The Build Math Minds Podcast

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...

Are you exhausting yourself trying to make everything "equal" in your math instruction or math coaching? In this video, I'm sharing why balance in teaching isn't about equality - it's about creating a beautiful structure that meets the needs of those you are working with. Let's rethink what balance really means for elementary math teachers and coaches. Get any resources/links mentioned in this epi...

When your students ask "When will I ever use this?"—especially with AI doing calculations faster than any of us—how do you answer? In this episode, I share a conversation that just validated how I think about the purpose of teaching math.    Spoiler: It's not about long division. It's about building thinkers, not calculators.    You'll hear the difference between students who DO math versus studen...

Are your students still counting on their fingers for 6×4? Transform how you teach multiplication facts with this game-changing approach to subitizing! In this episode, you'll discover how to move beyond the exhausting "times tables treadmill" that forces students to memorize 100 disconnected facts. Instead, learn how subitizing—the ability to instantly recognize quantities without counting—can he...

Discover how subitizing—the ability to instantly recognize quantities without counting—can transform your fraction instruction! While you may already use subitizing with your younger students, this episode reveals why it's equally powerful for upper elementary learners working with fractions. You'll learn what subitizing with fractions actually looks like and why keeping quantities small makes all...

You know that building number sense is crucial—but finding time for one more thing feels impossible. In this episode, discover how investing time in foundational number sense concepts actually saves you time in the long run. Learn two practical strategies for fitting this essential work into your already-packed day without adding anything extra: the 1% Better Approach and the Replace, Don't Add St...

Are you doing all the "right" math activities—Number Talks, Number Strings, Quick Images—but still not seeing the progress you expected? In this episode, you'll discover why having great activities isn't enough, and what actually builds real number sense with your students. You'll learn the critical difference between facilitating activities to collect answers versus facilitating them to develop d...

Are you overwhelmed thinking about trying to add in number sense activities into your already jam-packed day? In this game-changing episode, learn how to transform your math instruction by integrating number sense concepts into ONE quick activity.  The 'unspoken rule' of teaching math has been to keep each math skill in separate boxes that we teach in isolation.  Teaching in this way is one of the...

In this second episode of the math fluency series, we explore the four essential number relationships that help students move beyond counting and develop true mathematical thinking. Learn about spatial relationships, one/two more or less, benchmarks of 5 and 10, and part-part-whole thinking—and discover how these relationships evolve from PreK through fifth grade. We'll look at why students get st...

In this episode, I'm kicking off a series on building math fluency by diving into what I wish I had known when I first started teaching—the critical foundations students need BEFORE we ever ask them to add, subtract, multiply, or divide. Many students can DO the math, but they don't truly UNDERSTAND it. And the problem isn't that they need more practice—they're missing something much more fundamen...
