This document discusses using games in the classroom for CLIL (Content and Language Integrated Learning) lessons. It provides reasons for using games, such as offering flexibility, promoting interdependence and independence, helping break down barriers between subjects, and generating student interest and engagement. However, it notes games should only be used if the objectives are well-defined, the game is appropriate, fun for students, and easy for them to play with clear learning purposes. Educators should consider the language, age, timing, grouping, student background, materials, and type of game. It provides examples of game websites for different ages and lesson examples that use games.
