MATH TOOLS NEWSLETTER - AUGUST 7, 2004 - No. 17 Twenty-one participants who traveled to Philadelphia and twenty-four online members of the Math Tools community spent last week getting familiar with the recently implemented features of the Math Tools site. They have collaborated to create classroom activities, software-related resources, and services for themselves and others. http://mathforum.org/workshops/toolfest04/ ***FEATURED DISCUSSION Teaching Mathematics as a Science http://mathforum.org/mathtools/discuss.html?do=m&thread=_____round-99 Bethany writes, "It seems that the pervading philosophy of teaching and learning mathematics is pushing us as educators [...] to make math more of a discovery process than just giving students the concepts and trying to process them.... What do you think? ***FEATURED DISCUSSION Your Favorite Tools http://mathforum.org/mathtools/discuss.html?do=m&thread=_____round-98 Don Link started this thread in the Roundtable Discussion and a few other people have chimed in so far. He writes, "I'm fairly new to the Math Tools community, and I thought it would be useful if some of you 'longer-timers' would share your N favorite tools cataloged on the site (I'm thinking like your top 10, but any value of N would be fine)." ***FEATURED DISCUSSION Traffic Jam Activity http://mathforum.org/mathtools/discuss.html?do=m&thread=_____round-95 The Traffic Jam Activity was our first Tool Fest activity. Read comments noted during our face-to-face discussion and also thoughts posted by the community as they tried the activity. ***FEATURED TOOL Tool: Parabola in Standard Form (Java Sketchpad version) Annie Fetter http://mathforum.org/mathtools/tool.html?id=12142 This applet, created with Java Sketchpad, allows the exploration of a parabola in standard form, where the coefficients a, b, and c are restricted to multiples of 1/2. A sister sketch allows unrestricted coefficients. ***FEATURED TOOL Tool: Parabola in Standard Form (Sketch) Annie Fetter http://mathforum.org/mathtools/tool.html?id=12146 This sketch allows the manipulation of a parabola in standard form. On the first page, the coefficients a, b, and c are restricted to multiples of 0.5. On the second page, they are unrestricted and can be set to exact numbers using the "fine controls." ***FEATURED TOOL Tool: Centers of Triangles Wing Kuen Cheng http://mathforum.org/mathtools/tool.html?id=12260 See the different centers of a triangle and how they relate to the medians, perpendicular bisectors, and altitudes of the triangle. Students can manipulate the triangle and try to answer the follow-up questions at the bottom.
