A friend's story leads Pete and Noah to dive into the high-stakes world of poker to settle a debate: does a flush really beat a straight? Using the tools of combinatorics and probability, our hosts break down the math behind five-card hands and explore how the hierarchy of the game is built upon the frequency of outcomes.  Ante up…  the next hand is about to begin!

In this episode, veteran educator Sheila Robitaille joins Pete and Noah to discuss World Math Day, a global competition for students ages 5 to 18 that promotes mathematical fluency through 60-second "live Mathletics" games. The conversation highlights the 2026 theme, "United by Numbers," exploring how gamification can foster a growth mindset and make math fun and engaging for kids at all levels of math proficiency.

If we asked all of our listeners to look up the current population of their hometown and email us just the first digit of that number, what do you expect we'd find?  Would the digits be evenly distributed, or would some be more common than others?  In this episode, we look at Benford's Law, and learn some surprising truths about the distribution of numbers in natural data sets.   Leave us a voice message Find us on Twitter Send us an email Questions Answered in the Episode: • What is Benford's Law and how does it predict the frequency of leading digits in data sets? • Why do natural data sets like city populations and surface areas often follow a logarithmic distribution of first digits?

Hey there Math Club.  Our most recent episode, Math Club Junior:  It's a Zoo Out There, was our second special episode made specifically for kids.  When Noah was planning how he wanted to use the episode with his own third grade class, he knew that some visuals would come in handy, so he created a slide deck with images to go along with each problem that the students will have to solve.   If you'd like to use this resource along with the audio, you can find it by going to: https://bit.ly/mcj_zoo We hope you find these images to be fun and helpful, and we'll see you next time!  

In this long-awaited followup to our popular Math Club Junior episode, Pete and Noah are back with Mrs. Morrison's class, as chaperones on a field trip to the local zoo. Listen in as our group of Junior Zookeepers meet a whole new cast of zany characters, and once again learn that math is everywhere if you just look around. And just like last time, this story is full of interesting math challenges for listeners in the upper elementary grades to enjoy and solve.   • A slide deck with visuals to go along with each problem from the story   Leave us a voice message Find us on Twitter Send us an email  

A family visit to the Netherlands introduces Pete to the idea of average speed zones, which illustrate a particularly interesting mathematical theorem.  Join our hosts as they really go off on a tangent about the mean value theorem, and how it just might get you a speeding ticket.
