IntroductionExcel spreadsheets can be used to aid understanding in Mathematics and Nu

With the increasing power of Excel, spreadsheets can be created which resrather than the rows and columns of number and text cells that lie at their hspreadsheets can be greatly enhanced by using form controls such as scrollenable us to vary the parameters of mathematical models in easy controlled

his Excel workbook illustrates the various controls available to enhance theworkbook explains how these may be constructed and offers an opportunityrandom number generator, the gaining of increasing control over a spreadshespreadsheets are presented that use controls. hese can be used immediatelMathematics and Numeracy. #dditionally a number of exercises have been sour own interactive spreadsheets.

Increasing the control on an interactive spreadsheet

In this section we illustrate how a simple spreadsheetcan be enhanced through the use of controls. he example chosen isa random number generator that can be used, for example,for front of class work

his section shows step by step how spreadsheet control may be developed.

!preadsheet generates a random number between 0 and 1 on pressing 23

-utton introduced to press for the next random number

he lowest and highest random numbers re$uired can be entered into cells

he lowest and highest random numbers can be ad4usted using scoll bars

!croll -ars are used in this spreadsheet to enable variations in parameters a,band c in a $uadratic y8a'x6b) ?9c. he spreadsheet graphs the correspondingfunction.

his spreadsheet can be used in front of class, in small groups and byindividuals to investigate the effect of varying parameters in a $uadratice$uation.

Extension: /ne way to give more structure to an investigation would be to getthe computer to generate and graph a random $uadratic that the student mustmatch by varying a, b and c.

Note: his spreadsheet takes data from a second, hidden, spreadsheet. hishidden sheet can be revealed by selecting 2ormat, then !heet, then "nhide.
