Math Links for Week Ending Feb. 17th, 2017

I reposted this activity after some minor tweaks and I wasn't gonna mention it but a lot of people seemed to like it so I thought I would highlight it here. It's an activity that focusses on the geometric model of the Pythagorean theorem. There is a version that uses physical squares and also a version that uses Explain Everything as a virtual manipulative. There is also a Smart Notebook file and a dynamic sketch to use as an extension.

Someone pointed out this site to me from @jaccalder this week. There are tech things but more specific to Ontario, many resources for Grade 9 Applied math. This includes many tech tools including some Nearpod files and coding references to MFM1P.

I like marbleslides from Desmos and also like when teachers share their own versions. In this post @SweenWSweens shares his set of weekly marbleslide challenges Some of them are pretty hard and you would need many types of functions to solve them. The cool thing is some of his student solutions. So amazing. Thanks to @MaryBourassa for pointing this one out.

As many of you know, I love it when teachers share their work. And that goes for when they take a standard problem (you have goats and chickens and there are this many legs....". Here @Wheeler_Laura includes a PearDeck version of these activities where the teacher can see the student work as soon as possible (as it happens)

This TEDx talk from @MathforLove came out about a year ago but I only saw it for the first time this week. It is awesome. I love all the ideas about how to maximize your student's learning in your math classes. I also like the way he has the audience go through a cool factoring activity.

My youngest kid is 15 now so it's been a while since I've seen an Arthur episode but it seems that that show is still going and the subject of this episode is whether there is such thing as a math person. Go Arthur. Thanks to @duncantenacity for pointing this one out.

His visualizations on socially relevant data about countries were awesome and his interactive GapMinder tool was the way you could create your own but now @HansRosling has passed away. He once said "CNN got it wrong; Graphics are not about "How to make data look sexy", but to reveal that data is sexy!" He will be missed.

I love this data set that is represented 25 different ways. Which one would you pick as correct?
