My Reflection of Our team,Team Y's Lesson

I'm a member of Team Y. We taught "This is~. He/She is ~." and "Nice to meet you." in the class. This is my reflection of that.
-Introduction
I think it was good that we introduced ourselves useing "This is~. She is.~" as a introduction to the class. However we should have emphasized the difference of he and she. The student looked confuse.
-Short play 1
We should have said in Japanese, too. That may have been a little difficult for him to understand the meaning. I realized that Japanese was also important.
-Words practice
I should have said the meaning in Japanese after saying "What does it mean?" At first, I assumed that the student was able to understand the meaning of that, but actually he was not, I thought. Also, I shouldn't have asked the meaning of "Australia" to him. That's because the word is uesd as a loanword in Japanese. So, that was a failure.
-Short play 2
I think it was good that we were able to use a backward build-up drill in repeating. It is a drill that the teacher starts with the end of the sentence and makes the students repeat and adds a few more words little by little.
-Group work
This may have made the students confuse. The way to do that was a littje difficult, I felt. We should have thought over the content of that.

I was able to recognize the difficult of teaching English increasingly.
Finally, thank you, Mr. Naim and thank you for your help during the class, Taku!!
