  1. The Geometer's Sketchpad: Classroom Resources - The Math Forum
    Sketchpad and JavaSketchpad dynamic interactive geometry resources on the Math Forum Site: sketches, activities, and tours; MAA meetings and groups with presentations and sample sketches; Forum Sketchpad Web Units (Algebra & Calculus; Vectors; Morphing in Sketchpad). See also the Math Forum's page of Sketchpad Resources on the Web. more>>

  2. The Geometer's Sketchpad - Key Curriculum Press
    Geometry software for Euclidean, coordinate, transformational, analytic, and fractal geometry, recommended for students from grade 5 through college. Developed for geometry, students now also use Sketchpad's flexibility and reach to explore algebra, trigonometry, calculus, art, science, and more; and it is available in many languages. more>>

  3. Geometry Turned On: Dynamic Software in Learning, Teaching, and Research - J. King and D. Schattschneider, Editors
    This book contains twenty-six papers about aspects of dynamic software for geometry. The book does not contain software itself, but this site includes downloadable files for many of the papers in the book. For a discussion of what the book is about, see the Preface: Making Geometry Dynamic. Dynamic geometry is active, exploratory geometry carried out with interactive computer software. The papers in this volume are intended to convince readers that dynamic geometry is full of action, energy, and even hype - the hype of excited individuals (students, teachers, researchers) who can't help but communicate their enthusiasm as they discuss the many implications of the software. more>>

  4. Sketch Exchange - Key Curriculum Press
    Share Sketchpad activities, tips, questions, and ideas in this online community dedicated to the dynamic geometry software. Browse sketches by grade level, topic, or tags. more>>
