Finding the volume, or the amount of space, inside a rectangular prism can be as simple as counting the number of unit cubes it takes to fill the shape. But students don’t have to count the unit cubes one-by-one. They can also break apart the prisms layer-by-layer and count in groups of 4, for example. Another way to figure out the volume is through a formula: length × width × height.
This PowerPoint lesson is a multi-click animation sequence that introduces standards-based math skills and concepts. Also includes three practice pages at levels A (below grade level), B (at grade level), and C (above grade level), which may be distributed according to students' abilities!
