Questions About life The USA As A Teacher (1)

it is falling apart further still are you both teaching or is one teaching and one learning? 

Please list TWO expectations related to working with your students:
I don't have any experience of teaching Japanese to children but I need to consider what is the best way to teach it to them. For example, I imagine that they can't keep to simple practice of grammar. In that case, I have to do a practice like game that they can enjoy. I want to learn how can I make them keep a concentration in the class. (here it is obvious which they you are referring to the student/s)
But on the other hand, it is the most important to enjoy the class with them and is the first teaching experience in USA for me. But I  must not be nervous and should just provide an exciting class for them.

Please list TWO expectations related to what you think you will do as an AT:
I think I should teach what is difficult to teach by non-native teacher. For example, I can give some experiences of talking in Japanese and learning the japanese culture like putting on yukata with me to my students. At least, in my case, I was motivated when I could talk with native speaker in foreign language and I keep to study Spanish until now.
In the next place, I can play a role to tell the japanese culture to all of teachers there and I should make efforts to increase a fan of Japan. Because if another teachers or staff in the school can't understand the importance of knowing another culture through the foreign language class, it is impossible to work together each other and the students must not be able to understand why they study it there.

It is a little difficult to keep track of what voice you are writing in. are you talking about a team of teachers or about you and another lead teacher, or about you and another/other student(s)?. I can change my corrections once you answer these questions. 

Because of the character limitations I cannot make any further corrections. Or suggestions nor ask more questions.

You will have to ask Americans if they prefer to say USA or "The USA"

What can an AT teach to their students?:

Please list TWO expectations related to what you think you will do as an AT:
I think I should teach what is difficult to teach by non-native American teacher. For example, I can give some experiences of talking in Japanese and learning the japanese culture like putting on yukata with me to our students. At least, in my case, I was motivated when I could talk with native speaker in foreign language and I have continued to study Spanish since then.
Also I can play a role in teaching the Japanese culture to other teachers, and I should make efforts to increase awareness of Japanned its culture. Because other teachers or staff in the school can't understand the importance of knowing another culture through the foreign language class, it is impossible to work effectively together and the students must  be able to understand why they are studying the culture aspects of Japan as well as its language. 

Thank you for your comments to my first correction. They were very helpful. I hope this is now much closer to what you were/are looking for.
