What teachers need to do if assigned a task and some of the students have already completed it but others are still working?

Teachers should assess the situation by identifying which students have completed the task and which are still working. They can provide support and encouragement to those who need more time, ensuring that they understand the material. Additionally, teachers might consider differentiating instruction by offering extension activities for those who have finished, while allowing others to continue working at their own pace. Communication and flexibility are key to addressing the varying progress levels among students.
