When students are in the queue, if they don’t use thier pass immediately, they get the message “0s left to start your pass or it will be sent back in line.” If the teacher needs to stop students from leaving for a period of time, the line should just stay as it is, rather then cycle through the kids in line. Also, this encourages students to immediately take a break when the student returns where they might have been engaged in a task and not wanted to take a break.
