Even if you didn’t get a chance to attend Joint Mathematics Meetings , you can experience what it’s like to be inside Glen Whitney’s giant structure thanks to #ricohtheta. app2.ricoh360.com/viewer/aeea7bd…. Be sure to click the link above for an interactive experience. #JMM2025

Here's a video set to music of the spherical picture of the octacube structure built by Glen Whitney and Seattle Universal Math Museum at the Joint Mathematics Meetings Meetings. #jmm2025 youtube.com/shorts/8KYe7MS…

The last day of the Joint Mathematics Meetings is always bittersweet because that’s when I get to interact with really young mathematicians, but not nearly for as long as I’d like. 9 yr old boy with an elegant structure he designed completely on his own; girl discovering the #hattile. #jmm2025

At the recent #JMM2025, I ran a contest. “The yellow and green tetrahedra are both completely filled with coffee beans. The yellow one contains 93 beans. How many coffee beans are in the green tetrahedron?” The result may surprise you. #iteachmath geometiles.com/seattle-themed…

Mirrored triacontahedron (30-faces) at the BYLT Basics store at the local mall. This solid was discovered by Johannes Kepler. It is dual to the icosidodecahedron. #mathart #mathematicalart

This #BlackHistoryMonth I’ve been looking at the origins of African American crafts. The pattern in the first picture is inspired by Kente cloth. The cube design is based on the zigzag pattern often seen in African art. #mathart #mathematicalart

Yesterday at the MathHappens booth at Generation STEAM | SDFSE with Chris Nho and blocks by Christopher Danielson and Dan Finkel #iteachmath Click for picture an interactive view app2.ricoh360.com/viewer/30903f6…

Wait for it…this 7 yr old is discovering a new way to play with Geometiles.He’s treating the chain of rectangles as a multi-hinge system, and he finds it “satisfying” to experience the system unfold from a triangle to various other shapes under the effect of gravity.#iteachmath

The San Diego Festival of Science and Engineering was a lot of fun! Chris Nho describes five scenes: mathhappens.org/sd-fest-of-sci…

Celebrating this year’s Pi(e) Day with this fluted number! It comes with its own pie stand, made for the occasion. Watch to see how two flat surfaces come together to make the pie— or should I say PIElyhedron?? Mobies make the thin pedestal of the pie stand possible. #piday2025

Celebrating #nationalquiltingmonth with two classic quilting blocks: the Sawtooth Star and Dutchman’s Puzzle. Geometiles allow you to create these patterns quickly so that you can focus on their geometry even if you don’t know how to sew. See Geometiles.com/quilts for examples.

This pattern was inspired by the Night Sky quilt block designed by Julie Herman .The pattern is made entirely with Geometiles 30-69-90 triangles. #nationalquiltingmonth #mathematicalart #mathart #iteachmath

It's #NationalQuiltingMonth ! What better time to incorporate math teaching and quilting. Read our new blog: geometiles.com/quilting-block…

My most recent homage to #eggs— the bottom is half of an icosidodecahedron, and the top is part of a rhombicosidodecahedron. #mathart #Easter2025 #Passover2025 #priceofeggs
