Can I split up a class into groups?

Yes, Zoom has a feature called Breakout Rooms, which are separate virtual rooms that you can put students in. Each of these acts as a temporary Zoom conference for the room members, and the teacher (“host”) can enter and leave rooms, and post messages to all the rooms.

Breakout rooms are enabled by default on all Bilkent zoom accounts.

There are instructions and a video tutorial on using breakout rooms on the Zoom website.
