El ángulo interior de un hexágono regular es 120º.
Se puede ver como la suma de 4 ángulos inscritos de 30º, que son mitades de 4 ángulos centrales de 60º.

Some pundits (and some colleagues) claim we teach too much math. How do we respond? I'll share some thoughts at the CMC-North conference in Asilomar.

Algebra and Geometry for All Students!
December 6, 9:20am

I hope to see some of you there!

What happens when you…?
Can you suggest a way to solve the problem based on what you understand?

Thinking about how we might turn more stories of mathematics education into page-turning reads. I have some ideas… who’s interested in chatting? #iTeachMath

Something exciting is brewing this October at @fieldsinstitute.bsky.social. Think #math, books, and the stories behind them.

Anthony Bonato, @profnoahgian.bsky.social, and I are co-organizing a celebration of popular mathematics, featuring authors who have turned big ideas into page-turning reads.

Pattern block play! #21CenturyPB #iTeachMath
The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six regular hexagons around a central hexagon. All seven hexagons share the same composition and have 4” sides. The first image along the bottom shows a scaled-up equilateral triangle which is used to create the regular hexagon (with 4” sides) shown in the second image. The triangle is made of 1 yellow hexagon, 1 purple hexagon, 2 green triangles, and 2 pink triangles. The three images on the right show the progression of the design.

His words also make a compelling argument for what math and math teaching & learning should be like.

Some inspiring words on cinema in the streaming era from the Pope.

Yes, THAT Pope.
The logic of algorithms tends to repeat what “works,” but art opens up what is possible. Not everything has to be immediate or predictable. Defend slowness when it serves a purpose, silence when it speaks and difference when evocative. Beauty is not just a means of escape; it is above all an invocation. When cinema is authentic, it does not merely console, but challenges. It articulates the questions that dwell within us, and sometimes, even provokes tears that we did not know we needed to express.

#iTeachMath but as a #BlackTeacher w/majority Black students I needed these kids to know that education was once banned for us. Shared this in September. Take all the learning you can babies!

On this day in 1830, North Carolina passed laws that criminalized teaching enslaved Black people to read and that made the repeated dissemination of anti-slavery pamphlets punishable by death.

TIL that architects have their own term for "hyperbolic." We (math) hit these communication walls with many fields. “Anticlastic surfaces are double-curved surfaces which have principal curvatures on opposite sides of the surface.” #iTeachMath #MathSky #MathMakers bamboou.com/building-of-...

This season has been heavy. Leading every day while your own belief feels thin is a different kind of work. It is the version of leadership no one really prepares you for. The quiet erosion no one talks about. The part that shifts how you see yourself while you keep moving. #BlackEduSky #EduSky
When You're The Chain & The Paperclip: Examing Your Own Belief in Leadership
It is early November and every educator is ready for a break. The kids too, if we are being honest. This time of year brings a need for a reset for many reasons. Assessment data comes in and it is not...

I’m grappling with California school districts who refuse to read even the smallest portions of the CA Math Framework in preparation to adopt a new math curriculum.

TBH it feels unethical to spend $$$ without concern for aligning to latest research.
