Math Links for Week Ending May 24th, 2019

Featured Links

One of the sessions that I did at OAME 2019 last week was on using Twitter (and other social media) as a PLN. After I got home I came up with this (longish) summary image to increase your presence on Twitter beyond just lurking and how to boost the visibility of your posts. I think the most important one is that one of the best things you can do is Retweet someone else's Tweet so that more people can see it (that's way better than liking it). If you have another tip, put it in the comments of the Tweet.

If you don't already follow @CShearer41 you should. Her simple little low tech geometry problems are fun. Here's one dealing with area where all you need to know is the area of a triangle and the area of a rectangle.

The triangle and rectangle have the same area. What fraction of the total is shaded? pic.twitter.com/JXCDnLI06c

Here is a cool simulation revolving around how many years you have left to live. Great for when you are talking about the reality of probability and how it relates to us. Thanks to @KMarkPet for this one

A month ago we had Collections added to the features of Desmos bookmarks. Now, if you have a collection, you can share it directly with teachers. Just copy the share link and distribute, then those teachers can add the entire collection to their own

A new book is out and it features the voices of some Ontario Educators (among others) like @AmyLin1962 @Marian_Small @Pi_Lab and @ggininewman. It's called My Best Idea from @rubiconpubs and is basically a summary of every one of the author's best ideas in education.

Two years ago I posted a video of a bunch of bricks that show the double domino effect. That 20s video went viral and has over 11million views right now. Here's a Desmos version of the same effect. Thanks to @JoceDage for pointing this out to me.

#MTBoS: Not intended to replace an active, hands-on, investigation (where Ss are measuring distances around and across cylinders). Rather, it can serve as a quick conceptual reminder for those that may need it later. 🙂 https://t.co/4Rdbxuy8T8 @geogebra #ITeachMath #LetSsTellYou pic.twitter.com/pknthE27RS

I saw this Tweet from @MFAnnie a few weeks back and I had not seen this video of her talking about her mother and how much math she did (unbeknownst to her mom) as she was making her quilts.

I liked this episode from @PlanetMoney on applied probability, that is, how James Holzhauer is using math to blow everyone away at Jeopardy.

TV ≠ real life Sources: A meticulous dataset created by @headlongpodcast (as heard on this week’s @thisamerlife). They watched 846 episodes across 30 seasons of the TV show COPS as well as ACS PUMS 1-year Estimate, from the Census Bureau 2016, Bureau of Justice Statistics, 2017 and FBI Uniform Crime Reports, 2017.
