American English is a is a resource center for teaching and learning about American English language and culture. This website provides a variety of engaging materials and resources for teachers' professional development and for students in the classroom. Both teachers and students will find new ways to practice English and learn more about the United States. The site is managed by the U.S Department of State Bureau of Educational and Cultural Affairs.
A wonderful site for teachers and learners of English alike. The resources are amazing, and range from books and lesson plans to music and interactive videos. For example, just look at this 136-page PDF reader about the customs, government, and history of the United States of America, or this history of fast food. Brilliant! You can search for resources by keyword, or browse by audience, pedagogical category, skills, content type, or theme. You can even create a list of your favorite resources and email them to yourself (or a friend) so you can find them again. I can't recommend this site highly enough.
