. Though it is a simple linear function, the data is not perfect, so a line of fit must be employed. Because it is based on real data, even students who have only a beginning experience with functions can understand the concepts and mathematics. The lesson can incorporate slope-intercept and point-slope forms as well as independent and dependent variab

Trundle Wheels -- Free! Hands-on Applied Math and Map Skills

Trundle wheels are a simplified version of a surveyor’s wheel. In this basic student edition of the trundle wheel, students roll their own version of trundle wheels across all sorts of things. They work especially well to measure curved surfaces or for applying a map’s scale of miles on highways. A bonus to using trundle wheels in the classroom is that students must apply math skills to convert their measurements from the revolutions of the trundle wheel to yards, feet, inches, meters, centim

This handout is used to help the students convert Binary Code into Base 2 numbers. 0's mean off, 1's mean on. Instead of using Base 10, teach the students base 2, convert, and perform the functions. This is the final product after a study of Binary Code and Base 2. There are quite a few lessons online with Binary and Base 2, but I created this to go with what I found online.

Ciphers and Codebreaking (mini booklet)

Originally written for Algebra 2 students as a fun end-of-year after-testing activity. It's a lighthearted take on the subject but includes some more serious math. This is a 58-page mini-textbook that covers some basic elements of classical cryptography, including Caesar, vigenere, affine, and keyword ciphers, among others. It discusses modular arithmetic, solving algebraic equations with modular arithmetic, and some basic work with prime numbers (coprimes, Ulam's spiral, Mersenne Primes). The
