This book supplements the instructional and hands-on activities used in the classroom. The book builds upon the students' understanding of patterns and of "more" and "less" by showing systematic ways of displaying and organizing data, as well as making predictions and observations based on this data. Spinners, games, and riddles are used to reinforce the concepts of probability, statistics, and graphing. Activities are designed to be completed by individuals, in cooperative groups, or as a class.
