It is hard to remember what students miss while they are absent, here is a form I use that has helped a lot! I will grab on at the beginning of the day and write the names of the students who are absent on top. As the day goes by I will fill in what we are doing that day and set any necessary papers along with it. At the end of the day I will fill in homework as well and pick a responsible date for when everything is due! It is great for making the student accountable for their own work.
