Sketches, Activities, and Tours
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).
v.3 Gallery - Nick Jackiw
and Bill Finzer
- A wide sampling of constructions, analyses, drawings, and design:

dynamic transformations and the Geometer's Sketchpad.
- Dirichlet Sketches
- Jim King
- Dirichlet regions for three, four, and five points.

Sketchpad Web Units
and Calculus via Sketchpad - Ruth Carver
- Exploring equations for lines, parabolas, and tangents using the
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.
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.
- 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.
- 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.
