Step 1 Revision

2 Revise be going to by asking Ss about their plans for this evening, next Sunday, etc.
3 Ask individual Ss to open the door, close the window and do other classroom duties. As they stand up to obey, ask What're you going to do? Then ask the class What's he/she going to do?
Step 2 Presentation
Show a flashcard of some oranges(or bring in the real thing).
Say I'm going to the shops today. I'm going to buy some oranges.
Repeat. Ss listen and repeat.
Explain that I'm going to the shops is a quick way of saying I'm going to go to the shops.
Show flashcards of other food(e. g. rice) and get the Ss to say I'm going to the shops today. I'm going to buy some rice.
Step 3 Practice
Get the Ss to make a shopping list of four items for supper. Ask individual Ss What are you going to buy? Then Ss can ask and answer in pairs.
Step 4 Read and act
SB page 14, Part 1. Read through the questions in Wb Lesson 14, Ex. 1, and then let the Ss read the dialogue silently to find the answers. Explain that get =buy and Why not? is another way of saying Good idea! Note that a few means some, not many. Speech Cassette Lesson 14. Play the tape, then practise the dialogue with the Ss.
Divide the class into two groups to practise similar dialogues using pens and pears. Then Ss work in pairs. Ask some pairs to act out their dialogues. See who can do it without books!
Step 5 Presentation
Revise the comparative and superlative forms, using small pieces of paper：
This piece of paper is small. This is smaller. This is the smallest of all.
Draw three sets of oranges on the Bb, with a different(cheap) price on each.
Point to the highest price and say These oranges are cheap. These are cheaper. These are the cheapest of all. Make sure the Ss understand cheap.
Repeat. Ss listen and repeat.
Make the prices higher, and practise with dear in the same way.
Now point to the oranges, starting with the cheapest, and say These oranges are good. These are better. These are the best of all.
Practise the sentences by saying an adjective(e. g. good) and getting the Ss to point to each set of oranges as they say the appropriate sentence.
Step 6 Practise
SB page 14, Part 2. Read through the sentences with the Ss. Ask Which pen/oranges/cake are they going to buy? HELP THE Ss to guess, using I think they are going to buy the cheapest one(s)/ the best one.
