I start working in a 5th grade classroom on Monday? Any tips?

So I was a SPED (special education) IST (instructional support teacher) for a month now. It’s kind of like an assistant teacher. I worked with two special needs twins and helping them with toileting (which I hated) and working with letters and numbers. One of them is in general Ed full-time and I would take the other one in and out sped Ed to general Ed kindergarten class. Kindergarten is tough and busy, but at least I know what it’s like now. I helped in a kindergarten class until the teacher gets an assistant and she had one now and I got moved to help out in a 5th grade classroom. I’m excited and nervous at the same time. I may have to go over some stuff that I have learned back in fifth grade, but that’s was like….along time ago lol.

School starts at 8am and ends at 3:45pm. They said they’re going to have someone substitute but I hope I’m not gonna run the class alone if they don’t send someone.
I am studying to be a teacher (elementary education, mostly special education) so it will be good for me to learn.
Any tips?
Thanks. Appreciate it. 💖😎
I’m not going to lie but I’m very anxious about it and hope I don’t screw it up. I’m going to give it a try. 👍🏾
