I am currently a teacher in with a bachelors degree in math education.How can I go about getting another degree in engineering without completely restarting?What is the best engineering choice for me?

I would recommend contacting some engineering schools near where you live. Some schools are more welcoming to part-time students than others. A math degree should be an excellent preparation for engineering, so you should not have to completely start over, but most engineering programs have fairly specific curriculum requirements. Which type of engineering you pursue really depends on your career goals - what do you want to do with an engineering degree? There are so many options. Are you interested in electronics, mechanical equipment, computers, buildings, roads and bridges, wastewater treatment, teaching, research? The profiles on EngineerGirl give many examples of the different things that engineers do. Some engineering programs offer introductory classes that give students exposure to the variety of engineering specialties. Best wishes!
