This form can be used when students miss school to include quick notes from the teacher regarding work they need to make up.
I use this in my classroom throughout the entire year and students know if they are absent, they can expect this on their desk the morning they return with the attached work and copies of notes if applicable. I begin the sheet the morning they are absent and add the work throughout the day as the rest of the class receives work so I don't miss anything or forget. This also stresses the importance of student responsibility to return the work and allows them a snapshot of what happened while they were gone.
Also, it prevents students from immediately bombarding you with, "what did I miss!?" questions the second they walk in the door! :)
