Help yourself and your students manage missing and late work. If a student does not have an assignment to hand in, he or she instead fills out the Missing Assignment Form. One half gets turned in where work usually goes, while the other half stays with the student.
Use it in a way that works with your classroom management style! These have helped me so much; I just wanted to pass them along.
The one-page PDF contains two half-sheet tickets (that then get cut in half by the student). Smaller, quarter-sheet version is forthcoming!
