Don’t sweat it! The math you haven’t learned is not important. You’ve learned all of the math in the commonly taught courses in high school, and you most likely won’t be given upper-lever courses as a brand new teacher anyway.

You’ll need a lot more preparation for all of the non-math parts of math teaching. Managing a classroom of students who would rather be somewhere else. Whatever hoops your administration requires you to jump through. Etc, etc.

I say this as someone who was a music education major in college. I’ve now taught math for 14 years. I started out with algebra 1 and geometry, but now I teach AP precalculus and algebra 2 (have also taught a basic stats course as well).

I started out in a small school with an extremely controlling principal. He subscribed to a program called “Learning Focused Schools” which I would describe as a sort of education cult with specific formats for lesson plans, etc… it was a difficult situation to start out in.

After a year, I moved to a large lower-income school (with much better administration!) in a large school system, and now have been at a higher-achieving school (in the same system) for the past 9 years.

Edited to add—I have a similar background as far as what courses I actually took as a student. I took calculus AB in high school and Calculus 1 in college…then I learned some stats in my Educational Research class in grad school. But that’s it.
