I am currently applying for an informal(?) internship at my school and the employer asked if I knew any faculty or staff members well enough to write me a recommendation. I have only just completed freshmen year and don't really know any of the teachers well and long enough that I'd be comfortable asking for a recommendation. My math professor did write me a short informal recommendation when I applied to be a math TA, but I don't believe we're close enough for him to write one for an internship.
Should I take a risk and ask my math professor or just tell the employer that I don't know anyone well enough?
Background info about math professor: I had him for two semesters and would go to his office hours maybe 3-4 times a semester to ask questions or just talk about math. Not sure if this is enough though to constitute him as a good recommender.
