### More or Less

Tim Harford explains - and sometimes debunks - the numbers and statistics used in political debate, the news and everyday life. There is usually something on each episode that relates to math class, especially statistics (they are UK centric, however). I have highlighted a few particularly good ones for math class.- [New - Added Jun. 15th, 2018] - I liked this episode because there were some examples of problems with rating scales, the math of estimating how many wizards are in England in the Harry Potter books and picking apart the numbers in a study about the safety of home births. All of these, I thought, were really good at talking about how to analyze statistics critically. https://www.bbc.co.uk/programmes/p068w7c8
- [New - Added Jun. 15th, 2018] - Do you use "math" or "maths" it seems there is evidence why either can be acceptable. This segment starts at 17:43 and the jury may still be out, even after this. https://www.bbc.co.uk/programmes/p066x9fh
- I think when you are teaching statistics it is good to give students some strategies to help tell if a statistic is valid. On this episode, they do it on the back of a postcard. That is, there are five main points and they fit on the back of a postcard. http://www.bbc.co.uk/programmes/p05yfqph
- If you are dealing with metric prefixes or imperial metric conversions then this episode might be useful. It starts with the story of losing a Mars probe due to mixing up imperial and metric measurements and then ends with discussion of some of the larger metric prefixes. http://www.bbc.co.uk/programmes/p05jgh5y
- In this episode they look at the possible reason that albums are getting longer. The short answer is - more tracks means more potential clicks and higher chart placing. There is some interesting info about Spotify. I'm thinking you could have some conversations about rate using the information here about things like how many clicks is equated to one "purchase" - 1500 plays equates to one record sale. http://www.bbc.co.uk/programmes/p05mpr59
- The idea of a 100 or 500 year storm often is misleading to humans. In this episode they look at what that probability actually means. http://www.bbc.co.uk/programmes/p05f4qp9
- The Story of Average - Everything has to start somewhere. And even things that are so common have a beginning. In this case it's the story of where the idea of "average" came from. You can listen to this 10 min story on the origins of average by the BBC radio Show More or Less and wow your students with anecdotal info about mathematics. http://www.bbc.co.uk/programmes/p03qprk7
- The Math(s) of Spies and Terrorists - a really nice example of how 99% success rate in terrorist detection would result in a large amount of false positives in a country like th US with 300 million people. http://www.bbc.co.uk/programmes/b01snyk3
- Testing Public Opinion - Do you need to give real examples of how the way you ask questions on a survey can become biased by using Leading Questions then listen to this More or Less episode on how a poorly conducted survey in India likely gave unreliable results. This clip from the Yes Prime Minister that shows how by using leading questions you can get opposite results for the same question. http://www.bbc.co.uk/programmes/p04jz6sr
- Using order of operations. Listen to the More or Less podcast (starting at about the 11min mark) to hear the story behind the story and watch these two videos to see examples from the gameshow https://www.youtube.com/watch?v=pfa3MHLLSWI & https://www.youtube.com/watch?v=n8-mx3RSvOQ

### RadioLab

This is a well produced show that is mostly about Science (though lately it can be just about anything) and sometimes math shows up. They do a great job of storytelling- Numbers - here are three stories dealing with numbers. the first is about how innate the idea of number is, the second about one of my favour math theorems: Benford's Law and the third about a friendship that comes from Calculus. http://www.radiolab.org/story/91697-numbers/
- Math, Kurt Weill, Danica McKellar - Not all of the stories are about math but there are connections everywhere beyond the obvious with Danica McKellar. http://www.radiolab.org/story/162161-math-kurt-weill-danica-mckellar/
- Numbers - Alex Belos and others talk about favourite numbers and the power that they have. http://www.radiolab.org/story/love-numbers/
- Speed - lot's of stuff here that you can do with rates of change http://www.radiolab.org/story/267124-speed/

