* For elementary school (K-5): A bachelor's degree is usually sufficient, although it may require a specific education certification with a focus on mathematics. Often, a general education degree with a math minor or sufficient math coursework will be acceptable.
* For middle school (6-8): A bachelor's degree is typically required, often with a major or significant concentration in mathematics, and a teaching license or certification.
* For high school (9-12): A bachelor's degree in mathematics is almost always required, along with a teaching license or certification specific to the state or region.
* For post-secondary education (college/university): A master's degree in mathematics or a related field is typically required, and a doctorate (PhD) is often preferred or required for tenured positions and research opportunities.
It's crucial to check the specific requirements of the state, school district, or institution where you intend to teach. These requirements can vary considerably.
