I've have started doing this Kate - thanks for suggesting it. That short phrase/sentence means that we both know that this is the last thing. I experimented with your idea and I am leaving it until slightly later in the lesson and giving a clear - 'let's play through this to finish' kind of thing (but with your 2/3 or 3/4 idea in my mind, so the times work).
I have also moved my clock so its easily visible to all from the music stand. Thanks for your help
