This course provides grammar practice for young learners from elementary up to pre-intermediate level considering ther age 13-15 years. It's especially valuable for its presenting grammar in different context relevant to young learners.

For those teachers who want their students to try and be more independent in their studies this book has a full grammar reference section. The author uses simple explaining language which,  nevertheless, is not simple enough for young learners. A teacher might use these explanations as a base for their own explaining formulas (but from my point of view better understanding of grammar is achieved when the teacher explains it in L1, not in English for elementary students.)

Anyway, this book is rather nice becausr it contains a range of activity types which suit different learning styles. It is good ad using a variety of interesting topics specially chosen for young students
