Math Links for Week Ending Feb 16th, 2018

I actually first created this post last year but updated it this week. If you are looking for some interesting data sets to analyze with your classes, look no further than Five Thirty Eights set of data sets used for their articles. The data sets were around before but recently then just made it even easier to get the raw data with their new site Check out my original (updated) post on how to use the data in your data classes

I updated a couple of GSP sketches to WebSketches this week on sine and cosine law. In both cases you start with a sketch to have students verify that each law works (with random triangles) then each has two pages of randomly generated triangles. One page where you solve for a side length and the other where you solve for an angle.

I sometimes don't think we give probability the treatment that it deserves. However, it is probably one of the few math skills that students need to be masterful with in order to navigate the world in a safe way. So with that I like this lesson that @MarkChubb3 lays out using this 3 player probability using dice rolling. Simple but it connects experimental and theoretical probability nicely.

I contend that when you are learning the multiplication tables, 7x8 is one of the hardest ones to learn. @JamesTanton uses that example to talk about understanding vs rote mathematics.

Some more work from @mathletepearce on his @mathisvisual site on integer multiplication. I made a few suggestions and he expanded on them to make this video and the accompanying images. Check out the site.

I was at the @OMCAMath Retreat and the speaker was @pgliljedahl. He started with this neat problem.
