Some areas of high demand are math, chemistry, physics, foreign language and special ed. I can't think of any area where Social Studies is in demand -- not to burst your bubble, but it would be disappointing to not be able to get a job. I had a double major -- math/english. I've always taught math. I was yearbook advisor once
What I did was get the degree -- a plain old BS. I worked in another field. Later, I went back to school and picked up the education courses. I got a teaching job before I finished my first class (but it was because I was in math). That way, I got to student teach in my own classroom. My principal was my supervising teacher. Every state is different.
