Author Description

Well-planned units of study teach children to collect, display, and interpret data. Each book contains a complete unit requiring approximately 15 class sessions. Unique lessons help develop problem-solving and math communication skills -- areas stressed in the NCTM standards. The primary-level books emphasize the building blocks of data analysis: counting, measuring, sorting, and classifying. The upper-grade books continue to focus on real data and real problems, while carefully developing key concepts in statistics and graphing. Students learn to make reasonable inferences from a population sample. The activities introduce basic ideas about sample size, bias, and making inferences.
