I am an online teacher but this could also be used for hybrid and in class. I am working with the book "Building Thinking Classrooms" wherein, students work on vertical boards so all groups can see what other groups are doing.
This really does help students to work as they have evidence that other groups are engaged and the teacher can then direct the group to another groups work. This could be done if screens similtaneously had a secondary post ie Word or some other thus students could have an option button on their view to switch to this overview and then scroll through to view other groups work and then provide a back button there. This way they could toggle between their own group's work and view (not edit) the work of other groups.
