With the initial use of pacing tools, students may not finish in the allotted time. This may indicate that the teacher needs to provide more time guidance or instruction.
Try having a time keeper or student who manages the clock so the teacher does not have to.
Put the clock in a place where everyone can see it, and so that students can self monitor.
Keep in mind individual student needs in regards to allowing extended time for assignments.
Work the Clock is a practice that emphasizes the importance of class time by announcing an allotted time for an activity and mixing in countdowns to remind students of work-time remaining and encourage on-task and efficient work for long or short durations for the lesson.
Songs can be used in lower grades since students may not know how to read a clock or understand time. The teacher can lower the volume so that students know when the song is about to end and they should finish their work.
