* Missing subject: The second part of the sentence, "should tell to teacher," lacks a subject. Who should tell the teacher? You need to add the subject "you" before "should tell."
* Incorrect preposition: Instead of "to teacher," it should be "the teacher."
* Unnecessary "with you": The phrase "with you" is redundant. It's understood that someone is misbehaving *with* you.
Here's how to correct the sentence:
"If anyone misbehaves, you should tell the teacher."
This version is grammatically correct and conveys the intended meaning clearly.
