Should i ask for their make up work?

Hi! I'm a parent here asking this question. I have a son who is in Elementary school and my Nephew who I am taking care of is in middle school. (Their school has all k- 12 grades so they go to the Same one)

We left for Disney early this week, school in my area was closed every day except for 1.5 days because of inclement weather at home. We are also going to be gone all of next week.

Is it okay to email teachers Monday morning and ask can they email me the work the kids missed? Or should I wait till they get back and make sure they get everything? Also is it a big hassle for teachers to give things to students who missed time? If so I'm thinking about bringing back a small gift for both teachers. Thanks!
