This is the first of three books focusing on the 'mechanics' of the English language. Each book offers a systematic work and study programme for use in the classroom or at home. Book 1 provides an introduction to the basic principles of spelling, grammar and punctuation for students at key stage 2 and/or ESL learners. Each of the 30 units is divided into three sections. The tasks in Section A introduce the theme of the unit, and highlight any weaknesses that a student may have in that area. A reference section provides accessible explanations of the language points covered. Section B then tests whether the subject matter has been mastered, with tasks to extend, revise and consolidate knowledge. A glossary and answer key are also provided.
