- Brazilian mathematics students and teachers
- Worth noticing
- For high school, the map keeps skills in one column because schools—not the BNCC—choose the year in which each is taught.
Field notes
The page explains code formats such as EF01MA05 and EM13MAT303, including the point that “13” denotes the full high-school stage rather than a grade. It situates the map alongside the LDB, BNCC, the 2024 high-school reorganization, state and municipal curricula, and PNLD textbook distribution. The author also distinguishes preschool objectives from the grade-based textbook sequence and calls the map a national floor rather than a local pacing guide.
