🔤Future Possibilities: Mastering the First Conditional

This lesson introduces B1 adult learners to the first conditional, a key grammatical structure for discussing real future possibilities and their consequences. Students will learn to form and use first conditional sentences accurately in various contexts, from daily planning to making predictions.

Lesson plan

Objectives

  • Students will be able to identify the form and function of the first conditional.
  • Students will be able to construct grammatically correct first conditional sentences to talk about future possibilities.
  • Students will be able to use first conditional sentences to express plans, make predictions, and discuss potential outcomes in speaking and writing.
  • Students will be able to differentiate between situations requiring the first conditional and other conditional forms (e.g., zero conditional).

Materials

  • Whiteboard or digital equivalent (Jamboard, shared document)
  • Markers or digital pen
  • Handouts of reading passage and grammar exercises (if offline)
  • Internet access for online resources/shared screen
  • Picture prompts (e.g., images of different weather, activities, problems)
  • Timer

Warm-up

Begin by asking students: 'What are your plans for the weekend?' After a few responses, ask: 'What will you do IF it rains on Saturday?' or 'What will you do IF you finish your work early?' Write a couple of their responses on the board, highlighting the 'if... will...' structure. Explain that today's lesson will focus on talking about future possibilities and their likely results.

Presentation

Explain that the first conditional is used to talk about real and possible situations in the future and their likely results. **Form:** If + Subject + present simple, Subject + will + base form of verb. Example: *If it rains, I will stay home.* The 'if' clause can also come after the main clause. In this case, we don't use a comma. Example: *I will stay home if it rains.* We can also use other modal verbs like 'can', 'may', 'might', 'should', or 'must' in the main clause instead of 'will' to express different degrees of certainty or advice. Example: *If you study hard, you might pass the exam.* Example: *If you feel sick, you should see a doctor.* **Use:** 1. **To talk about future possibilities and their results:** * *If I save enough money, I will buy a new car.* 2. **To make predictions:** * *If the weather is good tomorrow, we will go to the beach.* 3. **To give warnings or advice:** * *If you touch that wire, you will get a shock.* * *If you have a problem, you should ask for help.* Emphasize that the 'if' clause uses the present simple, even though we are talking about the future. The 'will' is only in the main clause.

Guided practice

1. **Sentence Completion (5 minutes):** Provide students with sentence halves and have them match them. * If I miss the bus, ... (I will be late for work.) * If she studies hard, ... (she will pass the exam.) * We will go for a picnic ... (if the weather is nice.) * He won't finish the project ... (if he doesn't start soon.) * If you eat too much candy, ... (you will feel sick.) 2. **Gap-Fill with Verbs (5 minutes):** Give students sentences with blanks in both clauses and a verb in parentheses. They must put the verbs into the correct form (present simple or 'will' + base form). * If I (have) _____ time, I (visit) _____ my grandparents. (If I have time, I will visit my grandparents.) * She (not go) _____ to the party if she (feel) _____ tired. (She won't go to the party if she feels tired.) * If you (not hurry) _____, you (miss) _____ the train. (If you don't hurry, you will miss the train.) * They (buy) _____ a new house if they (get) _____ a promotion. (They will buy a new house if they get a promotion.)

Freer practice

1. **Chain Story (10 minutes):** Start a story with a first conditional sentence, e.g., 'If I win the lottery, I will buy a big house.' The next student must continue the story with another first conditional sentence, using the previous student's result as their condition. E.g., 'If I buy a big house, I will need a lot of furniture.' Continue around the class, encouraging creativity and correct conditional usage. 2. **Future Predictions (10 minutes):** Provide students with various hypothetical situations and ask them to make predictions using the first conditional. * 'What will happen if you don't study for the next English test?' * 'What will you do if your favorite team wins the championship?' * 'What will happen if the internet stops working for a day?' * 'What will you do if you have a free evening next week?' * 'What will happen if the global temperature continues to rise?' Encourage them to explain their reasoning.

Wrap-up

Review the main points: when we use the first conditional (real future possibilities), and its form (If + present simple, will + base verb). Ask students to complete the following sentence individually and share with a partner or the class: 'If I remember everything from this lesson, I will...' (e.g., 'feel confident using the first conditional', 'be able to make plans better'). This helps them reflect on their learning and apply the structure.

