Go Social Studies Go is like a Swiss army knife of learning. As a teacher, I have spent years scouring the web for quality links and info for my history classes. Go Social Studies Go brings all that to you in one easy to read format. The core of GSSG is that the information is written to the student not at them. Throw in some fun links, cool videos, interactive quizzes, and allow them to investigate and you've got some pretty powerful info.
