The student’s book has 6 units organized into the following: • Beginning of the unit where students become familiar with the content in a communicative way; • Vocabulary exercise book where the lexicon of the unit is systematized and expanded; • Grammar exercise book where the rules are presented and put into practice with various activities; • Conecta2 where the contents are practiced in a digital and current context; • How Interesting! where cultural aspects are worked on; • Review! Through self-assessment exercises, different skills are worked upon. Each block ends with a section to practice DELE school tasks, a game board to review the contents of the 3 units of the block and a final project. A visual dictionary and a spelling and grammar appendix are included at the end of the book.
