These cards go along with these flashcards: http://en.islcollective.com/resources/printables/worksheets_doc_docx/comparative_questions_flash_cards/comparison-board-games/67743 , but not necessarily. Everytime a student gets a pair, they must make a sentence using the comparative form of the adjective. For example: they get BIG - BIGGER. There are pictures of a house and an appartment building. In order to remove the cards from the table, the student must say: "An apartment building is bigger than a house."
