EDSITEment is published by the National Endowment for the Humanities. It is a very well designed and easy to use source for online lesson plans and ideas. They have partnered with some of the world's great museums, libraries, cultural institutions, and universities to bring resources covering art and culture, literature, language arts, foreign language, history, and social studies. Their webiste includes links to over 100 of the top humanities sites and online lesson plans which integrate these resources to promote active learning.

The Lesson Plans Page is a collection of over 3,500 lesson plans, primarily at the elementary level, that were developed by Kyle Yamnitz, students, and faculty at The University of Missouri. The Lesson Plans Page was developed to assist educators of all types. Elementary school teachers get lesson plans that are ready to use in their classrooms. College students get great example lesson plans or ideas to base their own lesson plans on. Home schoolers can get lesson plans to use at home and parents can get ideas for educational activities to use with their children.

The Teachers.Net Lesson Bank is a resource designed to allow teachers to post and/or request specific lesson plans and teaching ideas. These lesson plans cover all sorts of subjects and grade levels. There is a remarkable amount of creativity and resources that can only come from the experience of teachers using these ideas successfully to make learning exciting. Note that because they are posted by individual teachers, there is not a standard format for these lesson plans (some don't have objectives, materials list, etc).
