The Geometer's Sketchpad Math Forum Classroom Resources

Interactive Geometry Classroom Materials || Main CIGS Page

Note: The Math Forum's CIGS pages are not maintained by Key Curriculum Press, the publishers of Sketchpad. Current and former employees of Key have contributed items, but the authors are not responsible for anything that does or does not work here. If you have items that you would like us to include in our archives, contact us to find out how to submit them. If there are sketches you'd like to see, please share your request on the discussion group geometry-software-dynamic. Sketchpad Resources at the Math Forum See also Sketchpad Resources on the Web Sketches, Activities, and Tours Geometer's Sketchpad Activity Center - Bill Finzer Activities include how to construct a fractal binary tree (recursion, fractals, scripting, and transformations (rotation and dilation); and exploring random walks (probability, iteration, and scripting). Sketchpad v.3 Gallery - Nick Jackiw and Bill Finzer A wide sampling of constructions, analyses, drawings, and design: Arcs and Architecture; Algebra and Beyond; Physics; Statistics; Curves; and Poincaré Disk The Ferris Wheel - Jim King Step-by-step instructions for constructing an animated Ferris Wheel using dynamic transformations and the Geometer's Sketchpad. Dirichlet Sketches - Jim King Dirichlet regions for three, four, and five points. GSP Intro Lab - Mike Riedy Setup; Toolbox; Useful Functions; Menus; and Graphing Spirograph Machine Lab (also called "Tea Cusps and Saucers") - Mike Riedy A lab that studies the effects (both mathematical and artistic) of circular motion as points rotate around circles. GSP Assessment Quiz - Mike Riedy Designed to be used in conjunction with Mike's Introductory Lab and Spirograph activities Three Small Explorations - Mike Riedy Rotation and translation, cycloid, and area of a parallelogram and rectangle. New! Finding Equations of Circles - Charlotte Kessler A handout to guide students through discovering the equation of a circle. Maximum Volume and Area - David Purdy Three explorations of optimization problems viewed dynamically. Early Sketches from Key Curriculum Press Chase Sketches / Clock Sketches / Derivative and Integral Sketches / E and M Sketches / Exponential Sketch / FPU Necessary Sketches / Miscellaneous Sketches / Polyhedra Sketches / Wittgenstein Thought Sketches - Bill Finzer, Rob Berkelman, Dan Bennett, & Nick Jackiw Mechanical Linkages - Ken Koedinger, Nick Jackiw (Elevator doors, Peaucellier's Linkage, Sewing Machine, Windshield Wipers) Statistical Applications - Bill Finzer A Template for Napoleon's Theorem Explorations - Steve Weimar The Goal Angle Problem - Ken Koedinger MAA Meetings, Groups, Publications Geometry Turned On: Dynamic Software in Learning, Teaching, and Research Edited by J. King and D. Schattschneider, this book contains twenty-six papers about aspects of dynamic software for geometry. The book itself does not contain software, but the Math Forum site includes downloadable files for many of the papers in the book. MAA Meetings '96 - Orlando, FL Sketches and scripts from elliptic geometry and Poincaré disk drawing tools (Findell, Alexander); finding the triangle of smallest perimeter inscribed in a given triangle (Parks); extended concurrencies of a triangle (Wilson). MAA User's Group, Cincinnati, January 1994 Sketchpad presentations: Andrews - Conics; King - Circles; Schattschneider - Problems; Shimamoto - Topics in Geometry; Thornton - Triangles. Demonstrations of users' ideas; student work. Sketchpad Web Units Algebra and Calculus via Sketchpad - Ruth Carver Exploring equations for lines, parabolas, and tangents using the Geometer's Sketchpad. Introduction to Vectors - Gene Klotz Supplementary material to help students with their first encounter with vectors, and an experiement in the pedagogical possibilities of the WWW which allows nonlinear use of documents of all types, and of the Geometer's Sketchpad, which has internal possiblities for unveiling, animating, and tabulating, in addition to its dynamic capabilities. How to Morph in Sketchpad - Annie Fetter Adapted from a talk by Nick Jackiw at the NCTM National Meeting in 1996, this activity shows you how to construct a sketch that will change a simple polygon into a circle. Sketchpad Tessellation Tutorial - Cathi Sanders Step-by-step instructions for tiling the plane using Sketchpad. Follow the link to student tessellations from Punahou School in Honolulu, HI. New! Sketchpad for Little Ones - Geri Anderson-Nielsen A description and outline of activities that are done at Georgetown Day School with students from grades 2 on up. JavaSketchpad JavaGSP! - Annie Fetter A short tutorial: everything you need to know to make your first JavaSketchpad page. A quick reference is followed by other features, details, and considerations: what you need, what you do, what works, and what doesn't. Examples include Drawing a Solid and Its Net; Investigating Parallelograms; and Identifying Polygons. Annie's Sketchpad Activities - Annie Fetter Handouts of activities that incorporate JavaSketchpad, including: making a presentation sketch; investigating the properties of quadrilaterals; the Euler segment; morphing a simple figure to a circle; Napoleon's theorem; drawing a box and its net; and three roads to a parabola.
