What makes us passionate about math education?
What IGNITES us?
Earlier this week, we began releasing daily a new five
minute-long clip of a different Math Forum staffer or
colleague, each speaking breathlessly about our passion for
math education while 20 PowerPoint slides advanced every 15
seconds — ready or not!
The fourth of these videos came out today, with more yet to
come down the pipeline (release date in parentheses):
Andrew Stadel: "Number Sense: I Don't Like This Game
Anymore" (Monday, 12 May)
Gail Burrill: "Why Statistics is Important in Education"
(Tuesday, 13 May)
Kyndall Brown: "Cooking with Data for Access and Equity"
(Wednesday, 14 May)
Peg Cagle: "Transformational Geometry" (Thursday, 15 May)
Dan Meyer: "Teaching the Boring Bits" (Friday, 16 May)
Annie Fetter: "Who Cares? (About What?)" (Monday, 19 May)
Check back daily for the next in this series of Ignite talks
from the 2013 conference of the California Mathematics
Council - Northern Section (CMC-North).
Don't want to wait? Click a talk's title to download its
corresponding PowerPoint slides — or tune in to the complete,
unedited video of the whole session, which features commentary
by Steve Rasmussen, minus the slides:
CMC-North gave the Forum the oppportunity to carry on the
Ignite tradition started by Key Curriculum Press. For more

PoW taking place: math problem-solving moment of the week
"We decided to put our reflection first because we each
learned something a little different from this problem, as our
explanations will show. (Kira writes) I'd like you to know that
I made A LOT of mistakes. I had the right idea — making a
chart — but my first mistake was that I did not start off with
the same number of small and large cups. Also, I didn't read
the question right...."

Math Girls Talk About...
This past Sunday, Bento Books published the first volume in a
new Math Girls spinoff series, Math Girls Talk About...
The story in Math Girls Talk About Equations & Graphs unfolds
as dialogue among four teenage characters. Subtitled
"Fundamental Skills for Advanced Mathematics," this latest
translation by Bento Books introduces equations and graphs to
middle- and high-school students who have learned basic algebra.
Freely download the front matter, first chapter, index, and
table of contents, which lists these chapters, each with
problems for the reader to solve:
Letters and Identities
The Appeal of Simultaneous Equations
Equations and Silhouettes
Proportions and Inverse Proportions
Intersections and Tangents
Bento Books first appeared in these pages two and half years
ago, when they translated and published the young adult novel
Mathematical Girls — also by author Hiroshi Yuki — the
Japanese language version of which has already gone through
some twenty printings.
Now taking place: math education conversation of the day
"You know what is crazy? My mentor and head of our math
department met with the writer of the Common Core State
Standards and had no intention of there being any simplifying
of radicals. It is unnecessary with the modern use of the
calculator. New York State decided to go against that and add
it back in."
- Vivian, posted to the secondary (grades 9-12) discussion
group of the Association of Math Teachers of New York State
Really Big Numbers
This coming Monday, 12 May, the first book written for kids
published by the American Mathematical Society (AMS) will hit
In Really Big Numbers, mathematician Richard Evan Schwartz
leads math lovers of all ages on an illustrated journey through
the infinite number system. The book begins with small, easily
observable numbers before building up to truly gigantic ones,
like a nonillion, a tredecillion, a googol — even ones "too
huge for names" — all presented in fresh and relatable ways.
Preview Really Big Numbers by downloading a colorful
seven-page PDF bursting with fun figure facts such as
a monkey has about 100,000 hairs on its head
if everyone joined together in a giant chain and lifted
off the earth, on the right day they would reach about a
quarter of the way to Mars
you could cram about 20 billion grains of very fine sand
into a basketball
a googol atoms would fill the observable universe about
100 quadrillion times over
Really Big Numbers may be a first for AMS, but it's the
second book for children by Schwartz, Chancellor's Professor of
Mathematics and Director of Undergraduate Studies at Brown
University. In 2010, A. K. Peters/CRC Press published his book
about prime numbers and factoring, entitled You Can Count