### Simon Singh's Numbers

Originally this was a five part series (Pi, Phi, i, 0 and infinity) and then it was expanded to a 10 then a 15 part series. It's more than a decade old but each short episode is about 12-15 minutes long and is well produced with many great facts about all kinds of math.http://www.bbc.co.uk/programmes/p00cl73s

### Whats the Point

This podcast was created by 538. That is Nate Silver's site about sports and politics (and entertainment) statistical analysis. On this show they do a great job of breaking apart stats and having experts explain what they mean. Most shows are good (though they are more like interview shows). but the ones below, I think, could be particularly useful when teaching stats. Although this Podcast is not in production anymore, you can still browse their archives.- Bad Incentives Are Blocking Better Science - Often one of the things that is glossed over is how much data analysis is used in science. Unfortunately students don't always get a rigorous treatment of data analysis. And in science classes it is kind of glossed over. That's too bad because it seems like there might be a crisis in the science world about misuse of data. http://fivethirtyeight.com/datalab/podcast-bad-incentives-are-blocking-better-science/
- The Secret To Tracking And Mapping Bears - This one is on collection of data on bears in the wild. I thought it was interesting how the mechanics are all done and how the data is used. http://fivethirtyeight.com/features/the-secret-to-tracking-and-mapping-bears/
- In the new book "Weapons of Math Destructions" @mathbabedotorg looks at the good and the bad of how algorithms affect our lives (it seems the book is about mostly the bad). Listen to this interview with her where she talks about some of the examples. http://fivethirtyeight.com/features/whos-accountable-when-an-algorithm-makes-a-bad-decision/
- Can You Taste The Algorithm In This Arugula? - I love when you can show the power of data in places you might not expect. In this case it's farming. For the average person, the amount of data that is used in current farming practices would be surprising but when I ask my farmer friends about it they say that using data is old news. None the less this is a great snapshot on how data is used in modern farming. http://fivethirtyeight.com/features/can-you-taste-the-algorithm-in-this-arugula/
- Rating Subjective Experiences Is Hard, But Fandango Is Really Bad At It - I really like this investigation into the online movie site Fandango. They do a very good job of breaking down how Fandango's ratings come in consistently higher than every other movie rating site. I especially like the bit about how they constantly rounded up to the nearest half point (so 4.1 would round to 4.5). Read the article for all the details or listen to the What's the Point podcast for the interview with the writer. It's a really good example of using data to tell a story. http://fivethirtyeight.com/features/fandango-movies-ratings/ http://fivethirtyeight.com/datalab/rating-subjective-experiences-is-hard-but-fandango-is-really-bad-at-it/

### A Brief History of Mathematics

In this 10 episode BBC series, Professor of Mathematics Marcus du Sautoy reveals the personalities behind the calculations and argues that mathematics is the driving force behind modern science. http://www.bbc.co.uk/programmes/b00srz5b/episodes/downloads### Planet Money

