Lesson Plan: Surface Areas of Pyramids Mathematics • Second Year of Secondary School
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,
