My colleagues and I team teach so our students are regrouped for every class. Each student has at least one other person with whom they have the same schedule. Whenever a student is absent, another takes a Work Record Sheet, a listing of all the classes by the day of week, and fills it out with what was collected, discussed and assigned in every class for their partner. The 'homework buddy' receives a slip for entrance into the monthly school wide Reward Lottery. If parents call to get work for their children, it's all ready to go and the children know that they were missed when they were gone.
