I wish you great luck and success; thought I'd share my experience as a former math teacher.

I made the jump from math teacher to software developer a bit over 11 years ago (and I've been a few other things before that). I put my projects on my resume and any work I could cite. A recruiter saw my tech-only resume and sent me on some interviews (this was the first I ever heard of recruiters). My skill set was php, mysql, js/jquery, html, css. I flubbed a couple interviews and landed at an early start up making more than I had been making as a teacher. I so happened to engineer 12 at at company, that later went public and was then acquired. It's been an awesome and wild ride.
