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!

wrote for classroom teachers: “Slices of Pi: Rounding Up Ideas
for Celebrating Pi Day” (fall 2004) Texas

6-11. The article was cited in the March
2005 issues of Mathematics Teacher
and MAA Focus.
research ARTICLE I co-wrote about family math nights
in which pi activities played a big role: “Parent Power Nights: A Vehicle for Engaging Adults/Families in
Learning Mathematics.”(Nov. 2008) Adults Learning Mathematics International Journal, 3(2b), 36-52. http://www.alm-online.net/images/ALM/journals/almij-volume3_2_b_nov2008.pdf

pi day RADIO
SCRIPT I wrote: listeners of NPR-station KTEP (88.5 FM) have heard
several mid-March airings of 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
my favorite Pi Day SONGS:
• I wrote “Circle Song”
(http://www.math.utep.edu/Faculty/lesser/circlesong.html)
to help secondary school students recall –and distinguish-- the
two most common formulas associated with circles. Appears on p.6 of Fall
2004 Texas Mathematics Teacher.
• I wrote “American Pi”(http://www.math.utep.edu/Faculty/lesser/americanpi.html)
to present 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’
