Cora Chen created this online exercise in January 2005 for ESL 7-9 (non-credit) or students who are taking credit classes.

Its activities allow for different grouping strategies--individual, pair or group work. Reading, writing, and speaking skills are integrated in this exercise (students can practice speaking through pair or group discussions.) These activities also promote critical thinking.
