be well-rounded….CELEBRATE   PI  DAY !!!!

user-friendly background:

Pi Day:  We can write March 14 as 3-14, and 3.14 is the beginning of the special number called pi.  Each March 14, more and more math classes, math clubs, and museums from coast to coast observe the day as PI DAY, a chance to celebrate the too-often-unsung beauty and connections of math in our world, including the number pi. (Here’s media coverage of a recent local Pi Day event:  http://www.math.utep.edu/Faculty/lesser/EPJA2008piday.gif)

Pi:  Arguably the most famous number not an integer, pi comes from dividing the distance around a circle by the greatest distance across the circle:  circumference divided by diameter.  This quotient or ratio equals the number pi no matter how big the circle is.  Even though this relationship has been known for thousands of years, it was only 300 years ago that the Greek letter pi (the first letter of the Greek word for “surrounding perimeter”) was introduced.  This number has a decimal representation which never stops or repeats, although modern computers have now computed pi to over a trillion decimal places!

 

 

resource ARTICLE I wrote for secondary and postsecondary teachers: “Slices of Pi: Rounding Up Ideas for Celebrating Pi Day” (fall 2004) Texas Mathematics Teacher, 51(2), 6-11. The issue is at www.tenet.edu/tctm/downloads/TMT_Fall_04.pdf.   The article was cited in the March 2005 issues of Mathematics Teacher and MAA Focus.

pi-themed COMICS classroom activity I wrote: “Cartoon Corner” on p. 383 & 387 of the March 2007 issue (Vol. 12, No. 7) of Mathematics Teaching in the Middle School

pi day RADIO SCRIPT I wrote:  At 8:58am every March 14, listeners of NPR-station KTEP (88.5 FM) hear a special “Pi Day” edition of the “Desert Diaries” show, which is archived on the Centennial Museum’s website:  http://museum.utep.edu/archive/math/DDpiday.htm

 

pi day SONGS I wrote:  

“Circle Song” (http://www.math.utep.edu/Faculty/lesser/circlesong.html) helps secondary school students recall –and distinguish-- the two most common formulas associated with circles.  Appears in Fall 2004 Texas Mathematics Teacher.

“American Pi”(http://www.math.utep.edu/Faculty/lesser/americanpi.html) -- presents historical highlights (and a mnemonic for the first 6 significant figures) of the number pi, ranging from an implied value in the Bible to the Indiana legislature’s 1897 consideration of a bill that declared pi equal to 4 [see Arthur Hallerberg's article "Indiana's Squared Circle" in the May 1977 Mathematics Magazine], and may be sung to the tune of Don McLean’s #1 hit “American Pie” (that was returned to the charts by Madonna in 2000). The Math Forum lists it (click here or here) as a great song for "PI DAY" (3/14), as does the March 2005 issue of MAA Focus!   Varying versions have appeared in May 2000 Mathematics Teacher, March 2003 Pi in the Sky, the 2004 Prometheus book by Posamentier and Lehmann Pi: A Biography of the World’s Most Mysterious Number, Sept. 2005 Journal of Irreproducible Results, and in February 2006 MAA Horizons.  Check out this rockin’ rendition by Calvin Coolidge (a band of then-high schoolers in Cleveland):  http://www.youtube.com/watch?v=Ll_45NomcFk or http://video.google.com/videoplay?docid=9202713347829076799&hl=en.
