Activities that promote "active thinking" help children learn mathematics and science by allowing them to work at forming relationships, making connections, and integrating concepts and procedures. Dynamic and exciting children's books invite and motivate children to learn mathematics and science by responding to stories, characters, and their experiences. This paper presents an investigation on how students are able to connect mathematics, science, and literature using the Hush-a-bye Babies. The primary focus is on understanding the meaning of environment and habitat--more specifically, how habitat and environment differ for different living things. The overall goal is to encourage the use of higher level thinking skills (synthesis, analysis, and evaluation). The author gives suggestions on how a teacher can introduce a book, share a book and promote concepts to students. (Contains 8 online resources.)
