This is a whole class speaking activity. There are 16 unique sets of twins (all 4 pictures are the same, but in a different order). Each student will get 1 sheet with 4 pictures on it. Students mingle until they find their twin. All communication should be in the target language. This may be adapted for any level class that has the vocabulary for these 10 expressions: hot, cold, hungry, thirsty, right, wrong, age, sleepy, ashamed, afraid.
