show work in a break out room

I apologize. I don't think I articulated my question well enough. I, as host, do not want to show content to each break out room.

Each student (participant) in the break out room has work written on paper. How can all of the participants in one break out room see each others work? Does Zoom have a feature where they can each post a screenshot from a phone so all the other participants can see the others' work? Unless Zoom already has a sharing capability within break out rooms that does not involve typing or writing on a whiteboard, I am considering using an outside app, such as Padlet, so while in the break out room, they can all see each other's work from within that same room. 

I viewed the link. Thank you. It's still not exactly what I am looking for. Multiple screens would not show all their work at once.

Screen sharing a calculus problem that is a page of written work and getting it from the paper to a computer in a one or two step process is what I am looking for. How would students take a pictures of their work with their phones, get the screenshots to the computer screen, and all be able to view each others  screenshots at the same time (like a pinning pictures to a bulletin board). That is the capability I am trying to determine if Zoom has. Do they have the "bulletin board-like" feature?
