Using games in language teaching can help sustain learners' interest and effort over an extended period of time. Games create meaningful contexts for language use, allowing learners to understand language and express themselves in order to participate. This makes the language more vividly experienced and better remembered. Games are thus central to a teacher's repertoire rather than just occasional activities. They provide intensive, engaging practice of language skills while being fun. Effective games are chosen based on factors like class size, level, and topic to achieve learning goals while maintaining motivation.
