A Program of The Actuarial Foundation. Aligned with Common Core State and NCTM Standards.

What is an actuary? An actuary is an expert in statistics who works with businesses, governments, and organizations to help them plan for the future. Actuarial science is the discipline that applies math and statistical methods to assess risk.

# Designing With Geometry

## Applying Key Geometry Concepts

Welcome to “Designing With Geometry,” a new math program designed to build understanding of key geometry concepts. Developed by The Actuarial Foundation with Scholastic, this program provides skill-building and critical-thinking activities in a real-world context.

LESSON PLANS

Lesson 1: Polygons on the Coordinate Plane
Using the coordinate plane, students will be able to draw polygons; measure length, perimeter, and area; find missing coordinates; and calculate distance.

Lesson 2: Scale Drawings of Geometric Figures

Students will be able to calculate a scale factor and use it to determine side lengths.

Lesson 3: Finding Missing Angle Measurements

Using knowledge of supplementary, complementary, adjacent, and vertical angles, students will be able to write and solve equations to find missing angle measurements.

Lesson 4: Congruence and Transformations

Students will be able to determine congruence as well as complete transformations, including translations, reflections, and rotations.

Lesson 5: Applying the Pythagorean Theorem

Students will identify the properties of a right triangle. Students will apply understanding of the Pythagorean Theorem to find distances on a coordinate grid or the lengths of the diagonals of rectangles.
