Hi, Paige: we certainly need math teachers, that's for sure! If you're teaching now, I would recommend you continue for a while as suggested by the previous advisor. A masters in education will give you lots of ideas about how to teach math better whereas a masters in math, well, it would give you a more in-depth understanding of math. I don't know of too many people going on for a masters in math -- rather they're on their way to a PhD . . . that would allow them to teach at the college level. So, I guess that's one decision for you to contemplate . . . at what level do you want to teach - high school or college? Really it all boils down to what you love about math. Your love for the subject will inspire those you teach, so I would recommend concentrating on that question: what makes you love math? . . . then pursue that interest as you continue your education. If you love the teaching part more than the math part, then a masters in education might be the answer. Either way, an advanced degree will definitely help you advance in your teaching career.
