It works for all levels of English, and most class situations. Each pair has 15-20 minutes to draw a blueprint of their dreamhouse. They should try to make it as detailed as possible. Each pair presents their dreamhouse to the class, explaining how many rooms, the type of rooms, furniture, special features, etc. Give each pair 5 minutes to make their presentation.
Students choose one room and cut out pictures from magazines to decorate it.
Then they give an in-class presentation explaining why they chose what they did.
