Over the last several years, Common Core education standards have become an increasingly important issue for parents and teachers, as they see how children are affected by the policy.

In the face of slick advertising campaigns by Common Core’s corporate backers and lofty speeches from politicians, the truth can be difficult to ferret out. With the new book, “Common Ground on Common Core,” we finally have a handy, one-volume resource that answers all these questions and more.
