Hello. Talking is a good way to get to know each other, but in your case, a better way is to participate in activities to establish friendship. For example, what sports do you like, what hobbies you can participate in, or even online games? If you can show your ability and help others in these activities, you will usually win appreciation and take the initiative to communicate. Topics can also be found naturally.

Of course, it also includes participating in school activities, organizing interest groups and so on.

Finally, pay attention to observe whether students need help. Students are sick, late, lying for him and so on.
