The Build Math Minds Podcast

Most math "group work" is students working side by side, then comparing answers.  That's not collaboration, that's what Amy Lucenta and Grace Kelemanik call parallel problem solving. In this video, I'm sharing one microroutine from their book MicroRoutines called "Getting on the Same Page." It fixes this by changing just one thing: how many pieces of paper are on the table. When partners share ONE...

Sold a Story Season 2 has us all talking about Project Follow Through, one of the largest education studies ever done. But after listening, I came away with more questions than answers. Even the program that "won" had schools where it worked and schools where it didn't. In this episode, I share three things I keep pondering: When a school "uses" a program, how many classrooms are actually teaching...

Have you ever asked a student "How'd you get that?" and gotten a shrug, or "I just knew"? What you ask NEXT decides whether you actually get them to explain their thinking. In this episode, I break down two patterns of questioning from the NCTM article Questioning Our Patterns of Questioning by Beth Herbel-Eisenmann and M. Lynn Breyfogle: funneling and focusing. Funneling feels like good teaching,...

Have you ever had a student add 3/4 + 3/4 and get 6/8? We usually call that a procedure problem, but it's not. It's a WHOLE problem. In this video I show you how the "part of a set" fraction visual quietly changes the whole and makes 6/8 feel completely logical to kids. Then I share why part of a whole and number lines need to come first, how I use fraction subitizing to keep kids focused on the w...

Have you ever had a student who looks lost before they've even started a problem? Or a kid who can do the steps but can't see the pattern that makes them work? I sat down with Becky Lord of LordMath.com to talk about the five cognitive areas that affect how our students learn math: working memory, processing speed, verbal comprehension, visual processing, and fluid reasoning. Becky explains what e...

Duolingo rolled out full math courses this year.  I spent 50+ days, spending time in number sense, addition/subtraction, multiplication, fractions, and even went into 11th grade Algebra & Graphs….until I couldn't take it anymore.   Zak and Mike from Flynn Education have also been using it and the three of us recently sat down to talk about it. We broke down what's good, what's bad, and what worrie...

I got to sit down with Steve Wyborney, the brain behind Splat!, Esti-Mysteries, the Estimation Clipboard, and so many other tools I know you've used in your classroom.  In this session from Day 3 of the FROM Memorization TO Thinking Summit, Steve takes me back to where it all started: an idea for building estimation jars that flopped. We talk about what estimation really is, why he thinks the seco...

I used to think assessment meant finding what my students didn't know - the wrong answers, the gaps, the "not yet."  Dr. Nicki Newton flips that in this session from the FROM Memorization TO Thinking Summit. Her thoughts: assessment shouldn't be about catching what kids don't know. It's about listening for what they do know.  In this episode, she shares the story of a 2nd grader who taught her mor...

A look at math intervention that reframes it from "filling gaps" to "building a staircase." Juliana Tapper explains why just-in-time intervention (keeping grade-level content as the destination) outperforms the just-in-case approach most schools default to.  And why teacher expectations, not the program you pick, drives the difference.  This episode is the full length conversation I had with Julia...

The summit was originally envisioned to help educators move students from memorization to thinking, but the focus shifted to a more important goal: stopping the educational pendulum from swinging drastically between the two extremes. The initial movement toward exploratory thinking emerged as a backlash against rigid drill-and-practice memorization and single-procedure methods that were not workin...

When's the last time you asked someone to just show you how to do something, instead of figuring it out yourself? Now flip it: how often do you ask students to just go figure something out on their own? In this episode, Christina digs into a pattern that surfaced again and again while interviewing presenters for the upcoming Math Summit: we preach productive struggle for kids, but rarely practice...

Picture two teachers: one runs "I do, we do, you do" with a focus on math procedures. The other hands kids an open problem and steps back entirely. Both are stuck at opposite ends of the same pendulum swing. In this episode, I unpack a theme that kept surfacing across my interviews for the upcoming From Memorization to Thinking summit: math ed keeps overcorrecting. We ditched rote memorization for...

In this episode, I'm making a confession: there's a free, research-backed guide for helping struggling math students that I haven't done a good job of telling you about and I've found that most educators have never even heard of. It's the 2021 Institute of Education Sciences and What Works Clearinghouse practice guide, Assisting Students Struggling with Mathematics, and all six of its recommendati...

After 26 years, Susan Jo Russell's three-part definition of math fluency - accuracy, efficiency, and flexibility - is finally making its way into state math standards. In this episode, I'm celebrating this long-overdue shift, highlighting recent updates in Washington State and Iowa that now explicitly include flexibility alongside accuracy and efficiency in their fluency standards. Using a relatab...

After 10 years of running the Virtual Math Summit, here's what I've learned: what matters isn't the objective you planned. It's the residue - what actually gets left behind once it's over.  My objective in creating the summit all those years ago was to help you build your math mind…but the residue isn't always something about the mathematics. Last weekend we wrapped up the 10th annual Virtual Math...

Most educators who want math to be taught conceptually are the only one in their building trying to do it. They go to a workshop, get excited, and come back on Monday to a team still teaching algorithms and admin who wants scores to go up. The excitement fades and not because the idea was wrong, but because doing hard things alone is exhausting. In this episode, the last one before the 10th annual...

The CRA Model isn't a linear path. It's a Venn diagram. And when you hit the Sweet Spot, where concrete, representational, and abstract all overlap, that's when the magic happens. In this episode, I'm revisiting one of my favorite topics and showing you why hands-on and visual learning matter MORE than ever for upper elementary students. Two examples of the CRA Sweet Spot: Early elementary: 7 + 8...

Building Thinking Classrooms is powerful—but when teachers try to implement all 14 practices at once, it falls apart. In this episode, I share a better approach for math coaches: focus on ONE practice based on what your teachers actually want to improve. I walk through why the "all at once" approach backfires, how to choose which practice to start with, and how to build incrementally so changes ac...

In this episode I'm saying something that might surprise you: Flexibility alone isn't enough for math fluency. I know, I know. I literally have courses called The Flexibility Formula. I talk about flexibility ALL THE TIME. But here's the thing: We've swung the pendulum too far. The problem: For years, we taught fluency through drill type worksheets, timed tests, and memorization. That had major do...

Over the past few weeks, I've had AI generate 13 math lessons.  Teachers ARE using AI to generate lessons—whether we like it or not. So instead of pretending that's not happening, I decided to put AI to the test. Can it actually create good math lessons? The short answer? Not really. But the insights I gained from evaluating those 13 AI-generated lessons? Those apply to ANY math lesson—AI-generate...

 Teachers are overwhelmed, students are struggling, and the strategies that worked pre-pandemic aren't working anymore. In this episode, I tackle one of the biggest mindset barriers happening right now: "They should already know this." Yeah, they should. But they don't. So now what? I'm giving you three practical coaching strategies to help teachers shift from "they should know this" (which leads...

In this episode, we tackle a hot topic in education: the Science of Math. Inspired by a podcast about women's health and a meeting with state math supervisors, I'm exploring two critical questions educators need to ask when applying research to their math instruction. First, is a powerful parallel I had when I heard: "Women are not small men" and that helped me think that math is not reading.  Let...

Do your students complete their math practice but forget everything by next week? There's a reason this happens—and a simple fix. Australian educator Michaela Epstein reveals why most practice only goes one direction (question → answer) and shares sorting & matching tasks that build real understanding. Learn how to add one metacognitive step that transforms mindless practice into flexible thinking...
