Starter or Plenary for Hot Deserts

Here is an easy starter or plenary for hot deserts (which you can also do with any topic). I come up with 3 sets of questions and colour-code them according to how difficult they are. I then fold them, put them in a container and students take turns to pick one out; they can decide whether to go for something easy or a bit more challenging. 
They can either answer it themselves or they can nominate a friend (to save any embarrassment of not being able to answer).


I also sometimes do it in teams with different points awarded for each colour/level, and a wrong answer means all the points go to the other team, so the harder the question the more risky it is.

Let me know if you have any other easy, flexible, differentiated starters and plenaries!
