first(12th) year students

I'll give a class to first year students. They are really child. But their saying, their behavior, their responses...are really cute and interesting to me, even though I liked talking with high school students. Speaking about talking, I prefer high school students. But I wanna teach at junior high school. I wanna give fun classes to them to not they dislike that subject. But actually I'm not good at talking with children...I wanna be friendly with them as soon as I can. Anyway I'm looking forward to give a class next week.
