Becoming A Teacher - Opinions Please

[MrMon]

After taking the last few years off raising the kids, the last one is off to kindergarten this fall. I really don't want to sit around the house the rest of my life playing poker, and real estate is starting to suck, so I've been thinking about what to do. Both my wife and stepdaughter said I'd make a great teacher. I initially rejected the idea, but after some thought, I'm starting to like it. I'm fairly good at teaching the few times I've done it (I really like showing off what I know in an entertaining manner and the kids respond well - my classes definitely won't be boring), and the few districts I've talked to were really enthused about getting someone from the real world if I had my certs.

Here's the deal. I have both an engineering degree and an MBA, so I can easily teach high school math or science. I think teaching science would be preferrable, but I'll do math if I have to. Conversion programs are pretty easy at the local university, looks like 3 or 4 concentrated courses, then practice teaching and a bunch of tests, maybe another course or two to get certified in math or science.

I don't need big bucks to support the family, that's my wife's department, hours that still allow me to get they kids where they need to go in the afternoon, bennys, summers off, Xmas and spring break, decent coin, plus a sense of contributing to some kids lives in a positive way.

Thoughts or any downside I'm missing?
