A B1-level Business English lesson on writing cover letters, ideal for learners preparing for job applications or international careers. Based on an adapted article from Indeed, students identify common cover letter mistakes, correct a bad model, and analyse a good version to understand the four key parts: Introduction, Motivation, Suitability, and Closing. The lesson includes reading for gist and detail, error correction, guided writing practice, and peer feedback, finishing with a discussion on whether cover letters are still relevant today. Clear, practical, and engaging, this lesson helps students build both language skills and real-world career confidence.
