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 under-served 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.uni-bayreuth.de/2957/
Spurred by the outcome of the first Trends in International
Mathematics and Science Study (TIMSS), Germany launched a
nation-wide "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
Inquiry-Based Way After All

- Teaching Mathematics: Opening up Individual Paths

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 British-born artist, whose work appeared in The New York
Times earlier this month, brings both curiosity and passion to
bear on his data-driven 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 on-field 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 tongue-in-cheek 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:
