Math Links for Week Ending April 18th, 2014

By now if you aren't following Dan Meyer then I don't know what you are waiting for. Dan was the keynote speaker at CUE this year and his talk was about using tech to fuel his perplexity. It's a great video and has tonne of great ideas. The tools he talks about are things like using an RSS reader (he and I both use Feedly), social book marking (he and I both use Delicious) and all kinds of other tools (Kyle at Tap into Teen Minds has also posts about using some of those tools and more here). You can see his website that created with resources on his talk here And although this is not necessarily related to using tech, here's a quote that I think says a lot about math teachers in general and why we may have a hard time connecting to students:
"I got into math teaching because I loved math. I needed no incentive to love math. Line up a whole bunch of problems, I'll do em. Attach your approval as my teacher and I'll do even more. But then they gave me students who, low and behold, don't love math like I do."
And to finish, in the end, he reveals the best tool that he has and that is math. Math is used to both create perplexity and to attack it. Nicely done.

Having just read Nate Silver's "The Signal and the Noise" reminds me how important the idea of confidence interval is. Here is a nice resource on things that are important when calculating confidence intervals.

Hey, I really like this Speed Match game for low level vocabulary practice. I think kids would play it and learn a bit of vocabulary to boot. I say it's low level because, in general, memorizing formulas or definitions is just that, low on the cognitive scale. But having kids memorize facts is not necessarily a bad thing. You just can't make it the prime focus of your teaching curriculum. So this game is a great way that you can get that stuff done for kids. And it works on the iPad. You can create your own game and do so without creating an account too. And another one from Mathy Cathy is Kahoot which is an online MC game where speed is of the essence.

Here's a really neat little applet made with Geometer's Sketchpad and put online. Perfect for introducing periodic functions. And it works on the iPad as well

Kyle at the Tap Into Teen Minds blog continues to catalogue all those 3 Act Math tasks being created around the web. He matches them up to curriculum (both common core and Ontario math) and usually adds his own worksheets and extras. This one is referencing one of Dan Meyer's from a couple of years ago and does a good job of dealing with rates of change. Click on the Access Math Task button to get Dan's original 3 Act task download and click on the Access Handouts button to get Kyle's handouts.

Do you want to give your kids a good straightforward traditional math review of Calculus. Then look no further than this online primer course given by MIT professor Gilbert Strang. It is intended for high school students so feel free to share.

Here's a really nice little intro to the idea of the Normal Curve. Thanks to Jordynne Lowe for this one.

Ok so this is mainly aimed at university Calculus students but it's still funny.

I love this image of an hour glass that demonstrates Archimedes proof that the volume of a cylinder is the same as the volume of a sphere plus the volume of a cone (with height equal to the diameter of the sphere for both the cone and the cylinder)

What is a little math if you can't include a little literacy. Yay for cross curricular images.
