By the end of the lesson, students will be able to:
The 10 phrases describe actions and feelings from a typical music lesson — A2 level. Cover-and-test: students cover the right column and recall the meaning. Pronunciation: concentrate /ˈkɒnsntreɪt/ (stress on first syllable), nervous /ˈnɜːvəs/. Concept-checks: "Do you feel nervous before an easy test or a hard one?" / "Do you knock on the door before you go in?" After Part A, ask: "Which of these do you do in class?" Part C optional.
Past Progressive is the central structure of this lesson. The contrast table (navy = PS / rose = PP) is the key visual. Teach the two uses of Past Progressive clearly before the exercises:
(1) Action in progress at a specific past time: "At 6pm yesterday, she was playing the piano."
(2) Background action interrupted by a Past Simple event: "She was playing the piano when the phone rang."
When vs while: when introduces the short interrupting action (PS) — "when the phone rang"; while introduces the longer ongoing action (PP) — "while she was playing". Both halves of the sentence describe the same moment, but when goes with PS and while goes with PP.
Common errors: "She was play the piano" (missing -ing) / "While the phone rang" (while + PS is wrong in this pattern) / "She was playing when she was making a mistake" (interruption must be PS, not PP).
The text (~130 words) uses only Past Simple and Past Progressive. Gist: Anna had a difficult piano lesson with several interruptions. T/F/NG answers: 1 T · 2 F (her teacher was reading a book, not sleeping) · 3 T · 4 NG (no mention of the weather) · 5 T ("Anna was feeling very nervous when she started"). Push students to use both tenses in their answers.
The script uses only Past Simple and Past Progressive. Read at a clear A2–B1 pace. The natural dialogue shows both tenses in context — PP for what was happening, PS for what happened suddenly. Task 1 answers: 1-B (she was practising a new piece) · 2-C (her little brother knocked on the door) · 3-A (she was feeling very nervous). Task 2: (1) new piece · (2) mistake · (3) knocked · (4) concentrating · (5) nervous.
The role-play asks students to describe a past scene using both tenses — PP for what was happening in the background, PS for what suddenly happened. This is the most productive practice context for the PS/PP contrast at this level. Monitor for: correct use of when vs while, PP form (was/were + -ing), and PS as the interrupting event. Delayed feedback after the task.
Students write about a memorable or funny moment from their own life. The text needs PP for the background scene and PS for the sudden event — this is exactly the PS/PP contrast in its most natural context. Encourage: start with the background scene ("I was sitting in class …"), then introduce the interruption ("when suddenly …"), then describe what happened next (PS). The self-check box covers both tenses, when/while, and vocabulary.
