The explorations in this book include such tasks as determining the coins in piggy banks, matching two-dimensional shapes with three-dimensional solids, and organizing data about hats in tree diagrams. Students apply mathematical ideas from the five main content areas–number, algebra, geometry, measurement, and data analysis. As they work, they infer, generalize, reason by analogy, recognize relationships, and make representations, and they also guess, check, and revise and verify their results. The supplemental CD-ROM features interactive electronic activities, master copies of activity pages for students, and additional readings for teachers.
