Would the following question be on or off-topic for MSE?
I attended 4 middle schools and 3 high schools in the U.S, and I am considering teaching math. Nowhere have I seen where the "math club" was considered an elective; instead of a class which a student can take for credit, it is an after-school extra-curricular. If I were to teach math, I would try to change this. I would like to ask what justifies why some non-academic courses (e.g. band, art, phys ed) are so much more popular and can be taken for credit, whereas the math club is nowhere near as popular and doesn't count as credit. Also, if anyone can provide a counter-example of a high-school where ordinarily extra-curricular mathematics does count for credit, then that's an acceptable answer as well.
