First conditional

Form

If + present simple + will

Functions and examples

We use the first conditional to talk about actions or events in the future which are likely to happen or have a real possibility of happening.

If it rains tomorrow, I will stay at home.
-- I think there is a real possibility of rain tomorrow. In this condition, I will stay at home

If my father doesn't buy me a bike for my birthday, I will be very unhappy.
-- I think there is a real possibility that my father won't buy me a bike. In this condition, I will be unhappy

Important points

We can use other modal verbs in place of will.

If it is sunny tomorrow, I might go to the beach.
-- going to the beach is only a possibility

If you come early, you can see my mother before she leaves.
-- It is possible for you to see my mother

Teaching first conditional

•   1. I usually give some examples of superstitions, e.g. If you break a mirror, you will... (they give the answer, since they already know Future Simple Tense).
  2. Then I give some more oral examples for them to finish.
  3. After that they make their own examples.
  4. Now they write down an example or two.
  5. In groups they try to figure out what goes with the IF clause, what with the main clause. They report back to the class.
  6. In groups, they make new examples of "silly" superstitions.
  For homework, they write several sentences asking other students: What happens if you... (they finish). Other students give answers, and then they choose the silliest one.
  
  I definitely try to make fun of it, because I think the first conditional is easy to comprehend (it is very similar to the first conditional in their mother tongue), so that they aren't bored."

•   1. First I start asking my students what they would like to do. They usually suggest watching a video, learning a new song, playing games, listening to stories, etc.
  2. I write their suggestions on the board.
  3. Then I mention the conditions in order to get what they have suggested.
  4. The sentences written on the board have different colours. I use green for the word "IF", red for the modal verbs "WILL" or "CAN" and blue for the verbs. They immediately notice I am teaching a new structure.
  5. Later I ask them to tell the conditions their parents establish at home, like what will your mother do if you behave well?
  6. In pairs they talk about it.
  7. I help them mention different things their parents have told them about good habits; like what happens if you eat vegetables... brush your teeth... don't smoke... go to bed early, etc."

•   1- After explaining to the students that we use the first conditional to express situations that are likely to happen, I make up a story telling them I am going through a difficult situation, I try to sound very convincing so they'll help me to find a solution for this problem. E.g. I tell the students I've just broken up with my girlfriend, that I suffered very much in the relationship because she was unfaithful to me, I gave her a second chance and she failed me again so I decided not to go on with her and break up. Finally I tell them that she is calling me to beg for forgiveness that she really wants to be with me and she's regretted what she's done. Then I write the first clause of the conditional "if you get back with her,..." the students will try to give me some advice by completing it with the second clause.
  
  If you get back with her, she will make you suffer.
  If you give her another chance, you'll be very unhappy
  
  2- You can have the students create their own situations and share ideas. They come up with very nice or crazy pieces of advice so you laugh very much in class at the same time they are practicing."

•   When I start teaching conditionals I usually ask students what they understand by conditionals? then explain that conditionals talk about a condition which has a result related to it. You can give examples like...
  
  "You want to go to the movies tonight and you have asked your friend to pick you up from home. You are sure that your parents will allow you to go to the movies, but if for some reason they say "no", will you go or not?
  
  "If your parents say no, you won't go."... there is a high possibility of you not going to the movies if your parents say no. Now you can help them to understand that there is a condition (parents do not agree) and the result of that condition (you won't go).
  
  Then, you can give them the structure for when we talk about a condition which has a high possibility:"

•   Ss have pieces of paper... each student writes the first part "If I win the lottery I will buy a car... and then swap papers. So the next student starts the sentence with the last one... Ex. If I buy a car I will drive fast.... and so on.
  Diana Magali
  
•   "If you..., change places!". Students sit in a circle, teacher starts by standing in the centre and says, for example: "If you have long hair, change places!, all students with long hair should get up and change places with another student. Lots of fun!
