STEP 2: Read
INDEPENDENT WORK: Let's Do It! No. I

What does Jenny use the Internet for
What device does Jenny use How is it different from a computer

What will Danny do if they have a meeting What does Brian use the Internet for
What device does he use
What will happen if Brian works hard this evening
What does he want to do tomorrow
Who does Brian want to send his research and why
2) Explain the use of the adverbial clause with "if”.
A complex sentence is made up of an independent clause and a dependent clause. For example: She will miss the bus(independent clause which can stand alone and make sense) if she doesn't hurry (dependent clause which must be attached to the independent clause to make sense). There are three kinds of dependent clauses: adjective clause,adverb clause and noun clause.
An adverb clause is a dependent clause that modifies a verb, adjective, or another adverb. It usually modifies the verb.
Adverb clauses are introduced by subordinate conjunctions including after although, as, as if, before, because, if, since, so that, though, unless, until, when, where, and while.These are just some of the common ones.
For example: They won't go the game if it's raining. ("if it's raining" is the adverb clause modifying the verb "go" telling what)
Sometimes the adverb clause is placed at the beginning of the sentence. When it introduces the sentence, it is always set off with a comma. For example: If it's raining, they won't go to the game.
STEP 4: Role-Play
GROUP WORK: Role-play the lesson
1)Instruct the students to role-play the lesson in groups of three.

CLASS CLOSING

The Internet and Me: Choose three things you use the Internet for and write a short passage about it. Also mention, what device you use most often and why (i.e. tablet, smart phone, laptop computer. desktop computer). Be sure to use the adverbial clause with "if' at least three times in your passage.
EXTENSION
GROUP WORK: Web Search Activity
1) Divide the class into groups to complete this task. Students will need Internet access for this task. 2) Provide each group with a list of general things to search and find on the web. Ask them to record the results of their searches (websites and information) and the keywords they used in table (see the example below). Students should take notes of which searches were successful and which were not. Successful searches should yield accurate and relevant results. Before they begin their search, however, they ought to consider what information about each topic is most important. This will help them decide what keywords to search.
For example: You may ask the students to find websites or information on the following topics.
Knitting a scarf
(For this topic students should search what you need
to knit a scarf and how to knit scarf.
They may even look for images, step-by-step
instructions, videos, etc.)
