Learning progressions chart a path forward.

Core Progress learning progressions for math tell you what students know and what they are ready to learn next on an empirically validated learning continuum. They map the inter-related prerequisite skills needed to further conceptual understanding and provide resources to help students achieve mastery. Two editions are available in STAR Math—Core Progress and Core Progress for Common Core—to optimize alignment with each state’s standards.
