 Ignite Talks 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). For more fast, fired-up fun, watch our other Ignite talks from earlier conferences: http://mathforum.org/math_talk_landing_ignite.html 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. Math) helps us come up with a mathematically justified formula...." - Max, commenting on the Trig/Calc PoW's Latest Solution http://mathforum.org/pows/solution.htm?publication=4554 HPM-Americas Meeting The Americas Section of History and Pedagogy of Mathematics (HPM) will hold its annual meeting in Washington, DC, March 13-15, 2015. 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 Saturday, February 21: Host institution American University houses hundreds of old and rare mathematics texts — notably, Artemas Martin Collection     http://www.american.edu/library/archives/martin.cfm Karen Dee Michalowicz Collection     http://www.american.edu/library/archives/michalowicz.cfm Meeting organizers hope to visit these mathematical treasures, and further take in the Phillips Collection's special exhibit, "Man Ray - Human Equations: A Journey from Mathematics to Shakespeare": Now taking place: math education conversation of the day "Otherwise known as 'Things retired executive directors of @NCTM do in their spare time'!" - Annie, tweeted to @themathforum https://twitter.com/MFAnnie/status/560863713390264320 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.
