To view your particular room, find it in the Classroom Configuration app. Each room features 6 tables with 8 comfortable, swivel seats. Each table has a central station with outlets and USB ports.
When you enter the room, the chairs will likely be set up as rectangular table groups of 8 students. In 1D01 and 2D01, the tables accommodate 5 students. The chairs are movable so you can rearrange as suits your delivery and student comfort. The ends of the tables are very comfortable placements for two chairs as well. If you write on the side board, have the students who face away from it move their chairs to the ends of the tables so they maintain good sight lines and still have table space to work on.
If you need a lectern space for your notes, feel free to take up the end of the front middle table. Move any chairs to the opposite end, so you have your space.
If you have two groups of 4 at one table and they will be working on something for a prolonged period of time, it works best if one student moves to each end so that each group feels it has its own space and you can visit each group separately. Also remind students to be conscious of their volume level, as the groups will be in close proximity to one another.
