Math Links for Week Ending Aug. 8th, 2014

Something light because it's the summer. George Hart from a couple of years ago. Have fun linking your bagels. If you really want to link it to curriculum you could probably connect it to grade 8 or grade 9 with area of circles and then do some sort of investigation on how to measure the area after the cut.

I know this is US data but it is always good to have a data source to do some math with. This one is about the use of transit systems. Good for single variable analysis.

This new video from Numberphile is about primes. That is not a new topic for them. The thing I like about this one is that it shows a neat algorithm that only works for primes. It requires the use of factorials which, technically, is not part of the elementary curriculum but it would be easy enough to introduce and would be a nice little exercise in computation.

And here's the extra proof at the end of the above video

And finally another video from Numberphile. This one is from a couple of months ago and I somehow missed it. It's on the fun topic of the Monty Hall Problem. As far as I am concerned, you can't have too many reminders of this one. It's a really fun problem to do in your classes when talking about probability and especially tree diagrams (and in MDM4U conditional probability).

And there is more on the Monty Hall problem from Numberphile here with this playlist
