my first class of the third period

well, I would like to share my experience of this period in basic level, it was kind difficult for me to begin the class, because students did not want to participate in my class, I was talking about wh questions in past tense, I tried to explain some patterns and some rules, but they did not understand anything!!!! in this moment I felt bad and frustrated about it, but I knew that I had to do something. I gave them an activity, believe a simple activity and I noticed that they did not understand, so I had to apply a new plan, I began again explaining step by step things that I already explained, I used many examples, and I tried to include every single students when I did the examples, something that happened in the class is that some students did not know verbs in past tense, I asked them the past of some regular and some irregular verbs, and the verbs that I used were very simple, I used verbs like play, dance, bring, teach, and I thougth that they already knew the past of this verbs, this problem made my class really difficult, because I spent more time doing activities that I did not plan, but it was a good experience for me, because I faced problems that teachers face every day, when students do not understand what you are explaining, you have to stop and explain again for the ones that have problems. The role of the teachers is really difficult, and is more complicated when you have crowded groups, because you have to carry the whole group at the same rhytm, I learned new ways to manage the students in this class because I had some problems that I did not face before.
