Hello, Whilst I'm not James I had the exact same question on my second placement. I was attached to my mentors tutor group and there appeared to be a divide down the middle of the room. They also really liked my mentor and I was met with resistance for a while was they thought I was the devil! Anyway, devil aside, the best activity I found was redesigning the tutor board. We all made handprints and stuck them around the side. I also gave each one a small sheet which had questions like what is your favourite food, what do you do outside school etc... but the catch was they had to find someone else to fill it out about and it worked well. I hope this helps I'll try and find a copy of that sheet I used and upload it.
