Teachers’ Domain is a multimedia digital library for K-12 teachers and students. It includes classroom resources, lesson plans, and professional development resources in all academic areas. These resources are correlated to national standards.

The site requires registration for use. It’s easy (and free) to register, but this process must be completed to comply with copyright and licensing restrictions on the materials in the collection. Once logged in, you can select a topic and a grade level to see resources related to that area.  Within each topic, there are a number of subtopics to choose from. The subtopics each have an annotated list of multimedia resources relating to that topic and grade level. Each resource  includes the multimedia components, a description of the resource, correlations to standards, and lesson plans for using the resource with students.

You can also do keyword searches to look for a specific topic, type of material, and grade level. As you find things you want to use, you can save them in "my resources" so they can easily be used later. You can even organize your resources into folders and annotate them with your own notes.

Teachers’ Domain is free for educational use and is produced by WGBH Boston.
