Classmates can only answer yes / no to his questions. Thus, the pupil asks, for example, whether it is made from batter, whether it is filled with some cream, whether it has some icing and so on. In this way, he tries to guess which dessert it is, and when he guesses, the roles change and someone else goes to guess again. It is a perfect way for students to realize what the dessert consists of and they can then use this knowledge further.
