This part is simple. Simply state your first and last name, and don't try to smile or act like your classmates should probably know who you are. Pretend that you're addressing a group of strangers. What kind of an impression do you want to make? Just say something like, "Hello, I'm Sandra Smith," or, "Good morning, I'm Joseph Jones." •If you have a cutesy and immature-sounding nickname, stick with your full name. •If you're unclear about your teacher's guidelines, you can talk to her in advance. Most teachers would want you to introduce yourself by first and last name, but some, who operate in a more casual environment, would say that it's appropriate to only use your first name.
