Why Lesson Planet?
Give small groups handfuls of unit cubes and then dare them to build as many rectangular prisms as possible using only 12 cubes. This engaging activity serves as an introduction to the volume of solid figures. In addition to volume, measurers also learn about surface area by counting the faces the cubes that are visible on their prisms. A neat printable data table comes with the lesson plan, along with a worksheet that reinforces newly acquired skills.
