What unusual/innovative methods are there to deal with late submissions of assessment? Some context: I was intrigued by a short discussion in another answer relating to dealing with late submissions of work by students, where Jeff suggested giving students a limited number of 12-hour &quot;late tokens&quot; that they can use at their discretion when submitting work late during a course.  The idea of this is to give each student a &quot;budget&quot; for lateness, so that mild sporadic lateness would be okay, but repeated or extreme lateness would break the budget.  This seems like a very clever idea to me.  Hence, the purpose of this question is to solicit information on any other unusual/innovative practices lecturers use to deal with late submissions of assessment in their courses.
Question: What kinds of unusual/innovative methods do lecturers use to deal with late submission of assessment?
In an effort to avoid whining and prolong the lives of grandmothers, I experimented with giving students a bank of &quot;late days&quot; which they could use to defer submission of homework.  In an effort to teach some time management, I made the students responsible for telling me that they intended to use late days before the due date of the assignment.
That did not work.  &quot;I'm sorry my assignment was late, but....&quot; turned into &quot;I'm sorry I didn't tell you I was going to use late days, but...&quot;
