This is a nice little info gap exercise in which students ask about things people are planning in the future. It can be used with any future marker.

E.g. What are you going to do tonight? What will you do next week? What are you planning for your next holiday?

The one the teacher chooses is based on the grammar and vocabulary that has been covered in class. Ideally this activity should be rounded off with a personalization activity. where students talk or write about their future plans.
