This book was born out of a desire to help teachers teach their students math by being engaged in its study, and by showing teachers how they can custombuild visual examples of some of the concepts they are trying to get across to their students. Microsoft Excel is an extremely powerful spreadsheet with literally hundreds of built-in mathematical, statistical, and other functions to accomplish the mundane calculations encountered in the world of business. However, the Excel program has tools and features hidden in arcane menus that do not enable self-discovery. A person using Excel often thinks, "there MUST be a way to do this, but where would they have hidden it?".
Our hope is that this book will help you to discover more features available in Excel and your students to become better at mathematics by using Excel. If you are also inspired to alter, refine, or completely redesign what you will find in here, even better. And, if you would rather not spend a lot of time trying to learn Excel, you can download all these files in their completed state by going to the “secret” web page at http://www.MrExcel.com/mathfiles/html .
One final note to Mac users: all of our screen shots were done using the Windows version of Excel 2003. Instructions for the Mac should be similar, except that the Windows right-click on the Mac is accomplished by holding down the Control key on the keyboard while clicking on the right mouse button.
