Geoff’s Longform Math Education Miniseries
I’ve done a lot of longform blogging. I call them “mini-series” where I do a deep dive into a particular aspect of math instruction.
Necessary Conditions
My book about math instruction and accompanying card sets for professional development use.
Feedback from Geoff’s Professional Development

Emergent Math Winter Mini-Series: How (not) to get your PhD
(Usually I reserve my longform blogging projects or other math projects on this website for the Summer.

‘Necessary Conditions’ Five Years Later

Reconceptualizing “more math” for pre- and in-service teachers
I am rereading Liping Ma’s Knowing and Teaching Elementary Mathematics for a class. It’s an exceptional book; I’d put it on the Mount Rushmore of books about math education (that might be a post for another day).

No pushback: So I guess education has given up
In 2019, North Carolina attempted to push through a bill that would force trans individuals to use the bathroom of their sex assigned at birth, rather than their current gender.
