# Lesson Plan: Surface Areas of Pyramids Mathematics • 6th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the lateral and total surface areas of pyramids using their formulas.

#### Objectives

Students will be able to

• understand that the total surface area of a pyramid is the sum of its lateral surface area and the area of its base,
• calculate the lateral surface area of a pyramid,
• calculate the total surface area of a pyramid,
• calculate a missing length of a pyramid when given its lateral surface area or total surface area.

#### Prerequisites

Students should already be familiar with

• the slant height and perpendicular height of a pyramid,
• the Pythagorean theorem,
• the definition of a right pyramid,
• the definition of a regular pyramid,
• interpreting nets of 3D shapes.

#### Exclusions

Students will not cover

• pyramids with bases that are not squares, rectangles, or triangles,
• oblique pyramids,
• the volume of a pyramid,
• cones,
• trigonometry.
