Round out a lesson on spheres by using different media. Scholars view a video to learn how to find the surface area of a sphere by substituting into the formula. They then use a worksheet to practice the skill.

Quick, name that shape! Scholars learn the names and common properties of three-dimensional solids. They watch a short video that shows an example of each shape and identifies the two-dimensional faces that make up its surfaces.

The formula for the volume of a sphere is volume equals four-thirds pi times the radius cubed. That's a mouth-full. But if you are given the radius value of the sphere, all you have to do is plug it in and do the arithmetic. Just...

What do a basketball, a bowling ball, and a ping pong ball all have in common? They are spheres. So how do you measure the surface area of a sphere? Yes, there is a formula and all you have to do is know one measurement of the sphere to...

This video shows a demonstration of symmetry by folding and cutting spheres.
