This is a very interesting mother tongue textbook. It discusses a set of topics particularly relevant to students of this age: sports, theatre, music, design, as well as linguistics.
Although this is a language textbook, graphics, tables and films are extensively used.
The textbook efficiently teaches learners how to communicate via text, speech, even how to efficiently read newspapers etc.
Another very valuable aspect of the textbook is its contribution to the socialisation of learners.
