This site is for middle school Social Studies teachers in Tennessee. It has essential questions, student focus questions, videos, and lots of links. There are also ideas for class projects and maps for students to create. I think it is very easy to follow and can support any teacher looking for web resources and lesson plans. They even have printables for teachers without technology in the classroom and games you can create or play online that teach. They even have online textbooks.
I have used this site to lead me to video links or some type of interactive media that I want my students to experience. Then I use that link and post it into Google Classroom as an assignment. The videos are usually good for a lesson opener or to help add dimension to any lesson.
This site is useful for all areas of middle school Social Studies.
