1) ask everyone "Who Are You?", encourage them to answer differently (e.g. I am Nick/American/a boy/teenager etc.), then ask to think and explain why the thing they said was the first thing to mention. This should be smth really important in their life if they said it first! (what is important for your students? name? religion? nationality? - make them explain).
2) cut the stripes of the answers to "Who Am I?" question and make two groups discuss and put the items in the order of importance. Then each group explains why being this or that is an important or not such an important part of their lives.
