I have compiled a list of 15 problems to which students need to brainstorm solutions. This list is a result of classes I have taught to teenage and adult students. It is a perfect fit for conversation classes. The topics include: family life, relationships, neighbours, and shopping.
Students work in pairs or small groups trying to find solutions to 15 different problems. It is a good opportunity to practice the second conditional (I would…, If I were in this situation…), modal verbs (should, might, mustn’t etc.) and negotiating (agreeing/disagreeing/expressing your opinion/asking about your partner’s opinion).
I have used this activity both with adult and teenage students, levels intermediate – advanced. It works well as a warm-up (giving the students just one problem) to a regular class, and may also be used during conversation classes (takes around 20 mins.) Make sure to allow some time for the groups to present and compare their ideas at the end of class.
