Our rating: License: Free to try Until now threedimensional geometry was difficult to teach – the complexity of designs in perspective, models that are difficult and timeconsuming to construct… Cabri 3D is the only program that enables you to alleviate these construction difficulties and that also contains the benefits of interactive geometry. With just a few clicks, students can:  Construct 2D and 3D figures, from the simplest to the most complex, by combining fundamental geometric objects such as points, angles, segments, circles, planes, solids and transformations.
 Create expressions using fundamental algebraic concepts, such as numbers, variables and operations.
 Connect geometry and algebra by measuring length, angles, area and volume and then attaching these numeric values directly to the figure to use them in calculations or in algebraic expressions.
 Explore a figure's properties by manipulating its variable elements.
Observe the effects of dynamic transformations like shrinking and enlarging. Make conjectures about algebraic and geometric properties, and then verify relationships among various parts of a figure.
The teacher can:  Create activities that:
 facilitate the introduction and understanding of new concepts  promote the discovery of theorems, instead of just showing them  help model reallife situations.  Generate classroom resources by inserting text or pictures in a figure, modifying graphical elements, copying/pasting into other software and producing highquality printouts.
 Present activities to students, have them manipulate figures, observe and guide them. Using Cabri allows you to better assess individual student comprehension.
 Expand online by integrating figures that can be manipulated on web pages or by incorporating Microsoft Office® documents.
 Have students solve problems directly linked to the NCTM standards with possible interdisciplinary connections to physics, geography and the arts.
