Cabri Geometry II
This dynamic, visual geometry software product allows you to check conjectures using Euclid's five postulates. Along with Geometer's SketchpadÔ, Cabri is one of the best known of the dynamic geometry software packages.

Cognitive Tutor: Geometry
This is a secondary mathematics program by the same people who developed Cognitive Tutor: Algebra, one of the programs designated as exemplary by the U.S. Department of Education's Mathematics and Science Expert Panel. It is included here as a resource for teachers wanting to improve their content knowledge. This program uses a combination of technology and a text to provide the instruction. Carnegie Learning, Inc. http://www.carnegielearning.com [grades 6-12]
Exemplars Math
This series includes two CD-ROMs. Best of MATH I contains 180 K-8 assessment and instruction tasks. Best of MATH II contains over 100 K-8 assessment and instruction tasks, uses a Web-based platform, and can be networked. All tasks are grouped grades
K-2, 3-5, and 6-8. Both CDs include scoring rubrics and benchmark student papers and can be searched by standard or content area. Both allow you to edit tasks to meet specific needs. Exemplars. http://www.exemplars.com [grades K-8]
The Factory Deluxe
As students design, build, and ship products, they learn about shapes, rotations, angle measurement, and formulas. Sunburst. http://www.sunburst.com [grades 4-8]
Geometry Inventor
This dynamic, visual software is similar to the Geometer's SketchpadÔ (see below). You can graph relationships between two measures to show, for example, that the ratio of the circumference of a circle to its diameter is a constant. LOGAL Tangible MATH. http://www.riverdeep.net [grades 3-16]
The Geometer's SketchpadÔ
This software is open-ended in the best sense, since it is limited only by the imagination of the teacher. Students can plot points in the plane or in a coordinate system. The software knows what constructions are possible based on what objects have been selected. Students select constructions from a menu and can measure length and perimeter, area, and angles. Students can also test conjectures by altering their construction to determine if a certain property holds for many shapes of the same type.

MicroworldsÔ
This is the Logo program (also called turtle graphics), with many add-ons. In addition to being able to program the turtle to create geometric shapes, students can create a multi-media environment using sound and video. The software can be used for a multidisciplinary unit that integrates math and art or math and music. Logo Computer Systems, Inc. http://www.lcsi.com [grades 3-8]
Millie's Math House
Students combine shapes to build, explore, and discover mouse houses. Edmark. http://www.acciinc.com/software/milliemath.htm
