Based on market share and states’ recommendations, EdReports.org selected 20 math instructional series to review for common-core alignment. (For reporting purposes, K-5 and 6-8 texts from the same publisher were considered separate series.) Small teams of educators scored the digital and print texts on focus, coherence, rigor, and usability. In addition to individual grade-level ratings, EdReports.org gave summative ratings for each grade band (K-2, 3-5, and 6-8). Eureka Math was the only program that met the expectations for alignment to the Common Core State Standards at every grade level reviewed.
