Point to each one and teach them to read. Do it several times until the children can read them well.
Ask a few students to read the new words. See if they can read each word correctly.
Ask the students to read the instructions together.
Write the names of the inventions on the blackboard:
Shoes with adjustable heels
battery operated slippers
heated ice cream scoop
Read the three names of the inventions and the students repeat. Do some explanation as well.
Then point to the picture of each invention and ask students what they think is interesting about it.
You'll hear about some interesting invention . Please listen and number the three inventions in the order that you hear them in the conversation. Write a number in front of each invention to show what order you hear about them.
Play the recording the first time, students only listen. Then play the recording again. Ask the students to write a number on each short line in front of each invention.
Check the answers by asking a student to tell the answers.
Answers
The inventions should be numbered in this order:
3 1 2
Tapescript
Boy: What are those?
Girl: They're battery-operated slippers.
Boy: What are they used for?
Girl: They're used for seeing in the dark.
Boy: Oh, that's cool! Who were they invented by?
Girl: Julie Thompson. And look at this heated ice cream scoop.
Boy: I know what it's for! It's used for scooping out really cold ice cream.
Girl: Right. It was invented by Chelsea Lanmon.
Boy: My favorite are those shoes with adjustable heels. You know—you can move the heels up and down. They were invented by Jayce Coziar and Jamie Ellsworth.
Girl: And what are they used for?
Boy: Well, you can change the style of your shoes. You can make the shoes go from casual to dressy.
Step Ⅲ 2b
This activity provides guided listening practice using the target language.
Get the students to read the instructions together. Be sure that each student knows what to do. Read the three headings Inventions, who was it invented by? and what is it used for?
Then read the information under each heading. Do some explanation if necessary.
You'll hear the same recording again.
Please listen carefully to what the people are saying and draw lines to match items in the chart.
Call the students' attention to the three part sample given in the chart. Read it to the class and explain it like this:
The sample means the shoes with adjustable heels were invented by Jayce Coziar and Jimie Ellsworth. They are used for changing the style of a shoe.
After that, play the recording again and the students draw lines to match the items in the three columns.
Check the answers by asking three different students to read their answers to the class.
At last, play the recording for another time and pause after each sentence. The students repeat after it sentence by sentence. Do some explanation if necessary. Make sure that everyone understands all the details about the conversation.
Answers
shoes with adjustable heels—Jayce Coziar and Jamie Ellsworth—changing the style of a shoe
battery—-operated slippers—Julie
Thompson—seeing in the dark
heated ice cream scoop—Chelsea Lanmon—scooping really cold ice cream.
Step Ⅳ 2c
This activity provides guided oral practice using the target language.
Read the instructions to the students.
Ask a pair of the students to read the sample conversation.
SA : What are they used for?
SB: They're used for seeing in the dark.
Get the students to ask about the three inventions first, using the information in the chart in Activity 2b.
Then let them role play the conversations using the information in the chart in Activity 2c.
Get them to make their own conversations using the information in the chart in Activity 2c like this:
(Pointing to the inventions)
A: What are these?
B: They are battery-operated slippers.
A: What are they used for?
B: They are used for seeing in the dark.
A: Who were they invented by?
B: They were invented by Julie Thompson.
Ask the students to work in pairs. Move around the classroom checking progress and providing help if needed.
Check the answers by calling on different pairs to say their conversations for the class.
Step Ⅴ Grammar Focus
This activity introduces the target language with the Passive Voice.
Call the students' attention to the sentences in the grammar box.
Ask four pairs of the students to read the questions and answers in the grammar box.
SA: When was the car invented ?
SB: It was invented in 1885.
SA: When were electric slippers invented?
SB: They were invented last year.
SA : Who were they invented by?
SB: They were invented by Julie Thompson.
SA: What were they used for?
SB: They were used for seeing in the dark.
Write them on the blackboard.
Let the student think about the structures of these sentences.
Tell them that when the subject of the sentence is the doer, we have to use be plus a past participle' as the predicate of the sentence.
Circle the words was and were in all the sentences.
Ask: When do we use was in the questions, and were in the questions?
Underline the singular nouns and plural nouns.
Singular items like car use the singular verb was. Plural items like slippers use the plural verb were.
Circle the word invented in all the sentences.
You always use a past participle when you use was plus a verb or were plus a verb. And you can tell the doer with by. Say something about be used for to the children.
