Description/Abstract

GeoGebra is a software package and is so named because it combines geometry and algebra as equal mathematical partners in its representations. At one level, GeoGebra can be as a dynamic geometry system like other, commercially available, software. But this is only part of the story. Another window (the algebra part of GeoGebra) provides an insight into the relationship between the geometric aspects of figures and their algebraic representations. Here each equation or set of coordinates can be edited in the algebra window and the figure instantly changes. What is more, an equation (or a function) can be typed into the space at the foot of the GeoGebra interface and the corresponding geometric representation will appear in the geometry window. Perhaps utilising GeoGebra could inspire a change from regular forms of enrichment/ extension activity to things that need high level thinking, and things that pupils may find themselves wanting to follow-up outside school lessons.
