• Quick retrieval from earlier learning (The subjunctive: if I were, I wish it were, I suggest she be; Mixed conditionals: past cause, present result (and vice versa)). Students answer on mini whiteboards.
• Show answers together and note who needs support in the main task.

1. Is this sentence correct in formal written English? If she weren't afraid of heights, she would have joined the climbing trip last summer. (correct / incorrect) → correctPrompt: Look for time words: now, today, yesterday, last week. Which half is past and which is present?
2. Choose the correct verb form for formal English. The coach insists that every player ___ on time. (be / being / is / was) → bePrompt: Is it imaginary (if, wish, as if)? Or a demand/suggestion (insist, suggest, essential that…)?

(It is important that he arrives early tomorrow will. / It is important that he arrived early tomorrow. / It is important that he arrive early. / It is important that he arriving early.) → It is important that he arrive early.Prompt: Look for if, wish, as if, or a verb like ask/insist/suggest + that.

• Show a sentence with the grammar point used wrongly and ask what sounds odd.
• Share the objective: Advanced subjunctive: were it not for, lest, that she not be. Read the success criteria together.

• Work through the example out loud, saying why you do each step, not just what you do.
• Example: Choose the form that is correct in formal written English. ___ I known about the storm, I would have stayed at home.
• Step 1: Formal English keeps the subjunctive after verbs of demanding and suggesting, in inverted conditions (Were it not, Had I known, Should you need) and in fixed phrases.
• Step 2: Inverted third conditional: 'Had I known' = 'If I had known'.
• Step 3: Put it back into the sentence and read it aloud: "Had I known about the storm, I would have stayed at home."
• Step 4: So the answer is: Had
• Answer: Had
• Pause after each step and ask a student to say what comes next.

• Do these together. Students try each step on whiteboards before you reveal it.
• Use the hints as prompts rather than giving the answer.
