My experience is coming from an elementary school perspective; I would have a buddy to assist with any tasks like gluing materials in journals or writing notes in journals. Then I would pull the student in a small group with students who may need a review on what topics you’ve taught. There’s a chance that at least one or two other students will need whatever you taught again. Also, there were times that I would send home some of the work with videos to watch or a help sheet with examples. I would communicate with parents ahead of time to be sure that they could work with the student at home. Sometimes this isn’t possible so I would resort to the aforementioned ways to meet the absent student’s needs.

Our school utilizes our Title 1 and 31A teaching team, foster grandparents, and parent volunteers to help students get caught up. In the classroom they use folders (with missing work inside) labeled "Catchup Time" (bottle of Ketchup is included).

I only caught them up on key concepts. Not all of the work. Because in primary, there is embedded in lessons, a lot of repetition.

If at all possible, create the procedure for parents and guardians letting you know if their child will be absent from school multiple days. Once the procedure is established, I can communicate with families about ways they can keep their student engaged and caught up while they are away.
From the elementary perspective, we do not require missed work to be completed and returned, however I will pull the student to work on any essential skills he/ she may have missed.
I think the communication piece is the most essential in keeping kids engaged if they are not in school.

In kindergarten, it is often very difficult for me to send home any missed work because we do most everything in a hands-on way. When families ask for things for their students to do if they have been out sick or will be out sick, I will gather work pages that relate to the concept we are learning about and I will send those home with the child.

If the child is absent for a few days, I will collect some items and place them in their student mailbox and when they return to school, they are able to pick them up, take them home and have a week after returning to complete them.

I only catch up on key assignments. Many key concepts are repeated, or I will embed a review in an upcoming lesson.
