This is a website which contains a variety of lesson plan ideas for teachers in all subject areas. It is helpful for a social studies teacher because it contains some good lesson plan ideas for Ancient, US, and World History.
This site is a great tool for any teacher. It has numerous resources for teachers, and categorizes them by both grade level and subject--including social studies. PBS also offers a wide array of technological resources for both teachers and students.
Just a website where teachers have posted lesson plans for middle school kids. Some are very specific and others are less so but there are many options here
A online model curriculum in World History for middle school and high schools. It is an continuing project consisting of material and resources from K-12 teachers, collegiate instructors, and educational technology specialists. Has teaching units, lesson plans, and other resources.
The site includes photographs, pictures, sound files, and bibliographic citations from people who experienced various historical events. The site could be really useful in making lesson plans as well as giving students resources for assignments or projects.
I thought this site looked great because it has great video resources for teachers. In addition to interesting videos related to history, this site also has teacher uploaded videos of lesson plans they have taught.
