A free mathematics resource pairing student and teacher books with maps of Brazilian curriculum skills and their prerequisites.

Landing page captured for the 2026-11-14 issue.
For
Brazilian mathematics students and curriculum educators
Worth noticing
Its 138 prerequisite links each include a reason; high-school skills are grouped across the three-year stage because the BNCC does not assign them to a specific year.

Field notes

The page explains how Brazilian curriculum documents relate, distinguishing the BNCC’s required skills from laws governing school structure, recent high-school changes, and local curricula. Its map also reaches back to twelve preschool objectives that later skills use, even though preschool is not organized as a textbook subject. The homepage links to separate student and teacher books and describes the dependency relationships as reasons, rather than presenting only a sequence of skill codes.
