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.
