Trouble whilst editing

Last week I filmed some of my classroom scene, in which I have a shot of; the class going into the classroom from the outside, the teacher telling the class to take their seats, a shot of the class sitting down, a shot of the teacher giving the class instructions, a shot of the class getting on with their work and the main character putting her hand up to ask a question.

When one of my extras who is in the class walks into the room, she comes in without a book. I took two shots were the main character puts her hand up to ask a question; one where the class are just looking at their books and she puts her hand up, and one where the class are flicking through their books whilst she puts her hand up. The shot where they are flicking through their books is the better shot, however in that shot she has a book.

I'm unsure on whether I want to re-film the shot altogether, or whether I could shoot the teacher telling the class to take out their books, followed by the shot of him giving the class instructions and then the shot of the class flicking through their books and the main character puts her hand up. I don't want to lose the last shot because I think it's definitely the better shot, so I'm swaying more towards just filming a shot where the teacher asks the class to get books out. In the first shot one of the extras is blocking the main character so you can't really see her, but in the second shot you can see her properly.
