Many ESL students have difficulty polishing their telephone skills. Even advanced ESL students have a hard time concentrating on their business English skills on the telephone. One way to practice concentrating during telephone business conversations is to have two students make a mock business call to each other while the rest of the class tries to distract them. The two students should sit back to back, facing away from one another, and should speak loudly enough to be heard. The rest of the class should be divided into two groups, with each group trying to distract one student. The student who incorporates the most sentences or business vocabulary into the conversation wins.
