How this map was made

Every connection is PRISM's own, written against OSPI's 2026 wording, with the reason for it. They were written by an AI ahead of time and are marked until a teacher has read them, so treat them as a starting point. The idea of a map like this comes from Achieve the Core's Coherence Map for Common Core math.

Standards text, priority flags, the Common Core crosswalk and the linked resources are published by the Washington Office of Superintendent of Public Instruction (OSPI). PRISM is an independent tool, not affiliated with or endorsed by OSPI. The Standards for Mathematical Practice text is from the Common Core State Standards.
