I am very new to this so I am sorry if this is an obvious question. 

Is it possible for a teacher to mark a paper copy of a writing task, give it a mark ( submissions/paper), then snap a photograph of it and upload it? I can see the children can respond to assignments and add things yet can we as a teacher on our logon do it? 

Or..where/ how can we ( as the teacher) add samples of their work that align with the results?
