Step Ⅲ Part 2
This activity provides reading and writing practice using the target language.
First, teach the names of the five inventions with books closed like this:
Show a real abacus to the class and say, We call this an abacus in English.
Write the word abacus on the blackboard. Then point to it and teach the students to read it.
Do the same with the other four inventions—umbrella, binoculars, camera and bicycle.
As a bicycle is too big, show a picture of it instead of a real object. Then ask the students to open their books.
Read the instructions to the students. Be sure that the students know what to do. Have the students look at the sample. Ask a good student to read the sentence to the class. Correct any pronunciation errors to make sure the student are providing a good model for the rest of the class.
Provide the information of the other four inventions on the blackboard: (Or ask the students to find out the information by reading an encyclopedia or looking up information on the internet as homework.)
umbrella: about 4 000 years ago in Assyria, China and Egypt.
binoculars: 1854 Ignatio Porro in Italy
camera: 1827 by Joseph Nicephore who took the first picture
bicycle: 1880s in England.
Let the students write paragraphs about these things on their own.
Move around the classroom and provide help as necessary.
Ask several children to read their paragraphs to the class. Correct the answers with the rest of the students.
Have the students exchange their paragraphs with their partners.
Get them to look over the articles carefully, correcting any mistakes they may have made in writing.
