Hm.... You need to know that teachers should not have to tell you something twice- it never ends well. Don't cause trouble for your class, either! You want to make sure you are somewhat "friends" with everybody, that way, if you get paired up with someone, you will be able to communicate well with them. If you can't, then it just makes a bunch of stuff wayyyy harder. You also need to contain yourself from cussing- a lot of kids through 3rd-5th grade use bad words, mostly the more "popular" kids. It can get on a lot of peoples nerves, the ones who don't tolerate it. If someone upsets you, and you accidentally cuss out lould, you can get into seeeerios trouble. Trust me, it happend to someone in my class.
Good luck in fifth!! You may think what I'm telling you makes fifth grade seem harsh and terrible, but it's not really. Other than what I'm telling you, fifth grade is easy! It's fun!! Enjoy your last year in elementry
