MATH TOOLS NEWSLETTER - FEBRUARY 8, 2008 - No. 60 ***FREE ONLINE OPPORTUNITY FOR TEACHERS OF GRADES 5-9 Using Technology and Problem Solving to Build Algebraic Reasoning http://mathforum.org/nsdl_mathtech/online/ The Math Forum has been hosting a series of online workshops for teachers who work with students in 5th through 9th grade. Teachers are exploring how technology can help students build algebraic reasoning as they model and solve contextualized problems using a variety of representations, including graphs, tables, equations, and words. Each participant's $100 workshop fee is being covered by a National Science Foundation (NSF) grant, affording participants the convenience of anytime, anywhere online learning. The next workshop will be offered March 3 - April 12. Certificates of completion will be available for participants finishing the six weeks of interaction. For an overview with additional detalis, visit: http://mathforum.org/nsdl_mathtech/online/overview.html Deadline for applications is Monday, February 25, 2008. http://mathforum.org/nsdl_mathtech/online/apply.html \|/ ***FREE TPOW ACCESS FOR STUDENTS Technology Problems of the Week (tPoWs) http://mathforum.org/tpow/index.direct.html Students are invited to use the link "Submit your answer" to share their solutions, and then "self-mentor" using specially designed hints, checks, and suggestions for extensions. \|/ As you browse the catalog, please take a moment to rate a resource, comment on it, review it -- or start a new discussion! ***FEATURED TOOL Tool: The Futures Channel Jenna Bowles, Editor http://mathforum.org/mathtools/tool/36244/ The Futures Channel produces educational micro-documentary videos that show students how professionals are using math, science, technology and engineering in the real world. Teachers often describe the movies as an answer to that famous question, "Why do I need to learn this?" ***FEATURED TOOL Tool: LSRL, Residual Plots, Data Transformation in Sketchpad Nate Burchell http://mathforum.org/mathtools/tool/36550/ Drag seven independent points on a scatterplot, or send them to predetermined arrangements, to enhance understanding of correlation and the implication of changes. ***FEATURED TOOL Tool: Taylor and Maclaurin Polynomials on Sketchpad Nate Burchell http://mathforum.org/mathtools/tool/36557/ This Sketch allows the user to see the first ten Taylor (or Maclaurin) polynomials for a function. ***FEATURED DISCUSSION Physical models of surfaces http://mathforum.org/mathtools/discuss.html?&do=m&thread=g_____g-24 Peter Ash explains, "I would like to obtain an actual physical model of a surface exhibiting negative curvature." ***FEATURED DISCUSSION Use of Video http://mathforum.org/mathtools/discuss.html?&do=r&msg=36106 MrT68 writes, "Here is a website I created using some of mine. I have also loaded them at teachertube and put together a website for our school's benchmark exams." ***FEATURED DISCUSSION Curve of Best Fit for Car's Skidding Distance http://mathforum.org/mathtools/discuss.html?&do=m&thread=a2_____g-4 Jesdisciple asks, "Chapter 8 in the Texas Drivers Handbook lists the distance a car will skid after the breaks are applied as (MPH, feet). Does anyone have an idea how to solve this?"
