This is a good exercise to introduce the present perfect simple for recently completed events. It’s best at the B2-C1 level.
- Choose two version of the same scene (google: find the difference images) or draw two simple versions of a house/office etc.
- Show the class the first picture and elicit what needs to be repaired, replaced or what other work needs to be done (the lawn needs to be mowed etc.).
- Then take the first image away and show the second where several things have changed (very recently). Elicit the changes by asking “What work has been done?”. TIP: you may want to include a person in the picture and give them a name. Elicit: “Thomas has mowed the lawn.” etc. OR you can focus on passive. Learners may need some prompting to come up with “The lawn has been mowed, The window has been repaired”.
- At some point they may ask questions about the form. Board the form using an example from the picture. Elicit the meaning and use through Concept Checking Questions.
Follow-up: As home practice have the learners find or draw two images. Ask them to write 10 true/false questions about picture B. When they bring them to class, they show the first picture for 1 minute. Then remove picture 1, then show picture 2 for 1 minute and then remove it. Then they quiz their classmates with their T/F questions (awarding points for each correct answer).
1-1: The activity works well for 1-1 as described above.
