To introduce the language should, must, have to, need to along with their sometimes confusing negative forms. I gave my students the printout of this casting call for extras for Pirates of the Caribbean 3. After we established what a casting call is, they individually read through for comprehension, asking questions along the way. They had a good time with the colorful Hollywood way of describing pirates and wenches.
After they understood it on a sentence level, we then talked about the purpose of the announcement, establishing who was likely to respond to the announcement, what kind of advice they would need, and why the studio would want to give them such advice (to keep from wasting time with a zillion extras).
On the board I had written in three separate columns “Encouraged/Required,” “Not Required,” and “Discouraged/Prohibited.” I had them call out points from the announcement that fell into each category. This way they were able to figure out for themselves the distinction of this middle area of “Not Required” vs the other two. And, as we filled in the categories, some of the phrases they offered were inevitably lifted from the text and included our key modals: must, should, must not, should not, need to, have to, do not have to, do not need to.
I then highlighted that each of these fell into each category with consistency. That these auxiliary verbs commonly indicate advice. I then had them extract positive advice sentences: must, have to, need to, should, and then order them based on strength of suggestion. Then did the same with negative: must not, should not. And again with neutral: do not have to, do not need to.
I then had them structure sentences using these modals with other pieces of advice, first given in the announcement and then things they might suggest as a casting director or agent.
PDF of the casting call site– I edited it for brevity, taking out a few of the points that didn’t illustrate the lesson and substituting the word “must” in one or two instances in order to provide an example of its usage:
