"World Class" is a three-stage course for young teenagers who have already studied at least two years of primary English. The course takes students from elementary through to upper-intermediate level. Each stage provides 90-100 classroom lessons and there are 6 modules, 48 lessons in total. Each level consists of a student's book, activity book, teacher's book and a class cassette. This activity book at level 1 provides consolidation of both new language and structures learnt at primary school. It also contains self-check tests to help students monitor their own progress and take responsibility for their own learning. The theme-based modules combine facts about the real world with elements of fantasy and fun. Students explore the themes and relate them to their own lives. Each lesson has a different format and focus, and there is a great variety of texts, topics and activities. The emphasis on skills work gives students the opportunity to develop fluency. Active language-focus sections motivate students to discover for themselves how the language works. Each module concludes with a comprehensive revision of language items presented in previous seven lessons. Language games, puzzles and quizzes are included to provide fun and relaxation in the classroom.