Planet Money is an NPR segment that has longer form shows on the economics of everything. They are well produced and often have things you can use in your standard math classes.- The Indicator - an offshoot podcast from Planet Money is called The Indicator which is a short look at a number in the news. This episode was 1994 which is the year graphing calculators were allowed to be used on the SATs and one of the things the podcast talks about is why the price of the TI-84 has essentially stayed unchanged since it's inception. https://www.npr.org/sections/money/2018/03/12/592962844/hurricane-joseph-the-calculator-that-time-forgot
- 10 11 51 52 62 18 - When ever I used to teach combinatorics I wouldn't miss talking about lotteries and specifically those like the 6/49 or the Powerball. Invariably we would talk about being able to buy all the possible combinations and what that would take. It was pretty quickly determined that you would need a huge effort or at least some sort of automation (much like Lazlo had if you have ever seen the movie Real Genius). Well, as it turns out, somebody has actually done this. They filled out and played every combination. http://www.npr.org/sections/money/2016/01/13/462982983/10-11-51-52-62-18
- The Experiment Experiment - This story from Planet Money is about the fact that many psychological studies are actually not repeatable. When talking about data management we often talk about bias and this episode talks about how bias could be why some of these studies are not repeatable. http://www.npr.org/sections/money/2016/01/15/463237871/episode-677-the-experiment-experiment
- Why A Pack Of Peanut Butter M&M's Weighs A Tiny Bit Less Than A Regular Pack - I like collecting real data in classes, and so I was thrilled with a reason to do so. That is, the mystery of why there are different weights of regular M&Ms vs Peanut Butter M&Ms per bag. The actual reason is a bit of a mystery. But collecting data about how many M&Ms are in each pack (or how much each pack weighs in reality) is a good way to talk about measures of central tendency, dot plots, and standard deviation. http://www.npr.org/blogs/money/2014/06/05/319084976/why-a-pack-of-peanut-butter-m-ms-weighs-a-tiny-bit-less-than-a-regular-pack
- What's Your Major? - Many have long said that mathematics was the way to a high paying job. Well now I guess we have the data to prove it. The US Census has always asked about income and level of schooling but in their most recent surveys they have also asked what people's majors were. The Planet Money people have a great podcast on the results (long and short versions below). And the survey says: Applied math (engineering, computer science etc) seems top the list. What's at the bottom? Psychology. A couple of things that resonated with me about this were a) that, in general, it didn't matter where you got your degree and b) it really had more to do with supply and demand. http://www.npr.org/blogs/money/2013/09/11/221417806/episode-485-whats-your-major
- At $17.5 Million A Year, LeBron James Is Underpaid - I am not completely sure how this could be used in a math class but I was fascinated by the connection of math and economics to show that LeBron James is actually severely underpaid at $17M per year. I am pretty sure you could tie this into statistics. http://www.npr.org/blogs/money/2013/01/25/170176590/at-17-5-million-a-year-lebron-james-is-underpaid

### Freakonomics Radio

Along the same lines as Planet Money, Freakonomics Radio takes the ideas of the book and continually applies them to all sorts of things. Sometimes they get into the math too.- "John Urschel of the Baltimore Ravens was the only player in the N.F.L. simultaneously getting a Ph.D. in math at M.I.T. But after a new study came out linking football to brain damage, he abruptly retired" - this story is probably a nice general interest topic spanning sports to math. http://freakonomics.com/podcast/brain-damage/
- How Do We Know What Really Works in Healthcare? - In data management it seems reasonable to talk about random controlled trials and why they are so important for research (especially medical research). With that being said, this is about that very thing. Certainly worth a listen, if only to gain insight we can pass on to our students. Personally, it's the kind of thing I would have students listen to and then have the discussion afterwards. http://freakonomics.com/2015/04/02/how-do-we-know-what-really-works-in-healthcare-a-new-freakonomics-radio-podcast/

### Science Friday

Science Friday is a weekly two hour radio show on all things science. That being said, they often have segments that relate to math.- Do you want to know how much garland you need for your conical shaped Christmas tree? How about how to win that Christmas match of Monopoly with your family? Listen to @FryRsquared on @SciFri as she talks about her (and @Mathistopheles) new book "
*The Indisputable Existence of Santa Claus (The mathematics of Christmas)*".

