MATH TOOLS NEWSLETTER - MARCH 5, 2005 - No. 24 We have added a new Technology problem (tPoW) to Math Tools. Feel free to have students submit their solutions to us following the "Submit your answer" link. ***FEATURED TPOW Technology PoW: Runners http://mathforum.org/mathtools/tpow/17540/ Tell how a runner's step size predicts the time it takes to run from the building to the tree. A link to a Java applet from NCTM's "Electronic Examples, Principles and Standards for School Mathematics" is provided to help students think about the problem. ***FEATURED DISCUSSION Tool Usage Sites http://mathforum.org/mathtools/discuss.html?&do=m&thread=m7___tool__g-1 Tackweed asks, "Would those of you who have current web pages where various math tools are used by classes/students please provide the url? I am looking for specific tool use in context as opposed to listings of tools." ***FEATURED DISCUSSION Formulas http://mathforum.org/mathtools/discuss.html?&do=m&thread=m6_____g-1 Mrs. J comments, "I have noticed over the last few years that students are having more difficulty with the concept of formulas. Am I alone or have others seen this problem?" ***FEATURED DISCUSSION The NEW Classroom http://mathforum.org/mathtools/discuss.html?&do=m&thread=_____g-55 Susan asks, "I have a friend who has the opportunity to give input on purchases for all the new mathematics classroom. What should she buy in the way of technology? Think ten years out because the funds may disappear!" ***FEATURED ACTIVITY Activity: A Lulu of a Function Craig Russell http://mathforum.org/mathtools/activity/17629/ This activity guides exploration of functional aspects of the Lulu microworld. Functions called for are not y = f(x) functions; domains/ranges are either directions or coordinates of points. ***FEATURED ACTIVITY Activity: Analysis of Bivariate Data Using Fathom Freudenthal Institute http://mathforum.org/mathtools/activity/17471/ The resource consists of a series of linked concept maps that lead students through steps of importing and analyzing two-variable data using Fathom. Students follow illustrated steps to import data from Internet sites, create graphs, calculate statistical measures, and create a report. A further data set is assigned for a project to be handed in using the same steps. Designed for Ontario Curriculum Grade 12 Data Management (MDM 4U0).
