The problem with most social studies textbooks is that they lack the content K-3 students need to develop basic social understandings—despite the fact that this is one of the goals of most state and district curriculum guides. With this series, Janet Alleman and Jere Brophy offer a better alternative. They provide units structured around powerful ideas, developed in depth with applications to outside life, creating a far more substantive program than any major textbook can support. This is a three-volume series in which the authors present instructional units on cultural universals for the primary grades.