https://www.sciencefriday.com/segments/how-can-math-make-your-holidays-merrier/ - Interview: Randal Munroe - creator of XKCD and the book What if? https://www.sciencefriday.com/segments/randall-munroe-asks-what-if/
- Why Machines Discriminate—and How to Fix Them - In data management, one of the topics is bias in collecting and analyzing data. Here is a nice @SciFri podcast that starts out talking about computers that do the work of sifting through resumes and branches out into many different examples of bias seen with big data. Some good information for your students. http://www.sciencefriday.com/segments/why-machines-discriminate-and-how-to-fix-them/
- The Surprisingly Predictable Patterns of Random Choice - I'm a sucker for a good story on randomness. It's one of the things that many people don't understand. http://sciencefriday.com/segment/07/11/2014/the-surprisingly-predictable-patterns-of-random-choice.html
- Interview: Ed Frenkel - Russian Mathematician tells us why it's patriotic to do math http://sciencefriday.com/segment/07/04/2014/do-your-patriotic-duty-learn-math.html
- The Simpsons’ Secret? It’s Written by Math Geeks - Simon Singh's book on the math found in the Simpsons. http://www.sciencefriday.com/segment/12/06/2013/the-simpsons-secret-it-s-written-by-math-geeks.html
- Interview: Eugenia Cheng - Here this mathematician tells us how to bake Pi. http://www.sciencefriday.com/segment/05/08/2015/eugenia-cheng-how-to-bake-pi.html
- Spotlight on Pi Day - you can't get enough of Pi Day, I say https://sciencefriday.com/spotlights/pi-day/
- A Broadway Hit, With an Autistic Math Whiz at Its Center - The Curious Incident of the Dog in the Nighttime was first a book and now a broadway hit. But there is math all the way through it. http://www.sciencefriday.com/segment/01/09/2015/a-broadway-hit-with-an-autistic-math-whiz-at-its-center.html
- Interview: Danika McKellar - Actress and mathematician talks about her book "Girls Get Curves: Geometry Take Shape" https://www.sciencefriday.com/segments/actress-danica-mckellar-helps-girls-get-curves/

### The Math Guy

Keith Devlin is a Stanford Mathematician, but for almost 20 years he's had a side gig talking about mathematics on NPR's Weekend Edition. He does these in no regular interval but you can listen to almost all of the complete archive here:https://web.stanford.edu/~kdevlin/MathGuy.html

### NPR

There are often math related stories that appear elsewhere on NPR. Here are a few- The Teacher Who Believes Math Equals Love - here's an interview with teacher Sarah Hagen on the visual ways she uses in her math classes. It's part of this NPR story that is part of their series on the best 50 teachers in the US. She tweets at @mathequals love and her blog has all of her activities http://www.npr.org/blogs/ed/2015/03/09/376596585/the-teacher-who-believes-math-equals-love
- The Joy of X - here @stevenstrogatz talks about his book the Joy of X and how it came about from articles in The New York Times. http://www.npr.org/2013/08/02/207885870/steven-strogatz-the-joy-of-x
- Why Aren't More Girls Attracted To Physics? - though not directly related to math there is certainly a connection. http://www.npr.org/blogs/alltechconsidered/2013/08/09/210251404/why-arent-more-girls-attracted-to-physics
- On Marketplace Weekend they often have a segment called "By the Numbers" that usually appears about 12 -14 min into the episode. Check out some of them here. https://www.marketplace.org/shows/marketplace-weekend

