Gladys Mae West obituary: mathematician who pioneered GPS technology
She made key contributions to US cold-war science despite facing huge barriers as a Black woman.
No joke: I got angry hate mail today for writing an obituary of a Black woman scientistβbecause the person felt she did didnβt deserve the recognition.
Which just makes me want to share it again: www.nature.com/articles/d41...

I finally got @triangleman.bsky.socialβs How Did you Count? in front of some 2nd graders today!
Their work reminded me that math should be about honoring thinking, engaging with otherβs ideas, and trusting the math that lives in our studentsβ heads.

Book cover for How Did You Count? There is a sideways diamond of shiny plastic spheres carefully arranged on a wood floor. The left "half" of the diamond is a triangle with base five, made of light blue spheres. The larger, right "half" is a triangle with base six, made of red spheres.
Good morning!
Number one way in the coming weeks to support the work that brought you Which One Doesn't Belong?, Tiling Turtles, Math On-A-Stick, and the Hierarchy of Hexagons is this:
Pop into your fave bookstore or library to ask for How Did You Count? ISBN: 978-1032898353

Oh hey, will you be in Seattle for the NCTM Regional next month? A @mathhappens.bsky.social colleague and I will be there, together with SUMM, in a decompression/play space outside the exhibit hall.
Come play and say hi (and maybe take home a hexagon challenge frame for your classroom?)
