But, when a student is given the chance to make their own graph and then answer questions, it gives them real ownership of their learning." ***FEATURED DISCUSSION Interactive whiteboard resources - elementary teachers http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_81683_g-1 Mathsframe.co.uk announces, "I am a primary school teacher from England. I have been making maths resources using Flash and have recently launched a website to share these resources with fellow teachers." ***FEATURED TOOL Tool: Mellow Yellow: Interpreting Graphs http://mathforum.org/mathtools/activity/82774/ Sketchpad Compare different representations of motion: a story, a position graph, and the motion itself. Create a graph that matches a story, or write a story to match a graph, and check either by watching Mellow Yellow move. ***FEATURED TOOL Tool: Rotation transformation - Math Open Reference http://mathforum.org/mathtools/tool/83049/ John Page A web page and interactive (Flash) applet demonstrating the rotation transformation. User can drag a polygon and cause it to rotate about a point. The point (center of rotation) can be also dragged and the rotation repeated about the new point. ***FEATURED TOOL Tool: Classification of Quadrilaterals http://mathforum.org/mathtools/tool/81672/ Alexander Bogomolny An interactive Java illustration that highlights specific properties of various quadrilaterals. Quadrilaterals may be convex, orthodiagonal, cyclic, inscriptible, having parallel or equal sides, equilateral, or equiangular. ***FEATURED TOOL Tool: Rock, Paper, Scissors http://mathforum.org/mathtools/tool/81578/ nrich.maths.org This is a simple online version of the game rock, paper, scissors. The webpage includes a background of the game, rules and an applet complete with images of hands showing rock (closed fist), paper (flat hand), scissors (two fingers). Ideas to extend the game are included. ***FEATURED TOOL Tool: Sequences and Series of Functions Grapher http://mathforum.org/mathtools/tool/81817/ Barbara Kaskosz The applet plots consecutive terms of a user-defined sequence or a series of functions. Those can be, in particlular, Taylor series and Fourier series. A piecewise defined limit function can also be entered and plotted. Many demo examples are provided. ***FEATURED TOOL Tool: Triangle Classification http://mathforum.org/mathtools/tool/81671/ Alexander Bogomolny An interactive Java Illustration for classification of triangles. The types displayed are scalene, acute, obtuse, right, isosceles, and equilateral.
