How to give the classroom a sample answer for an assignment

Hi,

I have created my first assignment using GitHub Classroom and students have submitted their work. Usually while I am grading their answers and giving individual feedback, I would also distribute an example worked answer to the assignment.

Is there a standard way to do this?

I have considered creating a ‘sample answer’ repository in the organisation created for my class. However, although the student repository’s are in the organisation, the students are not in the organisation but are external collaborators on the repositories created for the assignment by classroom. I cannot see how to easily add them as collaborators on the answer repository.

Grateful for any suggestions.

Thanks

William
