Procedure (30-45 minutes)
T tells ss: I have a video for you to watch. T plays video: Mr. Bean in the Cinema to set context for obligation. T elicits from students: Where was Mr. Bean? ( in the cinema) . What was he trying to do? (smoke, drink, talk on his mobile).. Was it against the rules for him do these things? (Yes ) What do the rules let him do? (buy drinks and popcorn ) T asks ss to discuss in small groups: What are some other rules you would expect to find in the cinema? T nominates a few ss to share answers from their group.
-ask SS to read a passage about " Mobile phone etiquette" and pay attention to the highlighted phrases. Then ask them questions about the passage. What was it about? about mobile phone etiquette. Do you agree with what he said? yes ask them to match the highlighted phrases to their meanings.monitor SS to check their answers in pairs and check if they have difficult in understanding. -feedback
Write the phrases on the board and elicit their rules . you should change it. you must not use your phone. you don't have to shout. you have to keep your phone on. you must take a call. Then clarify their meaning and distinct them from each other. should (weak)= used to show what is right, appropriate, etc., especially when criticizing somebody’s actions must (strong) = We use “must” to talk about obligations. Often, when we use “must”, the authority for the obligation comes from the person who is speaking have to (rules) = We can also use “have to” to talk about rules and regulations. The authority for the obligation doesn’t come from the person who is speaking. Perhaps the rule is a general law or obligation. Positive: Subject + Should/must/ have to + V + Object. Negative: 1. Subject + Should/must + not + V + Object. 2. Subject + don’t/does not+ have to + V + Object Question: 1. Should/must+ Subject + V + Object? 2. Do/Does + Subject+ have to + Object call them to the board and give them one word to go to their rigth place as a part of a sentence and play a game to understand the rules better. S1= clean S2 = your S3= room S4= should S5= You positive sentence: 5 4 1 2 3 negative sentence : 5 4 Not 1 2 3 ( me play as NOT) question: 4 5 1 2 3 ? ( me play as ?)
