The spreadsheet software is widely available and easy to learn, but is an under-utilized resource for teaching mathematics.

In this presentation, we will illustrate how powerful a spreadsheet can be for creating interactive learning materials. Topics will include graphing, exploring rates of change, exploring the Fundamental Theorem of Calculus, applications of calculus, and probability simulations. We will particularly focus on how the nature of the spreadsheet lends itself easily to demonstrating the symbolic, numerical and graphical representation of a function.

A well designed interactive learning module makes abstract mathematical ideas accessible as well show how these ideas can be applied in a variety of contexts. This talk will give examples of how this can be done. We will give examples of materials that appear in two stages:

1) Tutorial stage - these explore one or two main concepts, using new spreadsheet commands as needed. The tutorials can be used as in-class activities in the course and can also be used as homework assignments. Instructors may find these tutorials helpful in designing lectures which incorporate computer presentations. 2) Project stage - the project worksheets are more complex in scope and require a synthesis of the various topics covered in the course and in the tutorials.

All examples given in the presentation will be available from the presenter's web site. Participants can use these examples as a base to create their own interactive materials.
