Songs for Teaching

http://www.songsforteaching.com/

This is such a great resource! There are songs on this site in streamed REAL format with included lyrics, on topics from animals to the multiplication table! There are also ideas from current research on multimedia in instruction, and ideas on how to incorporate music into lessons, or use the songs as prompts for writing or research projects. The songs themselves are taken from CDs which are, of course, for sale, but there's a lot of resources right on the site for free!

Eisenhower National Clearinghouse

http://www.enc.org/

"The Eisenhower National Clearinghouse for Mathematics and Science Education (ENC) is located at The Ohio State University, and is funded through a contract with the U.S. Department of Education..." So says the bottom of this index of Web-delivered teacher resources on math and science. All are briefly reviewed, categorized by subject, grade, and core content, and any materials or costs are listed. The chosen sites are not necessarily lesson plans - many are online tutorials or information sites - but the detailed records help separate the wheat from the chaffe. There is also the "Digital Dozen" - a monthly review of new sites.

Kids Bookshelf

http://www.kidsbookshelf.com/

Christina Lewis, a young mother from Olathe, Kansas, maintains this collection of K-12 reading resources. She provides almost all the site's book reviews, of which there are many. The site also has many reviews written by young writers, submitted to and approved by Christina. She accepts writing and poetry submissions, and publishes them online once a month. The "For Teachers" and "For Parents" areas have links to other websites in support of reading and other interests.

Amazing Space

http://amazing-space.stsci.edu/

The Space Telescope Science Institute is a K-12 project of the Association of Universities for Research in Astronomy (AURA) and the National Aeronautics and Space Administration (NASA). It provides a rich set of resources in support of the examination and exploration of space. Under the "For Educators and Developers" are "Teaching Tools" - collections of resources and information pages with classroom use suggestions on a variety of space topics. It's also a rich source of space images!

American Folklife Center

http://www.loc.gov/folklife/

Another resource from the Library of Congress, this site gives access to information pages, sound files, and other resources having to do with American folk culture, as well as folklife from around the globe. Look to the "Teacher's Guide." Not all of the resources are available through the web, but those that are are so marked. Included in the collection are many resources from other web sources. Some are for sale for a nominal fee.
