Rubric: Implementing Standards for Mathematical Practice


Three teachers have developed a rubric that uses the eight Common Core State Standards (CCSS) for Mathematical Practice to evaluate classroom tasks and teacher actions.

A product of the Park City Mathematics Institute (PCMI) Secondary School Teachers Program (SSTP), freely available as a PDF or Microsoft Word document, join dozens of other PCMI resources for educators:


PoW taking place: math problem-solving moment of the week

"I know this because turning x + 1/x = 5 into a quadratic equation and breaking out the quadratic formula will just be too messy. Instead we find a pattern: (x + 1/x)² is x² + (2 * x * 1/x) + 1/x² = x² + 1/x² + 2! (where the explanation point is NOT factorial). But look here!...."

Win a TI-84 Plus C Silver Edition Calculator


Love your TI-83 or TI-84 graphing calculator? Tell Texas Instruments why for a chance to win their new TI-84 Plus C Silver Edition!

This new, rechargeable model features all the familiar functionality of TI-84 Plus Technology, now enhanced with full-color capabilities. The TI-84 Plus C Silver Edition even imports photos and overlays graphs for display on its back-lit, high-resolution screen:


Open to legal residents of the United States aged thirteen and older, this short essay contest opened Wednesday, and ends in less than a month. Get inspiration — and not a few laughs — by reviewing others' submissions, which so far include poetic pleas, eulogies to TI-83s and TI-84s now out of commission, tales of mathematical cunning and survival, programming pranks, and at least one account of a prom invitation projected via a TI calculator to a classroom TV:


Now taking place: math education conversation of the day

"This book is an experiment in a new way to put together an edited collection of writings. Potential authors are encouraged to contact David Moursund or Robert Sylwester about submitting a chapter based on Chapter 10 or other ideas of their own choice. The book will 'grow' as new chapters are integrated."

Math Awareness Month and Mathematics of Planet Earth 2013


This April, the theme of Mathematics Awareness Month (MAM) will be the Mathematics of Sustainability. To celebrate, the Joint Policy Board for Mathematics (JPBM) invites educators to participate in the Sustainability Counts! National Initiative. Use your own lessons on sustainability, implement the Energy Challenge, or teach one of MAM's model lessons:


The official announcement of MAM 2013 states, in part: "Humanity continually faces the challenge of how to balance human needs against the world's resources while operating within the constraints imposed by the laws of nature. Mathematics helps us better understand these complex issues and is used by mathematicians and practitioners in a wide range of fields to seek creative solutions for a sustainable way of life."

Mathematics Awareness Month is sponsored each year by JPBM, a collaborative effort of the American Mathematical Society (AMS), the American Statistical Association (ASA), the Mathematical Association of America (MAA), and the Society for Industrial and Applied Mathematics (SIAM). Visit mathaware.org for essays, linking icons, a sample press release template, and more.

This year, JPBM's member organizations also join over a hundred other scientific societies, universities, research institutes, and foundations from around the world in dedicating 2013 as a special year for the Mathematics of Planet Earth.
