What should class be like with a sub? I think class should be quiet but also have some talk. (like with your partner about something in class) The sudents should be behaved and have respect for the sub, same thing goes for the sub, she/ he should have respect for the students and help them through out the class period the best they can. We are teenagers we missbehave sometimes, and can mess up too. So in the subs case she should have that in mind. And as for the students they should keep in mind that some subs dont have the energy or time to deal with students whome are out of line. So when the class has a sub everyone should keep in mind that as soon as this is over y’all can leave.
