Teacher can make this activity a game. Go through the groups’ sentences and give marks to the groups with all correct sentences.

Conditional sentences type 2

Write this incomplete sentence on the board:

If I were a billionaire, I would ... . Ask some Ss to complete the sentence orally. Write the most original answer on the board. Tell Ss that this sentence is an example of the conditional sentence type 2.

Have Ss look at the structure as the conditional sentence type 2 in the language box. Draw Ss’ attention to the example sentence on the board. Underline the subject, verb, etc. in this example and explain the structure of the sentence at the same time.

Ask one or two Ss to write their sentences on the board.

Further practice (5’)

CHAIN GAME

Work in groups. Student A begins with a conditional sentence type 1 or type 2. Student B uses the end of student A’s sentence to begin his/ her own sentence. Student C does the same. Continue the game until the teacher tells you to stop.

Which group has the most sentences?

Put Ss in groups of five or six to play this chain game. Explain that the aim of the game is to keep the chain going for as long as possible using type 1 or 2 conditional sentences. If a group hesitates for more than 10 seconds they are out. Walk around the class listening to groups and monitoring the game. Groups that are still going when the five minutes is up are the winners. Note that the aim is to practice the language in a fun, verbal way so be sure to keep the atmosphere light.
