Too bad I didn't catch this one for last weeks post but better late than never. This is a TED-ED talk about the mathematics of online dating. Specifically how the site OKCupid calculates its matching algorithm. Some really simple math but ingenious. Could easily be used to talk about statistics and the geometric mean or just the nature of what an algorithm is and why computers are so good at calculating them. http://www.youtube.com/watch?v=m9PiPlRuy6E

Here is a great data set about taxi cab fairs in Toronto. Totally linear data that could be adapted to any grade 9 or 10 applied or academic class.
Chris Hadfield talks about some applications of using math on the ISS. If you have seen any of Chris' videos you know that he has been a great ambassador for the space program (just check out is AMA - ask me anything - on Reddit). Anyway in this brief video he refers to Pythagorean theorem and trig
One of the latest from Numberphile is a great heads up for Pi day. This time about how precise do you need to know Pi to calculate the circumference of the universe. More specifically, how many decimals are needed for most practical applications.
Nice images of what 200 calories look like for different types of food. Its a different sort of visualization than a regular graph. Thanks to Mark Esping for this one.
On this day after Valentine's day, what better way to celebrate than calculating how likely it would be to find love (and life on other planets). Could be used for percents or probability

I think that applications like this "Robot" kit is a great way to apply ideas in math classrooms. However I disagree with one of the things the guy says in the video. That "kids these days don't want to learn abstract math". I don't think most kids ever want to learn abstract math. However it is important to try to learn abstract content. Not for the sake of the content but for the sake of the brain exercise needed to master that content. Regardless, this is pretty cool. http://mashable.com/2013/02/08/robots-drones-classroom/

One of the things you can do if you have a YouTube account (and if you have a Gmail account, by default, you have one), is to create playlists of videos. Here a teacher has created two play lists. One to fit in to the Advanced Functions course and one for the grade 11 University course. And what she has done is linked the videos to the textbooks she is using by labeling the videos by textbook section. So the Advanced functions is linked to the McGraw Hill Textbook and the Grade 11 U videos are linked to the Nelson book.

Although this teacher is talking about doing this for grade 8 curriculum, here in Ontario that fits the grade 10 academic curriculum. Teaching about perpendicular lines with geoboards but it could be done just as well with graph paper. http://untilnextstop.blogspot.ca/2013/01/perpendicular-slopes-and-geoboards.html

How do you show a graph when you are on the radio? You convert it to music and have an opera singer sing it of course. I have just been getting caught up on some of my older podcasts and heard this great piece by Planet Money. Rather than just describe the graph seen on the right, they converted it to music and had it sung. Perfect for showing that data can be represented in many ways. http://www.npr.org/blogs/money/2011/04/27/135737940/the-case-shiller-index-sung-as-opera

Is
the Body Mass Index (BMI) really that useful if it says people like
Brad Pitt are considered overweight? In fact, Dwayne "The Rock" Johnson
is actually obese according to the BMI. Here's another adjusted measure.
This could be used for teaching order of operations in Gr 7 or Gr8.
Just sayin http://www.bbc.co.uk/news/magazine-21229387

Numberphile just released a video post compiling the results from their quest to find YouTube's favourite number. Here is the blog post that gives the detailed results of the data as well as the summary video and original videos. Great for any Data Management class http://periodicvideos.blogspot.co.uk/2013/02/popular-numbers.html

In the Numberphile post below you may have noticed that there are some limit expressions. These were produced by an online LaTeX equation editor that lets you create equations and then paste HTML code into your web pages (or images into your documents). A useful thing if you have ever needed to put math in a webpage http://www.codecogs.com/latex/eqneditor.php
