Math Links for Week Ending Dec. 21st, 2018

Currently I am the president of the OAME (Ontario Association for Mathematics Education) and one of the new features we are adding is a podcast and webinar series based on selected presentations from our annual conference. We call the series OAME Talks and we hope it is popular. So we have just launched and our first episode is with Jon Orr and Kyle Pearce talking about their session called Making Math Moments Matter. For this episode we are only doing the podcast but not a live webinar. Instead we are just linking to a previous webinar that Jon and Kyle did. Next month we will be featuring Marian Small in both podcast and live webinar form.

Have you ever played the game SkyScraper. The premiss is simple you have an x by x (typically 4x4 or 5x5) and you need to place towers of varying height on each square. No row or column can have more than one tower of the same height. As hints, you are given which of the towers you can see when looking from the sides. In this post @markchubb3 has created some templates for doing these puzzles with relational rods as the towers. And don't forget to check out his templates for using snap cubes instead.

This new podcast is the work of @MathletePearce and @MrOrr_Geek where they take their three part framework and unpack it over several episodes. The focus here is one what makes good teaching and how do we do it in a way that ideas stick with kids. Lots of good ideas here and the promise of interviews with people in the math community to punctuate their ideas. Each episode has info and extra resources to extend your thinking on each topic.

A few new podcasts episodes added to the list. One from More or Less on the standardization of the Kg and one from @MrBartonMaths with a great interview with Hannah Fry. And a new podcast feed from @Numberphile. These long form interviews are great to show students (and teachers) behind the vale of those in the math community fighting the good fight. Brady really does a good job in talking to his guests. Check them all out at the podcast tab above

For fun, I took a Desmos sketch made by @MrCorleyMath and made it a bit more visual.

I love this blog post from @rougeux on how the poster on Byrne's Euclid: The first six books of the Elements of Euclid with Coloured diagrams and symbols. The blog post goes into meticulous detail on everything that went into the making and design of the poster.

I am not sure how I didn't know about this YouTube channel before but after listening to the first episode of the new Numberphile podcast, I was introduced to 3Blue1Brown. These are great visuals on all kinds of math topics. He tries to take complex ideas and break them down visually in a way that a high school math student might understand. A few you might like to start out are this one on why a sphere's surface area is 4Pir2, the essence of calculus or how Pi was almost 6.28...

I actually saw this a few months ago when @msbjacobs showed it at a meeting and I loved it. It's a short excerpt of a longer interview by Hannah Fry with Roger Penrose and he talks about how he was held back in school because he was a slow calculator.

I am a sucker for anything to do with randomness. In this case, it's how we really don't understand its nature. This is good for all grade levels but has some discussion of combinatorics also.

If you haven't experienced the moment when you pause a Desmos activity in your class, then you are missing a magical moment.

These are images in this Tweet but they both come from Desmos sketches. One using the geometry and the other using the regular calculator

A nice visualization from @MonaChalibi on the number of natural disasters over time. Note, she realized after that she spelled droughts wrong.
