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

** what is pi?** Pi comes from
dividing the distance

** what is “Pi Day”?** We can write March 14
as 3-14, and 3.14 is the beginning of that special number

**my
favorite Pi Day SONGS: ***(one may be a winner in the National Museum of Mathematics’
contest in honor of 2015’s “Pi Day of the Century”!)*

• I wrote **“American Pi”
**(see http://educationforatoz.com/images/2015_Larry_Lesser.pdf for a lyric or click **HERE**
to hear a demo recording) 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 implicitly set 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). Varying versions
have appeared in several books and journals, such as the February 2006* MAA Horizons *and a rockin’
rendition by* *Calvin Coolidge (a band
of then-high schoolers in Cleveland) appears at* *http://www.youtube.com/watch?v=Ll_45NomcFk
or http://video.google.com/videoplay?docid=9202713347829076799&hl=en. *On 3/14/15, the National
Museum of Mathematics announced that my song won its “Pi Day of the Century”
song contest*** ,** and this yielded media coverage (see bottom of this
webpage) as well as an article in

• 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*. Click **HERE** to

Mathematics Education* (http://educationforatoz.com/images/2015_Larry_Lesser.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://museum2.utep.edu/archive/math/DDpiday.htm** **

**pi day
classroom COMICS activity I wrote: **“Cartoon Corner” on p. 383 & 387 of the
March 2007 (*12*(7)) *Mathematics Teaching in the Middle School*

**RESEARCH ARTICLE I co-wrote about family math nights which
featured pi activities:** “Parent Power
Nights: A Vehicle for Engaging Adults/Families in Learning Mathematics.”(Nov.
2008) *Adults Learning Mathematics

__my Pi Day Outreach__: Over the
years, I’ve helped produce pi day events for elementary students
(e.g., Canutillo ES; see, for example, the article starting on p. 36 of http://www.alm-online.net/images/ALM/journals/almij-volume3_2_b_nov2008.pdf), middle
school students (e.g., Henderson MS, as on p. 13 of http://mikestoneblog.com/_portfolio_page/multimedia/magazines-newspapers/magazine-props-for-kids-1.pdf; EPJA,
see http://www.math.utep.edu/Faculty/lesser/EPJA2008piday.gif
or https://thejewisheducator.files.wordpress.com/2013/03/lesser1.pdf), high
school students (e.g., Emery HS in Houston; see the article starting on p. 6
of http://tctmonline.org/TCTMdrupal/sites/default/files/docs/TMT_archive/TMT_2000s/TMT_2004_Fall.pdf), and
college students (e.g., with the UTEP Math Dept's
undergraduate math club, Club Zero: see, for example, the last page of http://www.math.utep.edu/dept/maxima/MaximaFall07.pdf). Finally,
I was announced by “Math Matters at Taylor and Francis” social media as
a winner of its 2015 Pi Day haiku (“pi-ku”?) contest
for this entry: In America, Pi Day of
the Century….was transcendental!

the 2012 movie Life of Pi is based
on a book about which mathematical questions are posed in “Slices of Pi:
Rounding Up Ideas for Celebrating Pi Day” in pages 6-11 of the fall 2004 *Texas Mathematics Teacher*, which you can
