Build student knowledge about an array of careers by creating a "Who Am I?" career challenge. To prepare this activity, select 10 different careers. Think about what are the job duties of each career, and write a riddle for each. Make your riddle vague enough as to not be overly obvious, but specific enough so that students can successfully deduce the answer. For example, you could write: “In my job, I work with lots of children. Sometimes we play games, but most of the time we work hard. I work hard, and I enjoy what I do.” The answer is, of course, a teacher. Read the riddles to the students one at a time. Allow the students to raise their hands if they have a guess. Reward the students who guess correctly with a piece of candy or other small token.
