Most Math Curricula Found to Be Out of Sync With Common Core

The first round of a Consumer Reports-style review for instructional materials paints a dismal picture of the textbook-publishing industry’s response to new standards: Seventeen of 20 math series reviewed were judged as failing to live up to claims that they are aligned to the common core.

The reviews, released online Wednesday by the nonprofit EdReports.org, were conducted by small groups of teachers and instructional leaders from across the country. They looked at digital and print K-8 mathematics materials from widely used publishers—including Pearson, McGraw-Hill, and Houghton Mifflin Harcourt—as well as from some lesser-known providers whose texts passed state review processes. The results echo previous alignment studies conducted by university-based researchers.
