This book provides a balance of discovery learning and direct instruction. The covered topics are based primarily on those stated in the NCTM Data Analysis and Probability Standards and the Common Core State Standards for K-8 Data and Measurement Curriculum. All activities follow the four step outline presented in the GAISE document. Activities and exercises address the range of learning objectives appropriate for future teachers with a balance of conceptual understanding and computational fluency. A rich collection of interdisciplinary exercises of varying degrees of difficulty is integrated within the text. The workbook is primarily intended as the text for a data analysis course for pre-service elementary and middle school teachers. It can also be used as a text for a data analysis course that will be part of a mathematics endorsement and as a resource and reference for in-service faculty development.
