Assessing students understanding of notation

I had a new class and I was trying to work out how much they knew about notation - a powerpoint of the lesson is attached. I used the first page of the Mozart to see if they could identify certain symbols and we discussed what they knew. I had transcribed a section of Ollie Murs Trouble Maker (which was no. 1 at the time) and deleted important parts. I gave this incomplete version to them to work out what was missing and finish it for homework listening on youtube. It helped them realise what to look for in any score (instruments, tempo etc) The complete version is also attached.
