Ep 68 - Mathematical Knowledge for Teaching

Ep 73 - Kevin Dykema is rethinking productive struggle

Kevin Dykema invites us to rethink productive struggle as more than a math education buzzword. Instead of rescuing students with steps and answers, he shows how teachers can create the conditions for students to reason, grapple, and make sense of mathematics. In this episode, Kevin shares practical ways to make struggle productive, including building positive math identity, creating a supportive classroom community, planning better tasks, anticipating student thinking, and asking questions that rescue thinking instead of answers. You’ll hear classroom-ready examples involving mental math, integers, fractions, exponents, quadratics, and task design. Kevin also reminds us that reflection matters, both for students and teachers, because struggle becomes powerful when learners can see how far their thinking has come.

Ep 72 - Nolan Fossum is rethinking instruction through cartoon math

Nolan Fossum invites us into the learner’s seat by experiencing math in an unfamiliar way. Using a “cartoon base-10” system, he creates moments of productive struggle that mirror what many students feel when they don’t yet have fluency. In this episode, Nolan explores how counting, deriving, and reasoning through models like ten frames, number lines, and base-10 blocks can build deep understanding. Rather than relying on memorized facts, he highlights how students can develop flexible strategies by connecting ideas and using what they know. You’ll hear how this experience shifts perspective on student struggle, the importance of manipulatives, and why slowing down to build conceptual understanding matters. Nolan also connects this work to mathematical practices, student engagement, and the role of challenge in learning. If you’ve ever wondered what it truly feels like to not “just know” the math, this episode offers a powerful reminder and practical insights for supporting all learners.

Ep 71 - Screens screens everywhere screens

Scott and Duane get together to chat about math, but Duane gets grumpy and jumps up on his soap box to complain about schools using too much EdTech throughout the day. We know students go home and endlessly scroll on their phones, so schools should be very picky and choosy about whether to add to the screen time at school. Also, the EdTech we use at school should augment the teacher rather than replace the teacher. Give this episode a listen and leave a comment.

Ep 70 - Mark Alcorn on goals, agency, and meaningful mathematics

In this episode, Mark Alcorn (educator, coach, and founder of the Sum of It All podcast) invites us to rethink something deceptively simple: goals in math classrooms. Rather than treating goals as compliance-driven statements or posted objectives, Mark challenges us to see them as powerful drivers of student thinking, engagement, and agency. Mark explores how, even when we don’t name goals explicitly, they still exist and shape classroom experiences. He unpacks common barriers (“bad warm-up bands”) that keep goals from being meaningful, including performance-focused language, overly broad standards, and goals written only for teachers.  CONTACT / RESOURCES Mark Alcorn mark@mark4math.com [mark@mark4math.com] Instagram: mark4math Linkedin.com/in/mark4math [http://linkedin.com/in/mark4math] LEARN with the California Mathematics Council… ✚  Join us in our monthly Inspiring Math Minds webinars and get on our mailing list to be notified:      https://www.cmcmath.org/cmc-central/virtual-learning-series [https://www.cmcmath.org/cmc-central/virtual-learning-series]  ✚  Visit the California Math Council website:      https://www.cmcmath.org/ [https://www.cmcmath.org/]  ✚  Become a member of the California Math Council:      https://camc.memberclicks.net/member-info-join-renew [https://camc.memberclicks.net/member-info-join-renew]  SUBSCRIBE! ✚  YouTube (video & audio):      https://www.youtube.com/playlist?list=PLvolZqLMhJmlKZXVW-HMWHmGsXXaeH09f [https://www.youtube.com/playlist?list=PLvolZqLMhJmlKZXVW-HMWHmGsXXaeH09f]  ✚  Spotify (video & audio):        https://open.spotify.com/show/7A17FvtyV8FiFJ0SWoTiQm?si=44d81611497e4c7a [https://open.spotify.com/show/7A17FvtyV8FiFJ0SWoTiQm?si=44d81611497e4c7a]  ✚  Apple Podcast (audio only):        https://podcasts.apple.com/us/podcast/math-on-the-rocks/id1728772089 [https://podcasts.apple.com/us/podcast/math-on-the-rocks/id1728772089]

Ep 69 - Talking about MKT. The Sweet Sauce.

We all got together to chat some more about mathematical knowledge for teaching (MKT) and why it is so important for teachers to have it. Who is responsible for supporting teachers in their development of MKT? When is it supposed to happen? We have more questions than answers in this episode. We know that answer is in part…DOING MATH TOGETHER. When teachers do math together, this is when we develop our MKT.
