Math Links for Week Ending April 15th, 2016

Jo Boaler has a new paper touting the importance of visual representations in math class. And clarification that this is not just for those who struggle but all students benefit from seeing mathematics. The paper is available for the next couple of days via the link below. And also look at the other teacher and visual resources as well (later you will just need a free account on YouCubed to download them). The Internet was certainly a buzz with this announcement. And check out this visual summary made by @wheeler_laura

This is a pretty sweet (and nice and simple) Integer game from @mr_stadel. He got feedback and made some nice adjustments for the final version.

I found a new Twitter feed: @MathVineADay with some short (IE vine-like) videos of math related stuff.

Last week @MrSoClassroom blogged about using coding in math class and had some examples of doing so with order of operations. This week he tweeted out some more code for doing the same

Last week I was at the TVDSB STEAM conference and sat into a session on combining geometry and art via Mandalas by @MrsAdamsPJ &@TweetMrJamieson.. So I made this web sketch to show how that could be made dynamic. All their stuff can be found here.

After I posted that, @HarMath pointed out that it reminded him of Fraction Talks and so I made a Fraction Talks version.

And I saw a few samples of this property of area of a trapezoid (see the above) and had this kicking around. So I finished it and posted it too.

The Math Wars continue to rage.  And in light of the new "math focus" of the Ministry of Ed here in Ontario, here are @rachelinch & @alexoverwijk on the CBC talking about having a more problem solving approach to math is better than just drill and kill

I like using this trick when talking about calculating slope but I have not seen it done to this depth before.

I love the connection of the 3D fractals of the Menger Sponge to Pi in this @standupmaths video. Download the template yourself to make your own

I love this animation of how when you combine simple linear motions you can get more complex motions. Reminds me a bit of this GSP sketch I made where I talk about combining velocity vectors to create circular motion.

I really love visual proofs. Especially if they show something very clearly.
