In this lesson plan, students will learn about the defining features of a pyramid. They will then learn how to calculate various measurements of a pyramid using different formulas. They will end with a performance task where they will apply what they have learned to measure real-world pyramids.

## Lesson Objectives

After this lesson, students will be able to:

• Understand the formulas for measuring pyramids
• Calculate the surface area and volume of a pyramid

## Curriculum Standards

CCSS.Math.Content.7.G.B.6

Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

CCSS.Math.Content.7.G.A.1

Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

CCSS.Math.Content.7.G.A.2

Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
