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.

“THANK YOU for helping to make teaching math more relevant and helping me feel at ease because I still suck at math but will always continue to learn all I can so as to reach out to more students to help them love math too!”
— Secondary Teacher, Idaho

Education journals are calling for papers on AI, but educators have barely even had access to it. So what kind of research on AI are we going to see in 2024?
It’s important as seasoned Math teachers we remember what it’s like to experience new content. Modern tabletop games might be the best way to create those experiences.

Being new to the institution, I mostly hewed to the standards and progressions and textbooks from prior iterations of the course taught by more tenured faculty.

It was only a few years ago, but there was mass outrage in a way that seems unthinkable today. Most notably, the National Basketball Association…
