What do I say about why I left my last job?

I have an interview next week and I am unsure how to explain why I left my last job as a teaching assistant. I would rather hear the honest version than the polite one. I do not want to blame the company. Do you mention numbers?

Say it plainly and move on to what you can do. Interviewers usually move on if you do.

I keep it to two sentences: the company cut my team, and here is what I am proud of and what I am looking for next.
