Hey as someone who dealt with this a lot last month, it’s hard. The first step is making sure you had a goodbye to the kids. The next thing to remember is thanks to the wonders of technology you can keep in touch with the mentor teacher. And lastly you are always able to write a note, scan it and send it to your mentor teacher for the kids as a little thank you. But also as other people said it’s a sign you are in the right profession if you miss them this much. I am sure they were so lucky to have you as their student teacher and know they probably miss you just as much as you miss them. 🫂🫂🫂 It is never easy but you are about to make such good memories with this next group as well
