The Build Math Minds Podcast

Christina Tondevold

The Build Math Minds podcast is for my fellow Recovering Traditionalists out there. If you don't know whether or not you are a Recovering Traditionalist, here's how I define us. We are math educators who used to teach math the traditional way. Flip lesson by lesson in the textbook, directly teaching step-by-step how to solve math problems. But now, we are working to change that to a style of teaching math that is fun and meets our students where they are at, not just teaching what comes next in the textbook. We want to encourage our students to be thinkers, problem solvers, and lovers of mathematics..we are wanting to build our students math minds and not just create calculators. If that is you, then this podcast is for you.

    The Science of Math

    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's challenge the common practice of taking research from reading instruction and automatically applying it to mathematics without questioning whether it actually fits. Just because something works for teaching reading doesn't mean it will work for teaching math—our brains process these subjects differently. Second, I challenge you to really take a look at the good and bad of what research suggests we do through the lens of timed tests. While research shows timed tests can increase fact retention, I ask the important follow-up questions: What about student anxiety? What about their enjoyment of math? I break down the actual benefits of timed tests (goal-setting, measuring progress, feeling achievement) and challenge listeners to find ways to get those benefits without the negative side effects. I'll leave you with two key questions to ask whenever you hear about "what the science says": Was this research actually done with mathematics, or are we borrowing from another field? If the research looks good but feels wrong, can you get the benefits without the downsides?

    Seeing Multiplication - How Subitizing Builds Fact Fluency Through Relationships

    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 help your students see multiplication as beautiful, connected relationships. You'll learn: Why traditional fact memorization fails (and what works better) The 4 Types of Multiplication Facts that create a foundation for all others  How to use ten frames and visual arrays to make multiplication facts "subitizable" Three classroom-ready strategies you can implement tomorrow How to help students see that facts, like 7×6, aren't random facts to memorize, but are connected to facts they already know (like 5×6 or 7×5) This episode walks you through the visual progression from scattered groups to organized arrays, showing you exactly how to use color-coding and strategic groupings to make even challenging facts like 8×7 accessible through relationships. You'll also see how all eight foundational number sense concepts work together to build true multiplicative thinking. Stop asking your students to memorize 100 isolated facts. Start helping them see the patterns, understand the relationships, and actually enjoy learning multiplication. Your students (and their fluency) will thank you!
