To ensure they're meeting state early learning guidelines for science, preschool educators need research-based ways to teach young children about scientific concepts. This title helps children ages 3-5 investigate their everyday world and develop the basics of scientific thinking - skills they apply across subject areas when they enter school.

The authors report the results of some half dozen years of research into when and how children acquire numerical skills. They provide a new set of answers to these questions, and overturn much of the traditional wisdom on the subject.
