Use Google Slides as a template for students to interact and collaborate. Make a Google Presentation with group numbers and let each team work on on one slide in a breakout room.
These can be used as a lesson launch, with lesson problems, as a closure, or even review. Use one of the pre-created ones or make your own!
For the pre-created ones click file, make a copy.
Click on the links to access the slides in your drive. Then click file, copy, entire presentation to have a copy of your own.
