Dive Brief:

• According to EdReports.org, textbooks that support "Everyday Math," a popular K-6 math curriculum, and three other mathematics curricula has been found to be unaligned with current Common Core standards.
• Approximately  200,000 classrooms use Everyday Math, which didn't meet standards for any grade level.
• Education Week reports the publisher of the textbook, McGraw-Hill, disagreed with the new findings, saying that the EdReports.org review was "incomplete, inaccurate, and misleading." 

Dive Insight:

Districts reacting to the news about Everyday Math should understand the feedback in context. This is far from the first time that more than one widely-used curriculum hasn't met Common Core standards. Last March, EdReports.org also conducted a review for Common Core standards alignment, after finding 85%, or 17 of reviewed K-8 math textbooks did not align with the Common Core standards.

Pearson, McGraw-Hill and Houghton Mifflin Harcourt were all involved in that review, and like today, the publishers pushed back, criticizing the review methodology. Yet even if the veracity of the EdReports evaluations, which are backed by the Bill and Melinda Gates Foundation, are pristine, many still question whether or not the Common Core math standards are flawed  in the first place. Some experts and educators think the math standards try to cover too much material, don't have enough depth for college readiness, or skip entire skills all together, Education Week previously reported.
