    Find out how the writer combined the phrases in the notes into one sentence and try to say out the next sentence.
    Let them think for a while. Then ask several ones to say their sentences to the class. The sentences will vary, but have to be correct and meaningful.
    For example, someone may say like this:
    The original flying disk was really a metal pie plate from a bakery in Bridgeport, Connecticut.
    Then ask the children to make their own sentences with the notes given and note to say out the sentences in proper order to be an article. Let them work in pairs, listen to and help each other.
    After that, get the students to write their own articles. More around the classroom while they are writing, checking progress and offering help as necessary.
    Next, ask several students to share their articles with the class.
    Correct the mistakes they may have made.
    If time permits, get the students to work in pairs and check each other's article.
    Sample writing:
    The flying disk is a toy which was invented by a group of college students. It was invented in the 1950s.
    In fact, the students didn't invent it. They just discovered it. The original flying disk was really a metal pie plate from a bakery named Bridgeport in Connecticut. The students there liked to eat the bakery's pies. And then they threw the pie plates around. A company began making plastic disk. Now there are flying disk clubs, a flying disk magazine, and even a national flying disk festival in September. Don't you think it's amazing that all this started from a pie plate?
    Step Ⅳ 4a
    This activity provides reading and writing practice using the target language.
    Read the instructions to the students.
    There is always something that we hate doing. For example, I hate cleaning the blackboard. What about you?
    Then ask some children to say the things they don't like doing to the class.
    After that, continue saying. Now please think of an invention that could help you. For me, I want to invent a self-cleaning board with something like a car's windsheld wipers. Then I would never need to clean the blackboard myself. What about you?
    Get the students to discuss the things they hate doing and the inventions that could help them. Let them work in pairs. Then call the children's attention to the chart on the right.
    Get them to look at the sample answer and try to complete the chart first.
    Ask some children to give their answers to the blanks of use and price. Such as, Use: to write tests instead of me by listening to me
    Price: one hundred yuan per pen
    Then get the students to fill in the chart with the details of their own inventions. Don't review the task. It will be done in the next task.
    Step Ⅴ 4b
    This activity provides listening and speaking practice using the target language.
    Read the instructions to the class.
    Get the students to ask and answer questions about their inventions in pairs first. Ask a pair to make a model conversation before the whole begin practicing. For example, they may say like,
    (B—Businessperson, I—Inventor)
    B: Excuse me, what invention was invented by you?
    I: A special pen.
    B: What is it used for?
    I: It is used for writing tests. While the test is on, the pen can write tests instead of persons according to what its owner tells it.
    B: Wow. that's great. How much would you like to sell it for?
    I: I hope I can get 100 yuan.
    B: OK. I will try to sell it to the class. After that, let the students work in pairs. Imagine one is a businessperson and the other is an inventor while they are practicing.
    Ask several pairs to share their conversations with the class.
    Then tell them to look at the model conversation in the box.
    Ask one student to read the conversation below to the class:
    A: This special pen was invented by Zheng Jie. It has three colours and it is used for writing tests. It can listen and write while the test is on. It is 100 yuan. Is anyone interested in it?
    Then ask some others to share their presentations with the class.
    They have to state the reason for buying them.
    Then the class votes for the most popular invention they want to buy.
