What makes us passionate about math education?
What IGNITES us?
Earlier this week, we began posting 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 third of these videos hit YouTube minutes ago, with more
yet to come down the pipeline:
Neil Cooperman: How Big Is Big?
Norma Boakes: Channeling Your Inner Mathematical Superhero
Bob Lochel: Language Matters in Math Class!
Melissa Jackson: Students with Disabilities in Gloucester
County Middle Schools by District Factor Group %
Proficient in Math
Phil Daro: Preview of the New Test for Teachers
Max Ray: Concept, Method, Procedure (The secret formula
for math success)
Check back daily for the next in this series of Ignite talks
from the annual conference of the Association of Mathematics
Teachers of New Jersey (AMTNJ).

PoW taking place: math problem-solving moment of the week
"Jo Boaler spoke at the California Math Council - North annual
meeting in 2014, and shared a lesson in which students not
familiar with integration or solids of revolution were tasked
with using only a knife and a ruler to find the volume of a
lemon. The students thought of many different ways of slicing
the lemon, calculating the volume of slices, and summing them
to find the total volume. A similar approach to 'Time to Make
the Doughnuts' would help students notice the ways in which it
does and does not make sense to treat a torus as a 'bent
cylinder.' On the one hand, a torus can be considered
equivalent to a cylinder whose height is the average of the
inner and outer circumferences of the torus. On the other
hand, simply thinking of 'unbending' a torus is problematic,
as Lee's solution above shows. Integral calculus (and
relatedly, Pappus' centroid theorem, explained here by Dr.
helps us come up with a mathematically justified formula...."

The Americas Section of History and Pedagogy of Mathematics
(HPM) will hold its annual meeting in Washington, DC, March
HPM seeks a variety of talks on the relation between the history
and pedagogy of mathematics. Talks directly relevant to the use
of the history of mathematics in mathematics classrooms are
especially welcome, as are reports of studies relating history
and pedagogy. Submit an abstract of a talk proposal by

Pi Day Contest
Calling pi enthusiasts everywhere: the National Museum of
Mathematics invites you to celebrate March 14 with original
pi-themed lyrics, limericks, and haiku!
Share your pi tunes, "pi-mericks," and "pi-ku" by Saturday,
February 21. The museum's judges will choose winning entries on
creativity and originality.
Enhancing public understanding and perception of mathematics,
the National Museum of Mathematics first appeared in these
pages over four years ago, during its Founding Capital Campaign
and construction near New York City's Madison Square Park.
