I'm not planning to join Threads. I tried Mastodon and didn't care for it. Not feeling great about Twitter either lately. Not sure what this means. I might extend my social media break through the summer.

I've taught geometry for many years. Just discovered this morning how to find the centroid of any polygon. Give it a try in this Desmos Calculator. desmos.com/calculator/ewa…

How to find a center of triangle with linkage mechanism STL for 3D printing is on Cults. cults3d.com/:1340400

🚨New Feature Alert🚨: Our Geometry Tool now includes vectors you can compute with in the expression list! How will you use our new vector tool? (Bonus: What do you notice about the vector tokens in the expression list as we move the vector around?)

Playing around with the origamisimulator.org. One way to fold a square in half. #playwithmath

This game has a nice mix of addition and strategy. Easy to adjust for younger or older players by changing the target number and number of dice. #earlymath #tmwyk #earlychildhoodeducation #learning #mathgames #mathstrategy #mathematics #children #math #homeschooling

Used the Mathigon Polypad to create a blueprint for a Kumiko lantern. More to come...

Ready to start year 30! How can that be possible? I am incredibly blessed to be surrounded with people who motivate and inspire me daily.

Having fun with GeoGebra to create origami simulations at #flggb 2024 Mark Kaercher

It was an honor to be invited to present Origami Simulations using GeoGebra and origamisimulator.org Best of all, I got to hang out with my friend Libo Valencia 🧮 MathPlay!

It was a total honor to be a part of this conference! Hoping to join you all again in 2025!

Enjoyed presenting at the Florida GeoGebra Conference in person for the first time this year! I love being with math teachers who are enthusiastic about teaching with tech intentionally #flggb Florida GeoGebra Conference GeoGebra

In preparation for an upcoming conference, I've been playing with prisms a lot in GeoGebra! Feel free to #playwithmath geogebra.org/m/gkumrnzm
