Lesson 6
Revisit Volume
Lesson Purpose
Lesson Narrative
In this lesson, students calculate the volume of different objects. The first activity recalls the meaning of volume as the number of cubic units required to fill a space. Students experiment with different ways to build a rectangular prism using a fixed number of cubes and relate this to finding factors of the number of cubes. In the second activity they estimate the volume of some very large structures, the great pyramid of Egypt and the Empire State Building. Neither shape is a rectangular prism though they are each made up of smaller shapes that are rectangular prisms. Students combine the skills of making reasonable estimates with finding products of very large numbers. If students need additional support with the concepts in this lesson, refer back to Unit 1, Section A in the curriculum materials.
