Students become familiar with the volume formulas for cylinders, cones, and spheres, and how they relate to previously explored volume formulas. They apply the formulas to find missing measurements and note how changing measurements influence the volume figure.

“Closure in a lesson does not mean to pack up and move on. Rather, it is a cognitive activity that helps students focus on what was learned and whether it made sense and had meaning.” How the Brain Learns Mathematics (2007) P. 104
There are many ways to wrap up and reflect the day's activities but this step is often overlooked or rushed. Purposely plan and allow time for students to have closure each day (even if it means setting a timer or daily alarm so you don't run out of time).
