Third Conditional and Mixed Conditionals ESL Lesson Plan (B2, 60 Minutes)

A complete 60-minute B2 lesson on Third Conditional and Mixed Conditionals, built round the theme "Turning Points".

  • CEFR B2
  • 60 minutes
  • Teenagers and adults
  • Grammar
  • Conditionals
  • Third Conditional and Mixed Conditionals

About this lesson

Who it is for. Upper-intermediate students who are confident with the first and second conditionals. They try to talk about past regrets with the second conditional (If I studied harder, I passed) or with would in both clauses (If I would have known, I would have come).

Everything the lesson needs is on this page: the language analysis, the timed stages with the teacher's own words and instruction-checking questions, the differentiation, the printable handouts and the answer key.

Aims

Main aim. To develop students' use of the third conditional for imaginary past situations and mixed conditionals for past causes with present results (and present states with past results).

Learning outcome. By the end of the lesson, students can tell the story of a turning point in their life and imagine how things would be different, e.g. If I hadn't missed the bus, I wouldn't have met my best friend, and I wouldn't be so happy now.

  • Subsidiary aim. To practise the weak forms in would have /ˈwʊdəv/.
  • Subsidiary aim. To develop fluency in telling a personal story about a turning point.

Language analysis

What to know before the lesson: the meaning, form and pronunciation of the target language, and the problems learners usually have with it.

Form

TypeIf clauseMain clauseExample
ThirdIf + past perfectwould / could / might have + past participleIf I hadn't missed the bus, I wouldn't have met her.
Mixed (past → present)If + past perfectwould / could + base verbIf I hadn't met her, I wouldn't be so happy now.
Mixed (present → past)If + past simplewould / could have + past participleIf I were braver, I would have applied for the job.

Form: notes

  • Contractions in speech: If I'd known (= had), I'd have come (= would). I wouldn't have /aɪ ˈwʊdnt əv/.

Meaning and use

  • Third: an imaginary past. The real past is the opposite: If I had studied, I would have passed = I didn't study; I didn't pass.
  • Used for regrets, criticism, relief and speculation about the past.
  • Mixed (past → present): an unreal past cause with an unreal present result.
  • Mixed (present → past): a present (permanent) state with an unreal past result.

Pronunciation

  • would have is weak: /ˈwʊdəv/ or /ˈwʊdə/. wouldn't have /ˈwʊdntəv/. could have /ˈkʊdəv/.
  • The contracted 'd can mean had (in the if clause) or would (in the main clause): If I'd known, I'd have come.

Concept-checking questions

  • If Amaya hadn't missed the bus, she wouldn't have met Kavindu. Did Amaya miss the bus? (Yes.) · Did she meet Kavindu? (Yes.) · Is this about the past or the present? (The past.)
  • If she hadn't met him, she wouldn't be a chef today. Is she a chef now? (Yes.) · When did the meeting happen? (In the past.) When is the result? (Now.)

Anticipated problems and solutions

ProblemSolution
would have in the if clause (If I would have known).Board the pattern; cross out would in the if clause.
Confusing 'd (had / would).Colour-code: 'd + past participle in the if clause = had; 'd have = would.
Students can't hear or say would have.Back-chain drill: met her → have met her → wouldn't have met her.
Mixed conditionals seem confusing.Use timelines with two points: PAST cause → NOW result.

CEFR B2 · 60 minutes · Teenagers and adults

Procedure: Third Conditional and Mixed Conditionals, step by step

Warm-up5 minutes · Pairs, then whole class

Aim: To introduce the theme of chance and turning points.

Tell a short true or invented story: "Ten years ago, I nearly became a doctor. But I failed my biology exam, so I studied English instead, and I became a teacher."

Ask: "Was failing the exam bad luck or good luck?" Pairs discuss small moments that changed something in their lives (2 minutes).

Take one or two examples.

Presentation20 minutes · Individual, pairs, whole class

Aim: To present the third and mixed conditionals in context and clarify their meaning, form and pronunciation.

Part A: Reading (6 minutes)

Give out Handout 1. Say: "Read the article. What was the turning point in Amaya's life? Three minutes."

Pairs compare. Students answer the three questions. Check as a class.

Part B: Noticing (4 minutes)

Say: "Underline every sentence with if. For each one, decide: is it about the past, the present or both?" Pairs compare.

Part C: Clarification (10 minutes)

Third conditional. Board If Amaya hadn't missed the bus, she wouldn't have met Kavindu. Ask the CCQs. Show the real past next to it: She missed the bus. She met him.

