Learning Through the Ranks: A Graduate Student Blog is hosted on the MAA's Math Values blog and edited by Jasmine Camero. My posts are linked below.
From 2019 to 2021, the AMS Graduate Student Blog featured writing by and for graduate students. It is now retired, but you can still view the archived version. I was a writer for this blog in Fall 2021; you can find my posts linked below.
This series of blog post style notes grew out of a DRP on sabermetrics, the mathematics of baseball. These are aimed at a broad audience, but assume some familiarity with the game of baseball.
As an instructor for Emory Math Circle, I have developed many lessons aimed at engaging middle and high school students in mathematics exploration. Below are some of my favorites.
You are welcome to adapt and use these, though I ask that you attribute credit to me in any written materials you share (e.g. if you write an adapted lesson plan, please include "adapted from a lesson on LESSON_TOPIC written by Christopher Keyes and available at THIS_WEBSITE").
