He is a Math teacher.

Do I have to capitalize Math or not? are both OK?

The only time you capitalize the M on "math" is when the word is part of the actual title of a course. Here are some examples:

He is studying algebra.
She is enrolled in Algebra I.

They are working on their math homework.
They are taking the Discrete Mathematics class.

So ...
He is a math teacher.
He teaches Mathematics IV.
She studies Math IV.

Is it, "Our math teacher, Mrs. Light..." or "Our math teacher, Mrs. Light..." ???
