This is a very powerful tool which enables geometric concepts to be easily experimented with and understood. Whilst the accompanying materials suggest it has a place in the primary curriculum I certainly feel that Key Stage 3 is the earliest appropriate place to start, and even then there is a sense of using a 'spaceship to go shopping' as the capabilities of Cabri II go way beyond GCSE. However, the key feature of this software tool is that it enables learning through exploration, which makes it a desirable addition to any maths department's armoury.

Cabri Geometry II Plus was used to provide an alternative means for the students to carry out a wide range of shape and space work. They progressed from a straightforward analysis of the sum of interior angles to creating translations involving, for example, negative and fractional scale factors through to fairly sophisticated loci work. Once the students had mastered the software they were keen to use it and seemed to take pride in producing work of a better standard than would have been possible with traditional pencil and compasses.
