STC Program: Comparing and Measuring, 2nd Edition
Comparing and Measuring focuses on activities that young children enjoy: finding out who's taller, what's longer, and what's farther. Explorations provide a groundwork for understanding that measuring is based on comparing and the use of standard units enables people to work with and communicate size comparisons effectively. The activities move students in steps from the concrete toward the more representational.
