Since we’re already in an abnormal school year, why not engage students with fun tasks that promote deeper conceptual understanding? No calculus needed: GeoGebra 3D Calculator= a great app for students to build, model & explore! Below we create a torus (donut) to model a piece of a playground swing without using any higher level mathematics. Upper elementary, middle school, and high school students can create real world objects like this in GeoGebra 3D Calculator. And it's fun!
