Hello! I am a fourth-year Elementary Education major and I have a sister who is also an educator! While she is still able to see her students daily, her educator friends are not so lucky. One thing that they have been focusing is trying to connect with their students through the screen. While this can be tricky, they have been creating small activities that let the students see if they anything in common with their peers or with the teacher. The activities range from show and tells to allowing the students show their families and pets off at the beginning of the school day.
I am so glad that you asked this question as I am going to be student teaching next semester. It is nice to know what other teachers are doing so that you can try and incorporate it yourself!
Hope you find the advice that you are looking for!
