Brazilian Portuguese grammar book. This book is divided in four short books/chapters. Book 1 -Present Tense (first steps), Book 2 -Present Tense (foundation), Book 3 -Present, Present Continuous, Immediate Future, Simple Future and The Imperative form. Book 4 -Simple Past Tense. It is designed to help students to achieve an intermediate level in 4-6 months with a 1h lesson a week, if used by a teacher. Students using 'DIA A DIA' will be able to hold basic conversation using past, present and future. This book has been carefully prepared to help foreign students to learn the most used tenses in day to day situations, in an easy, fast and fun way. The book itself is a tool that will help teachers during their Portuguese language classes. It was developed over the past 13 years, addressing the needs and difficulties encountered by those who wish to learn the Portuguese language. The complete series, including other tenses and the use of the subjunctive, has 15 short books. ' DIA A DIA ' includes the first four short books needed to introduce the student to Portuguese and enable them to use the language with ease and efficiency. The teacher can use this book in many ways in order to speed up the student's learning process. It is necessary, however, for the addition of more information not included in the books, so the teacher can use their own intuition and give extra information according to their region in Brazil and also according to their students' needs. A simple example would be the case of the first pages of pronouns and verb ' TO BE ', which are presented in the correct manner but where during my classes I also explain the use of colloquial Portuguese: 'ce' instead of 'voce', 'to' instead of 'estou' the omission of 'Eu' and 'Nos' and the difference in the pronunciation of R and S in Rio and Sao Paulo . Should this book be used without the help of a teacher or from a native Portuguese speaker, the student should have some idea of the sound of the language or use other resources to help them, since at this time this book is not accompanied by audio"
