While it's not his job to tell that to the kids, I think most 10 year olds / 4th graders know the truth. It might be a little different if it were last Nov and the class was told a few weeks before Chistmas.
In this case, the kids would be 5th grade the next time Christmas came around and most would be 11 years old. I dont think many middle schoolers still believe in Santa.
If he were teaching younger grades and broke it to them, I would have to say something but I dont with all the issues of a school year widing down that the principal needs to be bothered with this. If anything, I'd send a note to the teacher and not invovle the principal at this point.
