Provides a syllabus progression from elementary to upper-intermediate level. It takes a structured approach to grammar. Grammatical structures are introduced in context, with questions that encourage students to work out the rules for themselves. A "Grammar section" at the back of the student`s books provides a reference before, during or after the lesson. A vocabulary syllabus concentrates on three key areas: learning new words in lexical sets; acquiring good habits for learning vocabulary; and developing vocabulary "systems" such as sound and spelling relationships. Integrated skills work is an important feature of the course. In every unit the reading and listening activities contextualize and bring together much previously introduced language. Students develop fluency and accuracy in all four skills. Supportive teacher`s books at each level include an explanation of the methodology, step-by-step lesson guidance, additional activities, photocopiable tests, cultural notes, and detailed answer keys.
