The Math Club

All you have to do is look around to see that the world is changing very rapidly. But the course sequence of math education in American schools has changed little since the 1950s. In this episode, Pete and Noah welcome Ted Dintersmith, author of the book Aftermath, for a lively discussion about which math skills and concepts can best prepare today's students for the world of tomorrow.

Hey there, Math Club. We have some exciting news to share. Noah has teamed up with yet another Pete to bring you yet another show! A Novel Approach is dedicated to creating novel length stories, produced as immersive audio productions. The first book is called "The End of Secrets", and it explores what happens when the ancient world of vampires collides with the modern world of AI. In each pair of new episodes, you'll get to hear a new chapter of the book, and then a short discussion about how that chapter was put together. We're including the first chapter here. If you like it and want more, you can find it on Apple Podcasts, or in whatever podcast app you like to use. Just search for "A Novel Approach", or use our RSS feed

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.

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
