Teaching Procedures	Tips
Step 1 Warming up
Play the song whatever will be will be to Ss, ask them to listen to the song and fill in the blanks. T can ask Ss to pay attention to the simple future tense (the usage of “will”.) Revision Ask each S to find a partner. T shows them the pictures on PPT P6 and P7, ask them to make a prediction about each picture with their partner. T can ask Ss to make more predictions, e.g. Will there be more or less pollution? Why? Free Talk Work in pairs, ask Ss to talk about what they can do to protect the environment. Remind Ss that everyone should save the planet and protect the earth.
Step 2 Presentation & Practice
While-listening 2a Ask Ss to listen and circle the words they hear. T may want to preview as a class the possible responses in activity 2a before Ss listen to the recording. In this way, Ss will consider the grammatically correct options. The T should have Ss predict which of the responses they will hear in the recording. After Ss have listened to the recording, T can elicit which of the S(s) predicted the greatest number of responses correctly. Answers: circled: 1.more 2.less 3.fewer 4.less 5.fewer Explain “there be” structure in simple future tense and the usage of “more”, “less”, “fewer” to Ss. 2b Play the recording again. Ask Ss to check the predictions they hear. T may want to have Ss close their textbooks and write down the predictions they hear. Then have Ss open their textbooks and use their notes to answer the questions. Answers: Checked: 2, 5 Show PPT P14 to Ss. Ask them to listen again and write T or F for each statement. Answers: T, F, T, F Post-listening 2c Pair up, ask Ss to make conversations about the predictions in 2a and 2b. T can ask Ss to make more predictions about future using the pictures on PPT P16. Optional choice: T can use a game to help Ss practice the conversation. Step 1: T selects one S to stand at the front of the class but with his or her back to the other Ss. Step 2: T reads a prediction (from 1a, 2a and 2b or an original prediction). The S at the front writes down whether he or she agrees or disagrees with the prediction. Step 3: The other Ss move to one of the sides of the room. Ss who predict the S is going to agree with the prediction stand on the left. Ss who predict the S is going to disagree with the prediction stand on the right. Step 4: T should ask the S at the front to reveal his or her answer. Ss who did not correctly predict the answer sit down. Step 5: The Ss standing can continue in the game. Step 6: T should repeat the process until there is only one S left standing or until all predictions have been considered. Tips: T can encourage the S who stands at the front of the class to give opinions on why he/she agree or disagree with that prediction.
Step 3 Presentation & Reading
2d Ask Ss to role-play the conversation with their partner. T may want to have Ss change the conversation after they have practiced the original conversation. Step 1: Write on the board: A: So what will the future be like? B: ... A: What will happen? B: ... A: What can we do? B: ... Step 2: Elicit from Ss some possible answers for speaker B and write the answers on the board. The answers should include a mix of positive and negative ideas. Step 3: Have Ss practice the conversation in activity 2d, adapting it to utilize the ideas on the board. Let Ss to read the conversation again, ask them to find out the answers for the following questions: What is Jill reading? What will the future be like according to the book? What can people do to save the earth? Show PPT P21 to Ss. Ask them to close their books and fill in the blanks according to the conversation. Answers: will, be, will be, will be, will be, Will, have to, less, more, play a part in
