Task# Using Volume to Understand the Associative Property of Multiplication

Illustrative MathematicsVaries

The purpose of this task is for students to use the volume of a rectangular prism to understand the associative property of multiplication. Note that students do not need to use the term 'associative property' themselves, but they do need to understand that when you multiply three numbers, you can group them any way you want and still get the same result. Note that 5.MD.C.5 states that students need to apply the formula to find the volume of a right rectangular prism. In fact, an expression like only makes sense because multiplication is associative.
