Setting the Stage with Geometry

Measuring Perimeter, Area, Surface Area, and Volume

Welcome to Setting the Stage with Geometry, a new math program designed to help students build basic skills for measuring 2D and 3D shapes. Developed by The Actuarial Foundation with Scholastic, this program seeks to provide activities to help students become successful in the classroom and in real-world situations outside of school.

Each of the three lessons below is accompanied by fun printable worksheets as well as extension worksheets and take-home activities.
