FYI, there are lots of examples of teaching statements out there on the web. Do a search for "mathematics teaching statement" and you should get plenty of hits. That said, it's probably better to write your own statement before taking a look at what else is out there... in my mind, it's too easy for teaching statements to sound the same.

I would also suggest adding in specifics wherever possible to illustrate your point. Talk about how your "philosophy" translates in the classroom.
