Thanks a bunch to @alonamit for leading today's SF math teacher circle. Explored a fascinating (and different) way to visualize functions. Spent time searching for fixed points, blinkers, & trinkers. Functions as simple as f(x)=-1/(1+x) were amazing!

"fear quadratics" - @SF_MTC speaker

iterating a quadratic lots of times to try to get back where you started....

[SF Math Teacher ◯ @SF_MTC]

@farrarscott @benorlin I'd call it an algorithm more than a game. But how are you defining a game?

Last weekend at the @SF_MTC playing with the Rubik's cube.

[Pedro MoralesAlmazan @p3d40]

Wonderful Saturday morning doing some math at the @SF_MTC . Also wonderful to say that I solve Rubik's cubes for a living.

First San Francisco Math Teacher Circle of the 2019-2020 school year! A big thanks to Pedro Morales-Almazán for facilitating a whole bunch of math using the Rubik's Cube. Also a big.rhabks to the 36 people who showed up.

@SF_MTC we are cutting stars!

Excited to have Elysée Wilson-Egolf fascilitating today's SF Teacher Math Circle at The Proof School. She'll be discussing a very surprising mathematical result involving scissors. Hope to see you there!

Who knew gerrymandering was so hard? At @SF_MTC hosted by @Desmos today

[Paul Zeitz @PaulAZeitz]

Big turnout at Desmos for San Francisco Math Teachers’ Circle. Bree Murray is leading us in the very timely topic of the Geometry of Gerrymandering! #batmath

[SF Math Teacher ◯ @SF_MTC]

@zimmerdiamonds @rdkpickle @btwnthenumbers Next SF Math Teacher Circle is this Saturday at @desmos hq, led by @btwnthenumbers on the topic "Geometry of Gerrymandering." Session runs from 9:30-12. While you won't get to vote on the types of bagels, strength of the coffee, or what we order for lunch, we hope you can join!

Fingers that can see whether cards are up or down. It's mathemagical.

[SF Math Teacher ◯ @SF_MTC]

First San Francisco Math Teacher Circle of the year! Thanks to @PaulAZeitz for facilitating, and thanks for the Proof School for hosting. Raise your hand if you're excited to do some math.
