Teaching causative
I ask students to imagine they were rich and could have all sorts of things
done for them, annoying everyday chores that nobody likes doing plus some luxury
pampering that money allows for.
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 - in the hair salon I can
have my hair cut, at the mechanic I can have my car fixed, etc."
I write the following sentence on the board: I have my hair cut every week.
In a previous class I ask my students to tell me about the services they need
and the establishments that are near their homes or the ones they usually go to.
According to the information they give, I elicit the services and I write on the board some examples like
Family - friends and favours.
Question:
Al - this is causative in the present perfect. I'd suggest teaching it in conjunction
with "Have you ever..." type questions."
I usually ask my students to think about the things they don't like or don't know how to do by
themselves. Then I ask them how they manage to get them done, I repeat some of the first answers with
the causative form. Then the rest of the students are asked to model according to the new type
of sentences I have introduced."© eslbase 2005-2009 - TEFL jobs and TEFL courses, information, advice and ESL resources for teachers - English grammar: Causative
