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!”

“The resources provided were very helpful and easily applicable! There were several opportunities for participation and conversation that were non-threatening and reflective!”

This is Part 2 of a mini-series on a rubric masterclass. Be sure to check out the Intro post and subsequent posts. We’ve spent the last 5+ years in the math education community advocating for teachers and students to have a growth mindset. We tell students that they can and, in fact, do continue to…

This is Part 1 of a mini-series on rubrics. Be sure to check out the Intro post and subsequent posts. It took me a while to figure out the whole rubric game. I’ll admit, I was relatively anti-rubric in the middle of my career. Maybe that’s because I wasn’t shown how to construct one. Maybe…

This blog post introduces a new mini-series from Emergent Math: A Rubric Masterclass.

The tl;dr version: I’m seeking secondary teachers interested in designing and implementing a portfolio system of assessment in their class. Interest form link below. I’m currently wrapping…

Schools and teachers have no incentives to foster a nurturing atmosphere for student teachers. Unless the school expects to hire the student teacher, there’s no inherent reason for a school to particularly care whether or not the student teacher makes education a lifelong passion or if they burn out and never even enter the profession.…

The 2021 NFL Draft is next week. And, as is often the case, quarterbacks are expected to be drafted highly and dominate the narrative. In a game with 22 starters (plus kickers and punters!) quarterbacks routinely dominate the top selections of the NFL Draft. And it makes sense. If you land a quality quarterback, you’re…

“Nathan For You” is a docu-series on Comedy Central (episodes available on Hulu) in which comedian and Canadian good-grades-getter Nathan Fielder “fixes” business by suggesting out of the box ideas to bring in new customers. These ideas includes amping up the scariness of a haunted house by telling the attendees they’ve contracted a fatal airborne…
