A persistent problem area for students is phrasal verbs. This story activity presents the verbs in a context helping the students to work out the meaning. It is also memorable so it's easier for students to remember them too.
Discussion wheels are a good way of giving students time to think and formulate opinions before they do discussion work. They work particularly well with areas of discussion which can have ranges of agreement or disagreement.
The activity should work at most levels above elementary, as long as your students have some knowledge of past tenses, but it works best when they also know past continuous / progressive too. All you need to get things started is a sheet of plain paper for each pair of students.
