Math Links for Week Ending June 9th, 2017

If you haven't seen @MrOrr_Geek's Math Before Bed then shame on you. The good news is that you're in luck. He just launched the companion site https://mathbeforebed.com/ . One of my favourite things about Math Before Bed is that you might get the impression that it's a book just for younger kids and that is probably who it's aimed for. But there are great questions that are framed in a way that a younger kid could do but touch on much bigger topics. And just about any of these could be used as a math starter or discussion piece in just about any class. And if you like this then you might want to get your own copy for your kids.

I have been neglecting my Found Data site for months now. I have many unfinished posts so I thought I would start to clean that up. One of first ones I had to get out was this Github site from Five Thirty Eight. Of course Five Thirty Eight are all about data and, as it turns out, there are a bunch of their stories that they have made the data sets available. And some of these sets are huge. Like this one about Classic Rock that has over 37000 pieces of data. So if you are looking for some interesting sets of data (especially categorical data) then check this out.

The other thing I did this week was start to generate some dynamic 3D sketches for the vector unit of MCV4U using Geogebra. These will probably only be useful to you if you are using the McGraw Hill Calculus and Vectors textbook as they are just dynamic versions of the chapter 7 examples (chapter 8 is to come).

In May our school board celebrated Canada 150 by asking students to come up with math questions that were about Canada that had an answer of 150. You can see some of the results here on Twitter. @Mathletepearce is also getting into the Canada 150 spirit by having students at his board complete some Canada 150 challenges. Here's a great proportional reasoning 3Act task dealing with a large rubber duck and the CN Tower.

I have seen this dynamic sketch for Geometer's Sketchpad but someone has done the math and created it for Desmos. Approximating Pi by the Method of Exhaustion is super cool and interesting that it has been done for centuries with little technology. Thanks to @Esping_Math for pointing out this one.

Tired of hearing about fidget spinners? Turn it into a math problem about how fast the spinner is going.

This is a neat site that is set up for people when they are out of school to brush up on their math skills. But there is a lot of stuff you could use in classes too.

Well said. Thanks to @kmarkpet for this one:

So simple but it could yield so much discussion. And check out @mathforlove's comment with a slight tweak.
