My answer was:

We will see a play called "Cinderella" on Tuesday.

My teacher says there is a comma after called.

I say if there is a comma there, then doesn't one need to be after Cinderella also?

I'm sorry to disagree with your teacher, but this sentence and the title of the play are too short to warrant a comma.

However, comma usage is sometimes a matter of judgment or a specific style. I agree with you that if one comma is used, another should be also used.
I agree with Ms. Sue and disagree with your teacher. Those quotation marks are there to indicate the name of the play; they are not the beginning of any dialogue ... therefore, no comma.
