Three collections of 9th grade textbooks were analyzed, used in two state schools in the city of Itaqui - RS. Thus, it was analyzed how the competencies and skills are being implemented in the books according to the BNCC. At the end of this research it became evident that the three collections have been adapting to the BNCC, bringing activities in line with the competencies and skills of the BNCC. Moreover, each one of them has its own particularities, some are more complete and more complex, involving more skills, and others are still with a more classical and traditional approach.
