Wir sing ein Volk. Berlin Wall Brandenburg Gate LEGO

Wir sind ein Volk (We are one people) - In 2015, a 2 Euro commemorative coin was released commemorating the 25th anniversary of the reunification of Germany. The Berlin Wall going up, and coming down, in my lifetime is a big deal. The coins show people celebrating in front of the Brandenburg Gate, in Berlin. Also on the coin: on the edge of the coin: EINIGKEIT UND RECHT UND FREIHEIT (Unity and Justice and Freedom), 25 Jahre Deutsche Einheit 2015 (25 years of German Unity25 years of German Unity). A number of years ago I made a PowerPoint on the Berlin Wall, chronicling the history of the Wall (my perspective). Berlin is one of my favorite cities. The Wall came down in 1989 and Germany was reunified in 1990. I have the 2 Euro coin and a LEGO model of the Brandenburg Gate in my office. Stop by and see it.

World Maths DayWorld Maths Day - Unfortunately this has past for 2009. I just now learned of this event - which is quite large and growing. It is the first Wednesday in March each year. The students play against each other in mental arithmetic games. Students are captivated by the fact that they are playing in real time. Each game lasts for 60 seconds, students can play as many games as they wish. BTW, "maths" is the short form of mathematics used in most of the english-speaking countries outside the US, where we use "math."

BuckyballThe graphic at the top is a "Buckyball" (after Buckminster Fuller) or fullerene. Buckminster Fuller invented the geodesic dome, which has a similar structure.
The Buckyball is a model of the C60 molocule, is made up of 60 carbon atoms. Mathematically, we call this shape the truncated icosahedron. It has 32 faces, of which 20 are regular hexagons and 12 are regular pentagons. See also and Buckminster Fuller Institute. He was even on a US stamp.

Two things noteworthy from the NCTM: (1) The Mathematics Teacher is an official journal of the National Council of Teachers of Mathematics (NCTM). It has been around for 100 years (it is actually older than the NCTM itself, because it started with the Association of Teachers of Mathematics). It is a wonderful resource for mathematics teachers. It's focus is secondary mathematics. The NCTM also has other quality journals. (2) The NCTM has recently released the Curriculum Focal Points which lists important mathematical topics which should represent major areas of content emphasis in K-12 classrooms. The document builds on the Principles and Standards for School Mathematics.

NUMB3RS is a drama about an FBI agent who recruits his mathematical-genius brother to help the Bureau solve a wide range of challenging crimes in Los Angeles (CBS - Friday nights at 10/9 Central - see about the show). NCTM and Texas Instruments have partnered with CBS to put together the We All Use Math Every Day Program, which provides math activities related to the math topics seen on the TV episodes of NUMB3RS. Check it out, I think you'll like NUMB3RS and We All Use Math Every Day.

Pi Day a Big Success

On April 24, 2003 Pi Day was held at Western Illinois University. Eighty-five fifth graders from Havana, Illinois came to campus for a day of fun math activities and pizza pie. There teacher wrote this response:

"All of the teachers, chaperones, and students had a great day at WIU from beginning to end. It was very well planned and coordinated. Lunch on a field trip is usually not peaceable, but having 2 groups at a time and puzzle activities was great. Every part of the day was well done. Please tell your students how much we appreciated their efforts as well as the WIU Math Dept.
Student response to the day, the food, and the campus were all positive. One student was heard to say while walking from the bus to the Union, "Wow, I didn't think I'd ever want to go to college, but I'm going to have to work hard so I can go." [emphasis added] Responses to activities were equally enthusiastic. There were several groups doing Mathemagic Sheets on the way home.
Thanks again from all of us. Karen Barrett, Havana Schools"
