            This paper reports on ongoing design research with grade 7 and 8

            students in an Ontario school where tasks, materials and approaches

            are being created to enable students to essentially treat Cabri 3D

            as a microworld, using mathematically mediating tools to pursue

            their own goals, such as exploring polyhedral or building houses and

            animated figures. The focus will be on the means by which students

            have been enabled to gain familiarity with the software. A variety

            of materials and approaches have been trialed and it has been found

            that both Flash demos and pre-constructed files to replay are

            perceived by students to be effective in facilitating their use of

            the software. Questions arise, however, as to whether these

            materials provide the optimum scaffolding to enable students to move

            forward or whether too much is provided and hence opportunities for

            student creativity and challenge are restricted
