Hi Folks,
The San Francisco Math Teachers‘ Circle will have its second session of year 3, on Saturday, October 27. We will meet at Desmos, which is located at 1488 Howard St between 10th and 11th (lots of metered street parking).  Our session will start at 930AM, with lunch arriving about noon.
The facilitator will be Breedeen Murray, and the timely topic, just in time for Election Day, will be The Geometry of Gerrymandering:
With the preponderance of district- and precinct-level data, gerrymandering has gotten more and more sophisticated over the past several decades. Gone are the classic “Goofy kicking Donald Duck” style district maps–their “ugliness” clearly highlighting the fact that something sketchy was afoot–instead, a perfectly reasonable-looking map can disguise a multitude of partisan sins. How then can we determine whether gerrymandering has taken place? The answer lies in mathematics. Two approaches can be taken: a geometric approach, where we look at the compactness of districts, and a data-analysis one, where we look at measures such as the “efficiency gap” and the “extreme outlier” to draw conclusions about the fairness of an election. In this session we’ll explore a sampling of these ideas and point you to some places where you can learn more.
Please RSVP with this link, and feel free to forward this invitation to others who might be interested.
The SFMTC is open to all local math educators, and our mission is to provide exciting and enriching “escape the textbook” activities.
We hope to see you on October 27!
