Questions:
1.Which one do you think is the oldest?
2.Which one is the newest?
3.Which one do you think is the oldest or the first invention?
4.Which one is the newest or last invention?
Ask different students to answer the questions.
Have the students look at the example conversation in the box. Ask two students to read this conversation to the class.
A: I think the telephone was invented before the car.
B. Well, I think the telephone was invented after the car.
Read the instructions again to the students. Remind them to remember the inventions from first to last.
Then have the students talk about the five inventions in groups of four, using the sample conversation as a model.
Ask several groups to tell the class their answers. The rest of the class listen to them and show they have different answers by raising their hands.
In the next activity you will find out the real dates.
Step Ⅲ 1b
This activity gives students practice in understanding the target language in spoken conversation.
Get the whole class to read the instruction together.
Call the students' attention to the five inventions in the picture. Ask five students to say the names of them.
Then ask them to see the five dates with a blank line in front of each.
We'll listen to a girl and a woman talking about the five inventions. They will talk about when they were invented. Listen carefully and match the inventions and the dates. Write the correct letter in front of each date as the sample given. Ask them to have a look at the sample answer. Tell them the answer in front of 1876 is d. That means that the telephone, which is letter d, was invented in 1876. Play the recording the first time. The students only listen and try to catch the main idea.
Play the recording a second time. Let the students match the inventions and the dates. Check the answers by asking several to say the answers to the class.
If some of the answers are hard to get for the children, tell them not to worry and they will make it next.
Then play the recording again. Pause after each sentence and let the students repeat. For some difficult sentences, get the students to repeat several times. Be sure that they make everything clear.

Step Ⅳ 1c
This activity provides guided oral practice using the target language.
Read the instructions and point to the list of dates in Activity 1b.
You will be talking about the dates things were invented with a partner.
Call the students' attention to the example in the box. Ask a pair of the students to read this conversation to the class.
SA: When was the telephone invented?
SB: I think it was invented in 1876.
Write the conversation on the blackboard. Then get the students to practice in pairs, using the information in Activity 1b. Tell them to do it like this:
Student A, covers the dates. Students B, asks Student A when the things in the picture above were invented. Then change roles and practice again.
Ask several pairs to share their conversations with the class.
