This is one of my all time favorite activities for pre-intermediate to intermediate learners.
Students work in pairs first they look at three animals that were created by adding two pictures together in photoshop. They then have to give the animal a name and describe it by filling in the blanks.
after they are finished students change partners and describe their animals. As a final productive activity students can be asked to make up their own new animal. I have ended up with some beautiful student artwork and language from this exercise and will put some samples up in the future.
