Four Activities for Which You Have Written Materials

Each of these links takes you to the information page in Math Tools.

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.
