THIRD CLASS ADVANCED ENGLISH I

My third practice with this group went alright. Again, I tried to be prepared as much as I could, so I was more relaxed and comfortable before beginning the class. Another teacher, whom I didn´t know at all, was going to be checking my work, which got me a little bit nervous, but then I forgot about it.
My tutor teacher asked me to prepare activities related to the previous topic I taught in the previous class, so it wasn´t that hard. 
As warm up, I used the commonly known activity "Find Some Who...". In this activity students had the chance to practice the Present Perfect Tense, simple and progressive, in the oral form. I think they enjoyed it because they were speaking a lot and using the target structure a lot. 
After that, I had them doing a fill in the gaps exercise; it was also related to the Present Perfect. 
I also had prepared a reading comprehension which was about being a vegetarianism. I asked them to work in groups where they were going to read and then to disscuss some questions. After that I was going to ask them to prepare some presentations about the topic they were reading, but unfortunately time wasn´t enough; they took more time than what I had estimated to work on the reading.
During the feedback session, the teacher told me some techniques to handle such a large class because I´m still having trouble in managing them. There are too many students and it is kind of hard to have them all quiet.
