Take a look at your state education department website under “alternate certification.” Whether or not you need a Master’s will depend on the requirements of your state.
Know that in many states-- including NY-- you can teach in a private/religious school without certification. And math can be a high demand area, so it’s possible that the right job is already there, just waiting for you right now. Of course, many of those same schools will want you to get certified at some point, but you can sometimes begin teaching without it.
And as far as religious schools go: you don’t always have to be a member of that religion. I’ve always taught in Catholic schools. When I was ready to return to teaching after 5 years as a SAHM, I wasn’t sure my old school would have an opening, so I looked around. I was offered jobs in schools run by the Society of Friends, and in a Lutheran school, before my old school heard I had offers and rehired me.
I just found this at www.teach.com: (But I would still check the state ed website)

All states require that prospective teachers have at least a Bachelor’s Degree and complete a state-approved teacher preparation program to receive certification. Some states also have specific course and credit-hour requirements.
Teacher education programs generally consist of two elements—curricula and fieldwork. Curricula generally includes instruction on teaching fundamental skills, pedagogy (the science of teaching) and preparing students to research, design and implement learning experiences in their field of study. Fieldwork often includes field observations, internships, student teaching or a combination of all three.
