Hello, I had an interview and an offer last week for Cumbria university and we had to bring the same thing. They're not too bothered about what it is that you bring, its more about how you can show your knowledge of the curriculum and if you present it with confidence. I brought in a teddy and related it to speaking and listening. Someone brought in buttons and talked about numeracy activities. A few brought in flashcards related to phonics. One girl brought in a puppet.
You're also scored on how many questions you ask about other peoples objects and how active you are in discussions.
Good luck!
