Math Links for Week Ending Aug 5th, 2016

More Desmos cardsorts are coming. This one from @mjfenton is a nice short one that deals with the conceptual idea of what a solution of a system of linear equations is. This shouldn't take students too long but will give you a good idea if anyone doesn't "have it" at the most basic level. I also like the fact that it includes more than just the cardsort.

A few months ago I featured this report by about Sumo wrestling that was pretty rich with data (and kind of interesting). Now @joelbezaire has turned it into a nice little Desmos activity. Perfect for inferencing.

I love dealing with big numbers. And a billion of anything is one of them. And in this case the billion in question is one billion iPhones. On the @stupidcalc blog they go through the calculations showing that those iPhones could pave a road that was over 1400 miles long. Have your kids try the calculation themselves but take a look at the post for the details.

I like these Open Middle type questions. Here are some dealing from @MrJohnRowe with logarithms. Thanks to @jreulbach for pointing this one out.
