Written for all teachers of young children, this book illustrates activities that promote early mathematics development for children ages three to five and "showcases" mathematics for the young child. The thirty-five activities in this book are distributed into five content areas: number and operations, geometry, algebra, measurement, and data analysis. The content areas are connected by a continuing story, "Hanny the Honey Bear Discovers the World of Mathematics in the Big Zoo." Teachers can use this book to help themselves teach mathematics, learn mathematics, and most important, "listen to children think!" This book is divided into the following six sections: (1) Introduction; (2) Number and Operations; (3) Geometry; (4) Algebra; (5) Measurement; and (6) Data Analysis. Appended are: (1) Selected Expectations from "Principles and Standards for School Mathematics" (NCTM 2000); (2) Early Childhood Mathematics: Promoting Good Beginnings: A Joint Position Statement of the NAEYC and the NCTM; (3) Templates for Animal Stick Puppets; and (4) Templates for Creature Cards. A list of references concludes the book.
