Description: Blog by a math teacher who believes "... that learning to use mathematics changes people's lives in profound and valuable ways," and describes himself as "obsessed with making that happen for people. I am convinced that recent advancements in technology make it possible to drastically change the way we engage with mathematics, including the way we learn it and teach it...." Posts, which date back to March, 2017, have included "A New Math Competition Idea"; "Introducing the Dot-Dot Simulation"; "Mathematics is a Tool For Storytelling"; "Experiencing Michael Fenton's Rectangle World"; "Teaching the Meaning of Mathematics"; "Understanding Lillian"; "Graphs are Overrated. Simulations are the Future"; "How to Change the World with Mathematics"; and "On Structuring our Community to Increase Belonging." O'Malley's library of simulations draw on Wolfram|Alpha and Geogebra; his resources include spinner math, for creating rotations using mathematics; and smoosh math, lessons for understanding stretching and compressing linear functions.
