Episode 204 -Timed Math Activities…Good or Bad? Sep 14, 2025

Show notes

Are timed math activities helping or harming our elementary students? This controversial topic divides educators, but the research tells a clear story when we dig deeper.

In this episode, we explore evidence-based strategies for using timed activities to build math fluency without creating anxiety or trauma. Drawing from the What Works Clearinghouse's analysis of 27 studies involving over 4,300 students, we discover that the problem isn't timed activities themselves—it's how they've been implemented.

You'll learn the five essential steps for effective timed math practice: identifying already-learned topics, choosing engaging activities, ensuring students have efficient strategies, tracking meaningful progress, and providing immediate feedback. We move beyond traditional worksheets and timers to explore alternatives like number talks, mental math relays, and "beat your own score" games.

This episode directly addresses real teacher questions about timed facts assessments and students who struggle with computation speed on standardized tests. We tackle the balance between building number sense and developing computational fluency, offering practical solutions for both classroom instruction and assessment preparation.

Whether you're a classroom teacher questioning your current math fluency practices or a math coach supporting teachers through this debate, this episode provides research-backed strategies you can implement immediately.

Episode 203 - Number Sense with Christina Tondevold and Mona Iehl May 25, 2025

Show notes

In this cross-posted episode from Math Chat, host Mona Iehl interviews Christina Tondevold about developing number sense in elementary students. Christina shares her journey from a "procedural" math student to becoming a math coach and founder of Build Math Minds.

The conversation explores the eight components of number sense: four early numeracy concepts (subitizing, verbal counting, object counting, and cardinality) and four number relationships (spatial relationships, one/two more or less, benchmarks of 5 and 10, and part-part-whole). Christina explains how these concepts help move students beyond counting to more efficient math strategies.

Practical classroom strategies discussed include using sticky notes to assess students' visual number understanding, implementing subitizing activities, and strategically choosing numbers in word problems to reinforce key number relationships. Both educators emphasize the importance of allowing students to solve problems in ways that make sense to them, rather than forcing procedural approaches.

This episode provides valuable insights for teachers looking to build true mathematical understanding rather than just procedural knowledge in their students.

Episode 200 - The Three Essential Math Experiences: Number Routines, Word Problems, and Games May 04, 2025

Show notes

In this milestone 200th episode of The Build Math Minds Podcast, I share the three essential math experiences every classroom needs: Number Routines, Word Problems, and Games. Drawing from research-backed practices in the IES/WWC guides, I explain why these activities are crucial for developing conceptual understanding, procedural fluency, and application in mathematics. Learn how Number Routines make implicit math concepts explicit, how Word Problems should help students understand mathematical structures beyond keywords, and how Games provide engaging practice that builds fluency. To celebrate this 200th episode milestone, I'm offering a free Google file with examples of all three experiences that you can download at BuildMathMinds.com/200. After 200 episodes, these core principles remain unchanged - Routines, Word Problems, and Games help Build Math Minds!

Episode 199 - The Many Ways to Show Numbers with Fingers Apr 27, 2025

Show notes

In this episode, I explore the fascinating world of finger use in math and specifically how we represent numbers differently. After noticing that Dan Finkel and I show the number 3 with completely different finger configurations, I dive into why these variations matter for children's mathematical understanding. Through personal stories about my own children's attempts to show the number 5, I highlight how fixed representations can limit children's number sense. Join me to discover why showing quantities in multiple ways—whether using fingers, ten frames, or rekenreks—helps develop deeper mathematical thinking and flexibility. A must-listen for teachers and parents wanting to build stronger number foundations with young learners.

Episode 198 - Tips for Using Games to Build Math Minds with Dan Finkel Apr 20, 2025

Show notes

In this episode, Christina Tondevold welcomes special guest Dan Finkel, founder of Math for Love and creator of popular games like Prime Climb and Tiny Polka Dot. Dan shares his three essential principles for effectively implementing mathematical games in the classroom: games should involve meaningful choices, math should be the engine driving the gameplay, and games should be simple to learn and quick to play. Through personal stories and classroom examples, Dan and Christina explore how games transform math from a dreaded chore into an engaging learning experience. The episode concludes with a demonstration of the "31 Game," a simple yet strategic counting game that exemplifies how mathematical play can build number sense, encourage strategic thinking, and create a classroom culture where students aren't afraid to show what they don't know. Perfect for educators looking to reinvigorate their math instruction between standardized testing periods!

Episode 197 - Upleveling Missing Part Games Apr 13, 2025

Show notes

In this final episode of our three-part series on upleveling missing part activities, I share ways to transform two popular math games: Salute and Number Sandwiches. Learn how to modify these traditional games to help your students build a deeper understanding of number relationships through missing part problems. These upleveled versions create opportunities for students to work with equivalent expressions while maintaining the fun and engagement of game-based learning. Perfect for elementary math teachers looking to enhance their daily math lessons with games that challenge students to think more deeply about mathematical relationships.

Episode 196 - Repackaging Style Word Problems: Transforming Missing Part Word Problems Apr 06, 2025

Show notes

In this second installment of our three-part series on Missing Part Activities, we explore 'repackaging tasks' - a powerful approach to traditional missing part word problems. While educators are familiar with finding unknown parts in word problems like "Christina has $12, she spends some now she has $7. How much did she spend?", repackaging tasks push mathematical thinking further by having students redistribute quantities across equivalent expressions. Through practical examples in both multiplication and addition contexts, I demonstrate how these problems help students develop a deeper understanding of equality, number properties, and flexible thinking strategies. Learn how incorporating these enhanced word problems alongside your regular curriculum builds stronger mathematical minds.
