This book follows students' natural progression from measuring with informal or nonstandard units to using standard units to measure such attributes as length, weight, angle and temperature. Activities extend students' learning to the measurement of two-and three-dimensional objects. Students work in a variety of lively real-world contexts, gathering measurement benchmarks in a classroom scavenger hunt and investigating the area of a rectangle while acting as owners of a sticker factory, for example. The supplemental CD-ROM features interactive electronic activities, master copies of activity pages for students and additional readings for teachers.
