# Setting the Stage with Geometry

## Measuring Perimeter, Area, Surface Area, and Volume

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

The lessons below are accompanied by fun printable worksheets as well as extension worksheets and take-home activities. A Standards Chart for Common Core State and NCTM Standards is also available.

### Lesson Plans
