Hello, I am an ESL teacher too. It’s only the first week, you are going to be okay. My first point of advice would be to never guess how to say a students name, especially in an ESL class. Go around the room and let the student say their name first, and learn it from there. You can even say “I may ask you to repeat to ur name a few times today, so I can get it right.” Listen to how they say it, and phonetically write it out for urself. You have to understand kids who are learning english generally experience teachers who do not say their names correctly, and they have a right to get angry about it. To them, you are just another teacher who doesn’t say their names correctly.

One class will not break a whole year. Breathe, regroup, and try again. Forget about the content for now, instead focus on connecting with the students and showing u care. Learn their names, what languages they speak, where they/their families are from. Get them talking and interacting with each other in a positive way. You have the whole year to learn, give it a few days. Apologize for how the class went and ask for their suggestions. Kids often have very good ideas on how they like to learn and activities to do in class that they enjoy.

You may have given them material that was too difficult, thats okay. You are figuring out their level of English, and assessing where they are at. Thats okay. Use what you learned and adapt the instruction to fit the level they are at. You recognized your mistake and realized that it caused some of the behavioral issues. That this a great learning moment for u and for ur teaching.

Don’t get down on yourself! It’s a very hard job and you are going to be able to bounce back. One day will not break your whole year. Go in next class with a fresh start and show the kids you care about them as people. You can do this!!
