K–8 Math Materials Spotlight: Understanding the Landscape in Three Charts

Summary

With an increasing number of supplemental math resources in K–8 classrooms, districts face challenges in maintaining instructional coherence. While most districts select a single core curriculum, they often layer multiple supplemental products, making it harder to ensure a clear, connected learning experience for students.

Key Learnings:

• Supplemental Math Materials Are Outpacing Core Curriculum: Districts have numerous options for supplemental math products compared to a narrower list of choices for high-quality, aligned core curriculum materials.
• Multiple Supplements Are the Norm: Over 60% of districts use more than one supplemental resource for K-8 math, and 30% use four or more.
• Supplements Are Shaping How Students Learn: Four of the top ten most-selected math materials by districts are supplemental products, with one product reaching more districts than any core curriculum in the CEMD dataset.
