Students fill this form out when they do not have their homework. This form requires the student to give a reason why they are missing the assignment. This helps me identify if there is an underlying problem as well as serving as a record of their missing homework. This is especially handy when a student or parent claims the assignment was turned in on time. Since the form is also signed and dated by the student, it leaves little room for questioning.
I copy this on red paper so that it is easy for me to see in the stack of homework papers.
