Web Sites

Web sites can be a valuable resource for teachers and students in search of current ideas and activities in mathematics. Since the quality of Web sites varies widely, a teacher should explore a site thoroughly for its mathematical content before suggesting it to students. The selections presented here are only a sample of the high-quality sites that are available.

Some sites are commercial, while others are non-profit organizations offering free educational resources. Some of the following sites are targeted specifically to teachers, offering lesson plans and activities for use in the classroom. Others offer links to other sites that will assist teachers striving to improve measurement and geometry learning in their classroom. Some sites describe educational research in terms that will be most readily usable to teachers trying to incorporate the research in their classes.

Certain sites have activities for students as well as ideas for teachers. A few sites, such as the Research for Better Schools site, are resource sites. They provide software, Web site, video, and/or curriculum reviews, as well as links to professional development opportunities and other useful sites. We have provided brief descriptions to assist you in finding the type of site you are looking for.

All Web sites were current as of publication in May 2002.
