Curious about who might be joining the math teacher ranks next? The Association of Mathematics Teacher Educators (AMTE) recently finished a national guide for the preparation of teachers of mathematics. Featured here in draft form for feedback five months ago, the completed "Standards for Preparing Teachers of Mathematics" addresses issues and challenges facing teacher preparation. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- PoW taking place: Math problem-solving moment of the week "Extra: To create a function, we can use the same strategy as in question 2.... To avoid negative values, it's better to use absolute value. This will result in two equations...." - Paige and Janelle, highlighted in the Algebra PoW's latest solution http://mathforum.org/pows/solution.htm?publication=4859 -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THE ORIGAMI REVOLUTION http://www.pbs.org/wgbh/nova/physics/origami-revolution.html After NOVA debuted its origami documentary on public television last week, it posted the whole program online for viewing -- also at no cost. Discussing topics ranging from immunology to dark matter and from homeland security to botany, "The Origami Revolution" takes viewers inside the labs and factories that are on the cutting edge of the science and engineering inspired by the art of folding paper. The film opens with Erik Demaine, a professor in the MIT Computer Science and Artificial Intelligence Laboratory. He is collaborating on a proof of a universal theorem that posits that any shape is foldable from a sheet of paper. Robert J. Lang, featured in these pages a decade ago, appears in "The Origami Revolution" as well -- now benefiting from the latest tools of the trade: a laser cutter and 3D origami design software called Origamizer, available for noncommercial use, with attribution to Tomohiro Tachi, who appears on screen after Lang. http://www.tsg.ne.jp/TT/software/#origamizer To start folding the fun into your primary class, check out "Puzzling with Paper," a collection of eight tasks by the University of Cambridge's NRICH Project: http://nrich.maths.org/12235 Middle school math teacher Fawn Nguyen has blogged about her students folding hamburger patty paper to investigate area, concluding "The smiles returned to their faces. I love teaching": http://fawnnguyen.com/investigating-area-paper-folding/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- Now taking place: Math education conversation of the day "Isn't the Measure Up curriculum (Hawaii) based on the work of Davidov? Has anyone heard if there has been success with their program? I have tried without success to obtain a copy of the textbooks. I've been looking for an elementary math curriculum that is more effective than the current (are we not 38th in international math [PISA score]?). Any recommendations?" - Paula, posted to the math-teach discussion http://mathforum.org/kb/message.jspa?messageID=10092482 -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THE MATH NINJA CHALLENGE http://competition.mangahigh.com/usmathninja Calling all North American math ninjas! A web-based math program is challenging students from across the continent to show their skills in a free math competition open to all schools and grade levels. At their own pace, in class or at home, students can work through standards-aligned games and question sets. The online environment of sponsor Mangahigh, first featured in these pages seven years ago, continuously adapts the Math Ninja Challenge to students' current level of demonstrated mastery. The prizes include gold medals for students and Amazon gift certificates for schools. Register for one of Mangahigh's training webinars, starting the first week of March -- also at no cost. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum at NCTM http://mathforum.org/ Online PD http://mathforum.org/pd/ Online Workshops http://mathforum.org/workshops/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pows/ Powerful Problem Solving http://mathforum.org/pps/ Mathematics Library http://mathforum.org/library/ Math Tools http://mathforum.org/mathtools/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/kb/ Join the Math Forum http://mathforum.org/join.forum.html Ask Dr. Math Books http://mathforum.org/pubs/dr.mathbooks.html Facebook https://www.facebook.com/themathforumatnctm/ Blogs http://mathforum.org/blogs/pows/ Twitter Feed http://mathforum.org/pd/twitter.html SEND COMMENTS TO: http://mathforum.org/electronic.newsletter/mfin.faq.html#feedback _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ An archive of all the Math Forum newsletters and directions for subscribing can be found at http://mathforum.org/electronic.newsletter/ ```
