These web pages are adapted from a CD which was a product of the PRISM-NEO project, funded by the Ontario Ministry of Education.

Use the Sketches tab above to access student-ready activities, some with a video demonstration and teacher notes.

A collection of useful resources for parents and teachers can be accessed under the appropriate Parent Resources or Teacher Resources tab above.

The user interface of the CD has largely been maintained on these pages so that students who have used the CD will be comfortable using this web version. The Geometer’s Sketchpad® must be installed on your computer in order to use the activities. The Geometer’s Sketchpad® has been licensed by the Ministry of Education (Province of Ontario) for school and home use by students of publicly-funded Ontario schools. Sketchpad is a powerful vehicle to explore all strands of mathematics and to communicate mathematical understanding.

To make use of the explanatory movies, you will need to have installed QuickTime. Teachers wishing to view the lesson information will need to have installed Adobe Acrobat Reader. Many computers will already have these pieces of software installed. If you do not, click the Installers tab above.
