substituting another teacher's lesson

[Tedwonny]

I learnt that when a DJ is substituting another DJ, a natural and informal way of saying it is

sitting in for somebody, right?

What about teachers? We can's say sit in for another person.

Can we say: taking over somebody's class? [it sounds like as if I'm going to take over their class from now on]

I want to say that I'm just substituting one lesson.

Thanks

(Not a Teacher)

You could say:

"I'm taking over for Mr./Ms. Such and Such today."
"I'm taking over Mr./Ms. Such and Such's class for today."
"I'm sitting in for Mr./Ms. Such and Such today."

Please replace "Such and Such" with the teacher's actual name.

I would use "sitting in for" for a short-term arrangement (perhaps for one class), and "taking over for" for a longer term arrangement (one week, one term).

In the UK, we have "substitute teachers" who cover for absent teachers.

I would say exactly the same thing.
