CIRCULAR IRRIGATION http://mathforum.org/pcmi/hstp/resources/irrigation/
This lesson study, a collaborative professional development process, yielded three increasingly richer versions of the same lesson, as well as a lesson "hook" and reflections from the teachers who planned and implemented the lesson together.
Circular irrigation is a farming technique for watering crops by rotating equipment around a pivot. All versions of the lesson share the common learning objective of students using the area of known shapes to find the area of unknown composite shapes. The third version of the lesson further challenges students to use prior knowledge to compare strategies and relationships among various solution methods presented by their peers to find efficient ways to solve the problem. The circular irrigation lesson study was developed as part of the Park City Mathematics Institute, the 2011 edition of which recently concluded:

Now taking place: math education conversation of the hour
"I got to hang out with a bunch of 6th and 7th graders in a relatively underserved neighborhood here in Philly the last few weekends. I blogged about them here.... I showed them a picture of a big mug and a little mug. Only the little mug had a price. They all wanted to know, 'how much does the big mug cost?' and I asked them what a fair way to set the price would be. They had a really wide range of ideas...."

TOWARDS NEW TEACHING IN MATHEMATICS
http://sinus.unibayreuth.de/2957/
Spurred by the outcome of the first Trends in International Mathematics and Science Study (TIMSS), Germany launched a nationwide "model programme for increasing efficiency in mathematics and science education." Between 1998 and 2007, more than 1,800 schools took part, making it the largest such development project that the republic has ever carried out.
Known by its abbreviation in German, the SINUS project this year began publishing translations of its lesson outlines, textbook samples, pedagogy, word problem prompts, GEONExT activities, and other middle and high school teaching materials. Freely download monthly issues of "Towards New Teaching in Mathematics," such as
 Dynamic Geometry with Polygon Pantographs  Round and Angular: A Theme with Variations  The Quadratic Equation: This is a Topic to Be Taught in an InquiryBased Way After All  Experiencing Mathematics  Teaching Mathematics: Opening up Individual Paths to Learning

FLIP FLOP FLY BALL INFOGRAPHICS
http://www.flipflopflyin.com/flipflopflyball/infographics.html
Craig Robinson explains his illustrated statistical musings as the sum of a "love of baseball plus a love of visual representations.... what I'd have been doing when I was 12 years old had the Internet and Photoshop been available to me in the 1980s. And had I grown up in the States."
The Britishborn artist, whose work appeared in The New York Times earlier this month, brings both curiosity and passion to bear on his datadriven depictions of America's pastime. Often irreverent, sometimes whimsical  and occasionally ribald  Robinson's colorful diagrams and other statistical graphics have included
 716,083 pitches, which shows, as one continuous line, the distance covered by an entire season's worth of pitches  Team Names, an etymological Venn diagram  Biggest Payroll, which correlates onfield success and team salary totals  Celebrating at Home, an infographic that counts how often teams have clinched the World Series in front of their own fans  Born in the U.S.A., which charts the birthplace of every major leaguer from 1871 to 2009  Retired Numbers, a histogram of every jersey number retired in Major League Baseball (MLB)  Stolen Bases, which answers the tongueincheek question, "If bases were really stolen, how much money would MLB teams be losing?"
Robinson's book, subtitled "An Infographic Baseball Adventure," recently hit bookstores:
