What children need to know to do well on standardized tests is one thing and what they need to do well in life is quite another. That’s where “Mind in the Making: The Seven Essential Life Skills Every Child Needs’’ (HarperStudio), published Tuesday, comes in. Author Ellen Galinsky, president of the Families and Work Institute, and her team interviewed 70 leading early- childhood researchers and reviewed hundreds of studies. Galinsky has written an accessible guide to help parents foster the development of social and emotional intelligence and teach their children to be engaged learners through everyday, playful activities. No fancy equipment required.
