If I’m teaching a drone class, can only one student fly at a time?

Hello,Thanks for any advice.I’m teaching a video production class at a high school career center. The principle wants me to include some drone lessons.I know that when I have the part 107 a student can fly under my supervision. Can only one student fly at a time? That seems to make sense I just want to double check.Thank you! via /r/drones https://ift.tt/2XxZ3Tv
