## Reflection: Adjustments to Practice Explore Volume of Rectangular Prisms - Section 3: Independent Problem Solving

This ends up being a pretty easy objective for students to master.  It becomes kind of silly to ask them over and over again to multiply three numbers to find the volume.  I ended up adding, on the fly, a few more volume problems where students had to find an unknown dimension given the volume and two other dimensions.  May some problems using algebraic expressions would be a good side.

Example:

The volume of a rectangular prism is 240 cubic units.  The length is x -5 units, the width is 12 units and the height is 3 units.  What is the length of the prism?

This would help this "additional" standard help support the "major cluster" - expressions and equations.
