Any time you can trick kids into doing math problems by hiding a "worksheet", I think it's a good thing. And if you have someone who builds an activity and shares it out, even better. Here @theShaunCarter has created a game to help students practice finding the zeros of quadratics. The downloads are there so you can create your own set of cards. Note that depending on what course you are taking, you might have to pitch some cards. I like the fact that the game encourages factoring by having the game be: giving an x value and students checking if their expression equals zero (so having a factored expression is most efficient). And as an added bonus, he generated this cool tool to generate the x value they have to use.

I like when you can take a statistical concept that often students only (usually) ever see as abstract and make it visual. Here @samjshah uses Geogebra to visualize the effects of changing data on the sum of the squares and the standard deviation of a small data set. Nicely done.

Here's a comparison of North American teaching styles versus Japanese styles. The premiss is that in Japan they have much better success by focussing on problem solving while we focus on just getting answers and memorizing algorithms. I tend to agree with this notion. I think it's a good read but it reminded me of this video from Phil Daro (which I know I have shared more than once here.

Phil Daro - Against "Answer-Getting" from SERP MEDIA on Vimeo.

This could be a totally fun thing to do with just about any group of kids (provided you have enough pencils.

I'm not sure how I missed this during the Olympics but I love this representation of every medal winner of the 100m in the modern olympics. Super for linear scatter plots. Check the site out for more cool visualizations of this data.

Here is a great way to incorporate poetry into your math class. How about a Fibonacci poem.
