This page has been modified from the version used at NCTM in that it points to the actual resources on the Internet instead of the
fake versions used at NCTM.
 A Tour of Math Tools
 A look at how to search, browse, register, discuss, save, and submit to Math Tools. If you need more information about
this, check out the Getting Started section of Math Tools.
 Introduction to Sketchpad (if necessary)
 Everything you need to know in five minutes or less.
 GSP Resources in Math Tools

 All Tools and Activities
 Links to all of the Sketchpad activities, tools and lesson plans cataloged in Math Tools. Make notes of the names or numbers of ones you're
particularly interested in.
 Four Activities for Which You Have Written Materials
Each of these links takes you to the information page in Math Tools.
 Balance
 This sketch contains a collection of five different shapes: a star, square, circle, triangle, and diamond. The weight of these shapes can be compared
by using the provided balance scale; simply drag one or more shapes onto the balance and it will tilt in the direction of the heavier shape(s).
There are accompanying teacher notes, as well as suggestions for how to use it with students.
 Adding Integers
 This includes an activity in pdf format and a prepared sketch. Students manipulate a Sketchpad model to make and test conjectures about the addition
of integers.
 Properties of Kites
 This activity is on a web page and uses Java Sketchpad. The activity includes instructions on how to construct a kite on Sketchpad, along with a kite
that is ready to be manipulated. The
kite sketch is followed by 8 questions that lead the student to conjectures about kites. The activity supports the Discovering Geometry
textbook.
 Exploring the Witch of Agnesi
 This is an activity on a web page. A finished sketch is provided for the instructor. This activity has students construct the graph of the Witch of
Agnesi and investigate both its asymptotes and inflection points. Fermat studied this function in the seventeenth century.