Planning for the Unexpected: A Weekend Dilemma

The alarm clock blared at 7 AM, signaling the start of Saturday. Maria stretched, feeling excited about her plans. She had arranged to meet her friend, Leo, for a hike in the nearby national park. If the weather was good, they would spend the whole day exploring the trails and enjoying a picnic lunch. However, Maria glanced out the window, and her heart sank a little. Dark clouds were gathering on the horizon. “Oh no,” she muttered. “If it rains, our hiking plan will be ruined.” She quickly grabbed her phone and texted Leo: “Hey, are you looking at the sky? If these clouds bring rain, what should we do?” Leo replied almost immediately: “Yeah, it doesn’t look great. If it starts to pour, we definitely won’t be able to hike. But don't worry, we can always make a new plan. If the weather clears up by noon, we could still go to the smaller park downtown.” Maria thought about the alternatives. If they couldn’t hike, they would have to find something else to do. She considered a few options. “If we go to the cinema, we will miss out on the fresh air,” she thought. “But if we stay home, we might get bored.” She remembered a new art exhibition that had just opened. “If Leo is interested, we could visit the art gallery,” she mused. “It’s indoors, so if the rain continues, it will be a perfect activity.” Just then, her phone buzzed again. It was Leo. “I just checked the forecast. It says there’s a 70% chance of heavy rain until late afternoon. So, if we want to do something fun, we'll need an indoor option.” Maria quickly typed back: “How about the new art exhibition? If you like modern art, you’ll really enjoy it. And if we get hungry afterwards, there’s a great café next door.” Leo responded with a smiley face emoji. “Perfect! If we go to the gallery, I will meet you there at 10:30 AM. If I leave now, I should get there on time.” Maria smiled. Even if their original plans changed, they would still have a wonderful Saturday. She knew that if you are flexible, you can always find a way to make the best of any situation. If she had learned one thing, it was that unexpected changes often lead to new and exciting experiences.

Grammar — First Conditional Sentences

The First Conditional is used to talk about possible future events and their likely results. It describes situations that are real or very probable. We often use it when we are making plans, predictions, or giving warnings and advice. The structure is: **If + present simple, will + base form of verb.** For example: *If I study, I will pass the exam.* (Studying is a real possibility, and passing is the likely result.) You can also reverse the clauses: **Subject + will + base form of verb if + present simple.** For example: *I will pass the exam if I study.* Notice that when 'if' is in the middle, we don't use a comma. Remember that 'will' is only in the main clause, never in the 'if' clause.

  1. Complete the sentences using the correct form of the verbs in parentheses (First Conditional).
    Answer: 1. If I (find) **find** her address, I (send) **will send** her an invitation. 2. If it (rain) **rains** tomorrow, we (not go) **won't go** to the park. 3. You (pass) **will pass** the exam if you (study) **study** hard. 4. If he (not hurry) **doesn't hurry**, he (miss) **will miss** the bus. 5. They (buy) **will buy** a new car if they (get) **get** a bonus. 6. If she (feel) **feels** sick, she (see) **will see** a doctor. 7. I (call) **will call** you if I (need) **need** help. 8. If we (not leave) **don't leave** soon, we (be) **will be** late. 9. She (be) **will be** very happy if she (win) **wins** the competition. 10. If you (touch) **touch** that, you (get) **will get** a shock.
  2. Rewrite the sentences, starting with 'If'. Remember to add a comma if necessary.
    Answer: 1. I will travel the world if I win the lottery. → **If I win the lottery, I will travel the world.** 2. She won't come to the party unless you invite her. (Use 'if you don't invite her') → **If you don't invite her, she won't come to the party.** 3. You will get good grades if you do your homework. → **If you do your homework, you will get good grades.** 4. We will have a picnic if the weather is sunny. → **If the weather is sunny, we will have a picnic.** 5. He will be tired tomorrow if he doesn't sleep now. → **If he doesn't sleep now, he will be tired tomorrow.**
  3. Correct the mistake in each first conditional sentence.
    Answer: 1. If I will have time, I visit you. → **If I have time, I will visit you.** 2. She will be angry if he won't call her. → **She will be angry if he doesn't call her.** 3. If it is sunny, we go to the beach. → **If it is sunny, we will go to the beach.** 4. You will get a cold if you don't wear a coat. → **Correct.** 5. If they will study more, they will pass the test. → **If they study more, they will pass the test.**

Pronunciation
