 Camp Logic A new book of mathematical games and activities is coming out that introduces students to the nature and structure of mathematics. Informally and playfully, the authors of Camp Logic focus not on arithmetic, but rather on reasoning — in particular, the idea of implication: that new information can be derived from old through a chain of reasoning. This book includes material that Mark Saul, a Presidential Awardee for Mathematics and Science Teaching, and Sian Zelbo have developed together through their work with the Center for Mathematical Talent, an outreach program that operates through the Courant Institute of Mathematical Sciences of New York University (NYU), with funding by the Alfred P. Sloan Foundation. The activities of Camp Logic have been field tested in classrooms and math circles with students ages 8 and up from diverse backgrounds. Because its activities are modular, it can be used as the curriculum for a course or as enrichment. Subtitled "A week of logic games and activities for young people," Camp Logic includes five days' worth of games and activities such as The Game of Giotto A Says B Lies Jittery Soldiers Ginger's Pigeons Two-Row Nim and One-Piece Chess Magic Squares and 15 Game Preview and discuss the first chapter of the book by visiting A crowdfunding campaign to publish Camp Logic has already met and surpassed two milestones. Pledge your support before the Wednesday, 4 June deadline for acknowledgments, digital or paper formats, a live online book discussion with Dr. Saul and Ms. Zelbo, a signed original illustration of a cryptarithm puzzle, and more. PoW taking place: math problem-solving moment of the week "The other unique method I spotted came from Kanchan R. at John Gomes Elementary School. She used proportions to solve this problem. It makes sense because prices are all about rates — how many of this per that. Slick!" - Max, commenting on the Pre-Algebra PoW's Latest Solution http://mathforum.org/pows/solution.htm?publication=4392 Center for Mathematical Talent From their own website, the Center for Mathematical Talent mentioned above offers resources organized into three categories: Activities for Math Circles (all ages) Activities for Elementary and Middle School Activities for High School Freely download PDFs such as The Game of 24 Gumdrop Polyhedra Arm Folding, Knot Theory and Topology Topology Trail through the American Museum of Natural History Paper Folding Estimating Ratios The ABC Conjecture Problems from the 2012 Pan-African Mathematical Olympiad Now taking place: math education conversation of the day "I am of the 'old school,' so I will need some training regarding the new definition of trapezoid. I assume that all the states under PARCC are now using this definition. Is this correct? Can someone tell me if these statements would be correct under the new definition?" - Grace, posted to the secondary (grades 9-12) discussion group of the Association of Math Teachers of New York State http://mathforum.org/kb/message.jspa?messageID=9469557 Elaborations of the Practice Standards A lead writer of the Common Core State Standards (CCSS) for Math recently posted elaborations and examples of the Standards for Mathematical Practice, annotated for the 6-8 classroom. The PDF "Standards for Mathematical Practice: Commentary and Elaborations for 6-8" marks the original language of the standards with solid red circles that lead to examples of how they apply in the middle grades. A second section elaborates on the standards using narrative descriptions that integrate those earlier annotations and provide a coherent description of how the practice standards play out in grades 6-8 classrooms. commoncoretools.me, first featured in these pages shortly after it launched three years ago, has since featured posts such as Virtual Lecture Series! Lesson Plans to Accompany Published Tasks, a guest post by Morgan Saxby, a fifth grade teacher in Chesterfield County, Virginia Units, a Unifying Idea in Measurement, Fractions, and Base Ten Attend to the verbs in the Mathematical Practices, a guest post by Dev Sinha, a mathematician from the University of Oregon To B or not to B K-5 Progression on Geometric Measurement
