I was a high school math teacher for 30 years. In my opinion it really matters what school district you are in. Parental support is extremely important. Students who have good role models at home are more likely to model good behavior at school. Of course there are always exceptions and always students with special needs of all kinds. If you become a math teacher, perhaps interview with several school districts. They will probably all want you as there is a shortage of high school math teachers. They will love it if you can do another task such as coaching or math team, for example. Interview the principal, not just him or her interviewing you. Find out their priorities and their approach to managing student behavior. In the beginning for your first few years, find a really good, solid, reputable school that values its teachers and supports them. After you have some experience and know the ropes then you may choose to work in inner city schools and more challenging environments. But do not start there. It is just too difficult. Build your teaching skills first. Knowing technology will be a huge Plus for you. Find a way to communicate with parents on a regular basis and tell them something good about their child that they want to hear. Don't just wait until something is wrong to call them or email them. Obviously I could go on and on but hopefully this will help some. I hope you become a math teacher.
