Educational jurisdictions typically prescribe the content of mathematics curricula in print documents, often available as downloadable files. Digital maps provide another view of curriculum that can depart from the linear structure of these documents and more effectively convey the connections within school mathematics. In this chapter, we introduce three digital mapping projects: Math Mapper 6–8, the Dynamic Mathematics Curriculum Network and the Cambridge Mathematics Framework. Each project draws on distinct theoretical and methodological approaches, and the connections shown in each map are based on different sources. Despite these differences, each project seeks to enhance mathematics teaching and learning by visually representing connections, making the basis for those connections explicit, ensuring the map can be used in flexible ways and providing on-demand access to related instructional materials. Initial feedback from the intended audiences for each map reveals the ways each project can contribute to mathematics education. Some future directions for digital mapping of school mathematics that emerged through discussion of the challenges that arose across the projects are also offered.
