Grammar is a progressive series of four illustrated books for schools where English is taught from an early age. Besides introducing some new topics, Grammar Four revises the grammar that has been taught in the series already. It is therefore suitable not only for learners who have read the earlier books but also for those who have not. Grammar Four contains: Short texts showing how each structure is used. Grammar notes. Oral and written exercises. Activities and pairwork. There is an accompanying Teacher`s Book which provides answers to the exercises, advice on how to use them, ideas for additional activities, and tests.
