Unit 6: Pythagorean Theorem, Angles & Volume

Overview

Ever wondered how to teach the Pythagorean Theorem, angles, and volume in an engaging way to your 8th-grade students?

In this unit plan, students will first learn about the Pythagorean Theorem. Later on, they will build on this to learn about finding the distance between two points using the distance formula in a coordinate system. Lastly, they will learn about solving problems involving the volumes of cylinders, cones, and spheres.

Each lesson helps students master the unit through artistic, interactive guided notes, check for understanding, and culminates with a real-life example that explores how these mathematical concepts are applied in real-world situations.

It's an exciting way to teach the Pythagorean Theorem, angles, and volume while comprehensively meeting standards.

Learning Objectives

After this unit, students will be able to:

  • Understand and apply the Pythagorean Theorem to find the missing side of a right triangle.

  • Calculate the distance between two points in a coordinate system using the distance formula.

  • Solve for missing angles in triangles using the Triangle Sum Theorem.

  • Apply the Exterior Angle Theorem to find missing angles in triangles.

  • Identify and solve angle relationships formed by parallel lines cut by a transversal.

  • Calculate the volumes of cylinders, cones, and spheres using the appropriate formulas.
