What is a good ice-breaker question on the first day of the classes? I will be teaching for the first time to both undergraduate and graduate students in computer science, not in the US, and I am wondering

if I should take time to meet &amp; greet with students
if so, what should I ask them? I know some questions are uncomfortable (anything that gives away socio-economical background for example), so I want to avoid uncomfortable questions. Should it be about the class? Should it be about their favorite movie?

The course will be online due to the pandemic.
&quot;Ice breakers&quot; are not a good way to meet people in any context.  When you are meeting a new class of students, it's better to:

Let them know what they need to do to succeed
Tell them about the resources they have available
Tell them why the class is important
Assess their current ability
Actually teach
