For students at the higher end of the grade range for this exercise, it may be helpful to connect this lesson not only to intercultural competence, to definitions of leadership. In that regard, I am fond of the leadership rubric developed for a charter school in Illinois, which talks about the need to be able to "sharpen one's own saw."  It can be found here: https://uei.uchicago.edu/learn/Leadership_Rubric_CGW.pdf
