Thank you @Fanchen2007 We are so happy to have this partnership with @LaNube915

[Fan Chen @fanchen2007]

The Math Room officially launched today at @LaNube915! Before the opening, Matt from @MathHappensOrg gave our facilitators a quick hands-on training to get everyone ready to bring playful mathematics to our community. Let the math fun begin! #PlayfulMath

[MathHappens @MathHappensOrg]

We are so excited to have @fanchen2007 working with us on this math room!

[Fan Chen @fanchen2007]

A dream years in the making! @MathHappensOrg + @LaNube915 are bringing a Math Room to El Paso, and I’m honored to coordinate it!
Launch: Saturday, Oct. 17

We just found out from John Chase that Bubble Tiles are now in something cool called the Tiling Atlas. These are the 3 sided and 4 and 6 sided tiles as well as the OGin so many cool combinations. Check out all 52,140 here: https://t.co/fQ4wPnfoRE I Hope you like bright colors!

Surprise -- I Found some 90degree Bubble Tiles in the wild. Its a hotel balcony in San Diego. Read how to make all kinds of Bubble Tiles in the 2025 Rosenthal First Prize lesson - link in the educator resources section https://t.co/H1HR3y6yth.

These four tiles are related by the Pythagorean thm and we can make Voronoi type regions with them.
