The game can be played with a whole class, where two learners share one card; or with a group of 16 learners; or with a smaller group, where a learner holds more than one card. To start, a learner says the second part of their card. The learner with the equivalent expression reads the answer, and then the second part of their card. Play continues until the loop is formed.
