Thankfully, there is a variety of business English textbooks available that practice presentation skills, describing charts, formal communication, etc.
In my experience, I have found the Intelligent Business series the best for business English.
For these reasons, I usually bring a few textbooks to the first meeting.
This shows that I am serious and have resources available to help the student.
If the student is a housewife who is interested in more general topics, I might bring an ESL lesson plan on the family.
In the last 5 minutes of class, I review the student’s mistakes.This is a good opportunity to see if the student can form proper questions. If the student does not ask any questions, I will give them a short outline of my teaching experience and qualifications.I expect questions like “How long have you been teaching? Next is the most important thing: identifying the needs of the student(s). I may ask if the student has taken or plans to take any language tests.(If you don’t have any textbooks, don’t worry — most things can be found online if you are resourceful or you can have the student purchase a textbook afterwards if need be).It is also helpful to develop a class cancellation policy at this point as well.
