  1. Timita says:

    I give each student a drawing of a town, with lots of different businesses. I first elicit what each business does (i.e. in the hair salon they cut your hair, at the mechanic they fix your car… etc) to check vocabulary. Then I introduce the grammar and ask what you can have done in each, for example:

    In the hair salon I can have my hair cut, at the mechanic I can have my car fixed. etc.

  2. Houcine says:

    I write the following sentence on the board:

    I have my hair cut every week.

    1. Elicit the form from the students (have/has + noun + past participle)
    2. Use the following concept questions to elicit YES or NO:

    Do I cut my hair? Ss: NO
    Does somebody else cut my hair? Ss: YES
    Do I pay money? Ss: YES

    3. If you cut your hair yourselves, how would you say that? I elicit: I cut my hair.
    4. Elicit that every week expresses “a habit”, and have is in the present simple tense.
    5. Write the following on the board:

    house/clean

    and elicit…

    I have my house cleaned.

    I repeat the concept questions to make sure that students grasp the new structure, and drill it (whole class/individuals).
    6. Written practice.

  3. Poppy says:

    I ask the class who is scared of going to the dentists. Then I tell them all the work I had done when I was young (6 teeth out, a brace for 2 years, now I’m having my wisdom teeth out) and put them in pairs to tell their partners how much dental work they’ve had done (extra vocab too).

    Then you can elicit a few modal sentences from one of the students, put it on the board and clarify the form and meaning.

    In changing it into the active it can be quite funny, as you can’t really take our own wisdom teeth out. You can even bring in some gory pictures! :)

  4. Anonymous says:

    I put on the board pictures showing

    a.) broken down car
    b.) mechanic repairing it.

    Then I say:

    I had a problem with my car and took it to the mechanic and write on the board:

    I had my car fixed.

    Then ask:

    a) Did I fix it? Students answer “No”
    b) Did the mechanic fix it? Students answer “yes”
    c) Did I pay for it? They answer “yes”.

    Finally I write on the board the form of causative.