### The Story Collider

The Story Collider is a podcast that is about people telling true stories about science (and some math). They are all recorded live at story slams and science festivals and are often quite interesting. Here are a few dealing with math in some way.- A couple of different stories related about math in honour of Pi Day. The first is a story of what inspired a reluctant mathematician Ken Ono (one of the producers of the movie "The Man Who Knew Infinity"). The second is a powerful story of racial and gender discrimination in the math community and elsewhere from @pwr2dppl. And if that is not enough, check out her thesis. It's written in a way that I have never seen a math/science thesis written. This quote from the prologue should pique your interest: "....try to read a math paper and think, “Oh my goodness what on earth does any of this mean why can’t they just say what they mean????”" https://www.storycollider.org/stories/2018/3/5/in-honor-of-pi-day-stories-about-math
- Find out about mathematician @lewlefton who is also a stand up comedian (with math jokes) and @TheMathGuru who talks about her first day as a student teacher. https://www.storycollider.org/stories/2018/1/5/math-problems-stories-about-math
- Adriana Salerno: A Different Kind of Problem - In these times of more awareness of mental illness comes a story of one mathematician's battle with depression http://storycollider.org/podcast/2015-09-25
- Alex Belos: Your Favourite Number - Alex is talking about how his quest to find the world's favourite number started (and how he himself blew off the idea of having a favourite number in the first place). I think that it is important for students to get these parts of mathematics so that they don't just see the drudgery of just doing problem after problem. Things like this bring out the humanity in math. http://storycollider.org/podcast/2015-01-26
- Ed Frenkel: The Test - Whether it was his book Love and Math, his Numberphile video Why People Hate Math, is LA Times OP Ed or his Science Friday interview and now with his Story Collider essay on math and bigotry and how love of math saved the day, Ed Frenkel has some good things to say. http://storycollider.org/podcast/2014-09-19
- Erika Engelhaupt: The Science of Speeding - Erika tells of how cognitive bias lead her boyfriend to jail. The story doesn't seem to be related to that at all as you are listening but it comes around at the end. Caution: there is one use of the f-word. http://storycollider.org/podcast/2014-08-22
- Jen Fitzgerald - Rocky the Mathlete - This one is a story from the perspective of a woman who, as a student, wrote math contests and was a "mathlete". Its kind of like The Karate Kid or Rocky but with math contests. Its kind of funny too (though there is some explicit language). http://storycollider.org/podcast/2012-08-26

### CBC

- Here @d_martin5 talks about assessing without percents (or grades at all). http://www.cbc.ca/radio/the180/promoting-failure-in-health-care-math-without-percentage-marks-and-should-alberta-join-the-u-s-1.2991087/math-without-marks-1.2991219
- The Math Wars continue to rage. And in light of the new "math focus" of the Ministry of Ed here in Ontario, here are @rachelinch & @alexoverwijk on the CBC talking about having a more problem solving approach to math is better than just drill and kill http://www.cbc.ca/player/play/2686398574
- So what happens if a parent with math anxiety helps their kids with their homework. Apparently a new study shows that those students will achieve 1/3 less knowledge in that year compared to not getting any help at all. http://www.cbc.ca/radio/quirks/quirks-quarks-for-sep-12-2015-1.3224539/children-catch-math-anxiety-from-parents-1.3224577

### 99% Invisible

99% Invisible is a show about architecture and design but often it has tangential topics. It is very well produced and even the episodes about math are quite interesting.- The Age of the Algorithm - another story about the book Weapons of Math Destruction from @mathbabedotorg http://99percentinvisible.org/episode/the-age-of-the-algorithm/
- A history of Average - and in this episode they use the history of calculating the average to tell the story about how we got to where we are today when it comes to customizing the size of things with stops along the way with fighter jet pilots and t-shirt sizes. http://99percentinvisible.org/episode/on-average/

