One of the highlights of OCTM this past week was attending Mike Browne's session on "Introducing Students to Calculus" where he shared this delightful visual that he constructed of unwrapping the area of a circle into a triangle. #octmconnects #ohioctm

It was a great way to wrap up the @nctm.org Annual Meeting presenting on Geometry in @desmos.com. Looking forward to sharing again next week back in Ohio at OCTM!
(For those curious, the slide in the picture was not about Geometry…we got off on a tangent looking at some example graphs)

Excited to head to Atlanta next week for the @nctm.org Annual Meeting!
I'll be representing @desmos.com with a session on dynamic geometry software on Saturday. I’m putting together my agenda of sessions to attend — any recommendations? #iteachmath

Well that's a walk down memory lane.

#MathArt project in calculus class today. Students generated "Reimondrian" art in @desmos.com. (Inspired by @mathzorro.bsky.social). Reimondrian is a mash up of Reimann sums and Piet Mondrian art. Some very creative students. #ITeachMath #MathsToday

Loving these trippy geometric patterns, and couldn't resist recreating these delightful squircles in @desmos.com www.desmos.com/calculator/p...

Will this answer surprise you? Or is it intuitive?

Enjoyed re-creating this visual in the @desmos.com Geometry tool: www.desmos.com/geometry/lx7... #mathsky

Some great strategies here for getting started with #Desmos #Geometry @desmos.bsky.social #MathSky #iTeachMath

Fun one to visualize in #Desmos #Geometry - Given a regular n-gon inscribed in a unit circle, the product of the chords from one vertex of the polygon to all the others is equal to n. www.desmos.com/geometry/pb3...

A delightful Geometry theorem, illustrated using the #Desmos Geometry tool with visual shading and calculations showing the equivalent lengths. #🧮 www.desmos.com/geometry/bpn...

When using custom colors in #Desmos (@desmos.bsky.social), RGB felt straight-forward enough, but I didn't have a clear grasp on what each component of HSV did. Turns out that it's much easier to visualize in 3D.

Seeing lots of Desmos 3D discussion around surfaces of revolution for Calculus. While parametrics are great for showing the act of rotation (see: desmos.com/3d/1a7f86ac77), I'm also loving this strategy, accessible to students who have seen equations of circles before: desmos.com/3d/0439a67934
