The Prepara Brasil Collection was created to enable students to develop the curricular components of Portuguese Language and Mathematics, enabling them to undergo the assessments they will undergo throughout Elementary School. For teachers, the collection is a tool that makes it possible to measure the difficulties and abilities of students in these two curricular components, so that they can direct pedagogical actions that help children's performance and, consequently, that are assertive in improving assessment scores. such as those of the Basic Education Assessment System (Saeb).