Elicit the form: If + past perfect, would have + past participle. Cross out would in If she would have ...

Mixed conditional. Board If she hadn't met him, she wouldn't be a chef today. Ask the CCQs. Draw a timeline with two points: PAST cause → NOW result.

Show the other mixed type briefly: If she weren't so brave, she wouldn't have opened a restaurant.

Point out 'd = had or would.

Pronunciation. Back-chain drill: met him → have met him → wouldn't have met him → If she hadn't missed the bus, she wouldn't have met him.

Controlled practice10 minutes · Individual, then pairs, then whole class

Aim: To practise the forms accurately.

Give out Handout 2. Say: "Read the reference box. Do Exercise A: write a conditional sentence for each situation. Then Exercise B: choose the correct form. Seven minutes."

Pairs compare. Check as a class, asking: "Past result or present result?"

Fast finishers do Handout 3 (further practice); otherwise set it for homework.

Freer practice18 minutes · Individual, then pairs, then groups

Aim: To use the forms fluently in a personal story.

Give out Handout 4. Students choose a turning point in their life (or invent one) and make notes in the planner (4 minutes).

ICQs: "Does it have to be true?" (No, it can be invented.) "Do you write full sentences?" (No, notes.)

Pairs (6 minutes). Students tell their story. The listener asks at least two What would have happened if ...? questions.

Groups (6 minutes). New groups of three. Students retell their partner's story using the third and mixed conditionals: If Ruwan hadn't broken his leg, he wouldn't have started painting, and he wouldn't be an artist now.

The class chooses the most surprising turning point (2 minutes).

Monitor and note language use.

Feedback and wrap-up7 minutes · Whole class

Aim: To give feedback and consolidate.

Board sentences heard in Stage 4 (correct and incorrect). Students correct the errors.

Ask: "When do we use the third conditional? When do we use mixed?"

Set the homework.

Homework Complete Handout 3. Then write a 180-word blog post about a turning point in your life or in the life of a famous person. Use at least three third conditionals and two mixed conditionals.

PPP (presentation, practice, production). Stage times add up to 60 minutes.

Differentiation

Support
Give weaker students the timelines on a card. Provide sentence frames: If I hadn't ..., I wouldn't have ... · If I hadn't ..., I wouldn't be ... now.
Stretch
Stronger students use could have, might have and If it hadn't been for .... They use the present → past mixed type: If I weren't so shy, I'd have spoken to her.

Adapting the lesson

ForWhat to change
A large class (40 or more)Keep the pairwork in "Freer practice" in fixed pairs rather than a mingle, and take feedback from four or five pairs instead of the whole room. Run "Pairs" once, with two pairs reporting, rather than hearing every pair. Monitor one half of the room during "Controlled practice" and the other half during "Freer practice".
A class with no photocopierPut the exercises from Handout 2: Language Focus and Practice on the board for learners to copy into their notebooks, and read any text aloud twice instead of printing it. The board plan above is this lesson's minimum - with that on the board, it runs on no paper at all.
An online classSend Handouts 1 to 4 in the chat before the lesson and put the board plan on a shared slide. Use breakout rooms for "Pairs" and visit each room once. Have learners type the controlled answers in the chat, so you see every answer at once instead of nominating.
A different age groupWith teenagers, shorten the analysis and get to the task sooner. With adults in a work context, keep the forms exactly as they are and swap the lesson's theme for one from their own field.

Checking learning

In the story task, students use the past perfect after if and would have + past participle accurately. Students produce at least one mixed conditional with a present result. 5 out of 6 or better on Handout 2, Exercise B.

Teacher's reflection

Did students hear and produce the weak form of would have? Was the mixed conditional clear after the timelines?

Handout 1: Magazine Article

Name: ______________________________ Date: ______________

ONE MISSED BUS, ONE NEW LIFE

Eight years ago, Amaya Wickramasinghe was a shy accounting student in Kandy. One rainy morning, she missed the bus to university by thirty seconds. While she was waiting for the next one, she started talking to a young man at the bus stop. His name was Kavindu, and he was a chef.

"If I hadn't missed that bus, I would never have met Kavindu," Amaya says. "He invited me to his restaurant, and I fell in love with cooking." She left accounting and trained as a chef. If she had stayed at university, she would have become an accountant like her father.

Today, Amaya runs her own restaurant in Galle. "If I hadn't met Kavindu, I wouldn't be a chef today, and I probably wouldn't be so happy," she says. "And if I weren't so stubborn, I wouldn't have opened my own restaurant. Everyone told me it was a bad idea!"
