Breaking Apart Composite Solids

Illustrative MathematicsVaries

The purpose of this task is to help students see different ways of breaking a solid into right rectangular prisms and to relate volume to the operations of multiplication and division. This task combines the work that students have done in the Operations and Algebraic Thinking domain with their work on volume in the Measurement and Data domain. This task requires students to think backwards from two different given expressions to understand how different students might decompose the same irregular solid. There are a number of possible extensions to this task.
