Textbooks Out of Synch with Common Core

School districts nationwide are struggling to find textbooks that are aligned with the rigorous Common Core standards for math and English Language Arts. Some critics say that's because the controversial standards have outpaced resources.

According to a recent study by the Education Week Research Center, fewer than one-third of teachers nationwide say their textbooks are aligned with the Common Core standards. But Richard Weisenhoff, Baltimore County's executive director of academics, says publishers tell a different story.
