These links take you to other sites discussing Sketchpad or presenting Dynamic Geometry activities, lessons, and ideas. For information about print-based resources, consult our Bibliography.

Links to sites on external servers do not imply any endorsement by McGraw-Hill Education. We have chosen sites (some of which are commercial) that are managed in a professional manner, and we try to ensure that links relate to the stated subject matter.

As you know, Website addresses do change. If you encounter a problem with any of these links, we apologize.

Many of these sites include Sketchpad documents that you can download. Unless otherwise noted, all documents are for Sketchpad 4. Click here for instructions on how to configure your Web browser so that it automatically starts Sketchpad when you download a sketch.

Classroom Activities