### My Favourite Theorem

Hosted by mathematicians### 10-Minute Teacher

The 10-minute teacher podcast is a very practical podcast where teachers of all variety are interviewed and are giving tips of the trade in these small 10 minute nuggets. They are not all about math but I have highlighted some of the math related ones (though some of the others are pretty good too. They put out an episode every weekday (every day with a different theme) and @coolcatteacher does the interviewing. I only found out about it because I was suggested to them by someone as a potential guest. I'm glad I know about it now.- [New - Added Jun. 15th, 2018] - May 25th, 2018 - Five Principles fo the Modern Mathematics Classroom with @geraldaungst talking about these five topics in his book of the same name.
- [New - Added May 7th, 2018] - May 3, 2018 - How to Make Math Visual with @mathletepearce. Here Kyle talks about his latest passion with math in the idea of visualizing as much as he can. Based in research and the idea of "concreteness fading" he takes math concepts and visualizes them on his site http://mathisvisual.com/. Here about that and more on this episode.
- [New - Added May 7th, 2018] - May 2, 2018 - How Should we be Teaching Math in Classrooms Today with @MathDenisNJ. One of the biggest ideas that resonated with me here is the idea of engaging students in productive struggle. That is, when students are just struggling at the edge of their ability, they have the biggest gains.
- [New - Added May 7th, 2018] - Apr 19, 2018 - The Best PD for Math Teachers (and How to Use it) with me. I got to sit in with Vicky for one of these sessions and gave my elevator pitch on why Twitter has been the best math PD I have had. It has to do with the community of math teachers that share using the hashtags #MTBoS #ITeachMath and #Mathchat (among others).
- Mar 2, 2018 - 5 Ideas to level up elementary math with technology with Kelly Gary and certainly some of these are not just good for elementary math but for all math. For example, I love the idea of using a document camera to show student work.
- Feb 8, 2018 - Computational thinking and math for the elementary grades with @stevenpfloyd. Using coding to move math forward is certainly popular now but in reality it shows some practical uses of math for students and as he points out, it can be used to (secretly) get kids to do math well above their grade level
- Jan 10, 2018 - iPads for Masterful Math: Randomizing Formative Math Assessment with @Sean_Nank. There is no doubt that formative assessment done right is some of the best way to improve student achievement. Here he talks about some of the tools he's developed and, I think, most importantly the idea that if a student does poorly on an assessment they shouldn't have live with that grade but instead have opportunities to do better.
- Jul 26, 2017 - Inspiring Math Excellence in the Classroom with @PoShenLoh. Here he talks about the idea of challenging students at just the right level for them. Something that is so important because if it's too easy, students will be bored and if it's too hard then they will give up too soon.
- Jun. 8, 2017 - An Australian Math Classroom with iPads with
@trdavo. I think some of the most interesting stuff can be done with tablets. Something about the interface that makes it so inviting for students. He talks about many things but two of my favs are Explain Everything and Aurasma. - May 4th, 2017 - Helping Kids Who Hate Math Learn It with @ddmeyer. It's not surprising that Dan has been on this podcast. Here he talks about the structure he has tweaked and developed called the 3Act math task.
- Apr. 5th, 2017 - Felicia Casto’s Exceptional Elementary Math Classroom with @jfcasto28. Sometimes people who used to hate math are some of the best people to teach it. Reaching those students who love math is easy but connecting with those who don't, that's where the money is.
- Mar. 14, 2017 - Epic Ways to Celebrate Pi Day with @aap03102. I love some of the things they have done to celebrate Pi Day. My favourite is the image where each pixel is a student holding a digit of Pi.

### Miscellaneous Podcasts

This American Life: What's in a Number - This American Life is one of the big wigs of well produced radio shows and although there is very little math, this particular episode was all about one number and the good statistical methods that went into creating it. That number was the number of deaths caused by the Iraq War (as it was going on). It's longer but very well produced and, I think, is a must listen to for anyone teaching data management. https://www.thisamericanlife.org/radio-archives/episode/320/whats-in-a-number-%E2%80%94-2006-editionOn this episode of Note to Self they speak to @MonaChalabi who is the data editor for The Guardian who does some very cool stuff both in the publication and on her Instagram feed. She picks interesting data sets and creates interesting visualizations to represent them. Listening to a podcast doesn't do her work justice but listen at the link below and then and then check out her feed.

https://www.wnycstudios.org/story/data-mona-chalabi/

If you ever want to give students an example of the dangers of exponential growth then this story of a hacker who's "worm" inadvertently shut down the most popular site on the Internet (at the time) and did so because it grew exponentially. Listen to his story (starting at 1:19:17 ) on how he shut down MySpace (this was clearly a while ago) and how it eventually got him banned from using computers. @SamyKamkar is a hacker and he is being interviewed by venture capitalist and self experimenter @tferriss. It's a great (and long) podcast but the story in question starts at 1:19:17. http://fourhourworkweek.com/2015/05/02/samy-kamkar/

Have not heard of the Museum of Math (MoM)? Listen hear to find out why you should go to New York to visit it. http://www.wnyc.org/story/264330-down-and-dirty-at-the-museum-of-math/
