The Illustrative Mathematics Resource Hub is a free online platform that hosts teacher facing materials, tasks, and planning tools for the Illustrative Mathematics curriculum in grades K to 12. Created by the nonprofit Illustrative Mathematics organization, which was founded by mathematician William McCallum and colleagues, the hub offers problem based lessons, student tasks, and teacher guidance that emphasize conceptual understanding and discourse. Homeschool parents can browse full units, download printable student pages, and view sample lesson plans to adapt for one child or small groups. Families use the hub when they want a high quality, standards aligned math spine that focuses on reasoning and real problem solving rather than rote practice.
