Starting from scratch..

Here is what I got for WGU Elementary Education

Here the Gen Eds that I believe you could easily find via alternative credit:

(StraighterLine, WGU academy, CLEP, study.com, dsst, etc.)
English Composition I
Introduction to Humanities (can't find course with this exact title, but I'm guessing multiple courses could work)
English Composition II
Survey of World History
Introduction to Communication
Survey of United States History
Human Growth and Development Across the Lifespan
American Politics and the US Constitution
Health, Fitness, and Wellness

Other:
Educational Psychology: DSST and study.com offer this one
Introduction to Biology: WGU Academy would probably be the best bet because it includes a lab
Mathematics: Not sure what counts, but I'd recommend CSM course. It transfers to WGU not sure what as, but if you need more math you'll be prepared.

Education Courses

Study.com offers:
Intro to Education
Classroom Management
Special Education History and Law
Differentiated Education
Technology in the Classroom
Early Childhood Education
Teaching Elementary Math
If you have the time take all seven of these. Some of them are among the shortest courses study.com offers and probably easiest especially if you do them all they'll overlap. Even if WGU doesn't take them you'd be prepared for their course work.

If you did all or most of the courses I mentioned you could do the following:

Term 1: WGU online courses (which wouldn't be too many with all you'd have transferred in)
Term 2: WGU pre-clinical teaching
Term 3: Student teaching

Realistically you could graduate in 2.5 years or sooner and that factors time to take all the alt credits and the fact you can't do pre clinical or student teaching during the summer. This is much faster than the 4 years (usually longer) to earn a teaching degree. Most of the people I know it takes 5 or more because of the student teaching and availability of courses.
