This document contains 16 question strips that can be used for classroom activities focusing on the grammar structure "used to". The questions prompts students to ask about habits, locations, hobbies, and daily activities from the past to elicit language using "used to". The document provides instructions for three activity formats: having students work in pairs or groups to ask and answer the questions; having individual students find new partners to ask their question to and exchange questions; and a variation where students must memorize the question before finding a new partner.
