In case one of your lovely students ever fails to complete an assignment, have him/her fill out this late work ticket as a reminder to you the assignment is still missing. This also serve as documentation for students and their work habits. In addition, it helps students to recognize their choices and how to create a plan to fix a mistake. Since this sheet requires a signature of both the student and the teacher, communication must also be practiced.
I would consider having a student turn this sheet in as a replacement for his/her missing assignment. Additionally, this sheet could be printed on duplicate or triplicate paper so the student could also keep a copy.
