At the beginning of class I do a quick survey with the students. With their eyes closed and heads down, I ask and write down how many students raise their hands when I ask "I think ___ is cool." I used math, science, snowboarding, soccer, baseball, Big Bang, Girls Generation, Beast, Exo, Miss A, Shinee, Naruto and Pororo but add your own.
While they do the word search, I edit the Powerpoint (remove slides and add percentages) to reveal the survey results at the end of class.
