The Algebra 1, Geometry, and Algebra 2 series features real-world explorations based on the STEM research of National Geographic Explorers who demonstrate how mathematics applies to their unique professions. Students meet a National Geographic Explorer at the beginning of each chapter to learn how they apply mathematics in their profession with an Everyday Explorations video. Throughout each chapter, students develop their mathematical skills by following the Explorer’s research and creating STEM connections. This culminates in an end-of-chapter Performance Task to keep students connecting math to the real world.
