Math Links for Week Ending Sept. 8th, 2017

When I was at Twitter Math Camp this summer one of the "My Favourites" was from @SweenWSweens. He talked about using @Desmos Marbleslides challenges all the time in his class. Well he has put all of them in one Desmos Activity. Check it out at the link below

I think that the more real examples of how probability works we can show students the better. In this case the idea discussed is the "hundred year flood". More specifically the idea that what it means is not that once in every 100 years there will be a bad flood but instead there is a 1% chance every year that there will be a bad flood. These are two different things and they go through some of the math.

"John Urschel of the Baltimore Ravens was the only player in the N.F.L. simultaneously getting a Ph.D. in math at M.I.T. But after a new study came out linking football to brain damage, he abruptly retired" - this story is probably a nice general interest topic spanning sports to math. Listen below.

Sometimes I think that when it comes to transformations, dilatations are sometimes the hardest to describe. In this series of videos Dane Ehlart has a series of videos that shows them visually. Check them out below

And as an extra challenge Dane has some images where he asks to describe the dilatations then gives video solutions (see links below for solutions).
