In our increasingly global age, students not only need to learn English for international communication but should also become familiar with the languages of the world. The English classroom can be an exciting place to teach this linguistic awareness. This presentation will introduce ideas for designing a content-based thematic unit on "world languages and writing systems". It will argue that teaching about world languages can stimulate student interest in language, improve language learning motivation and promote international awareness while practicing English language skills. The presenter will demonstrate task-based EFL activities through which students explore language families, study world languages, learn to recognize major writing systems and practice basic conversation expressions in 7 world languages.
