Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Cakes offer a yummy way to learn about math. Scholars use manipulatives to discover the formulas for the surface area and volume of prisms and cylinders. They use their formulas to calculate the amount of cake mix and frosting necessary...

This site provides an online rectangular prism calculator. Using any three of the six attributes (length, width, height, surface area, volume or diagonal), students can calculate the other three attributes. The calculator allows students...

Use prior knowledge of a rectangular prism to determine the formula of a cylinder. Check for understanding with the assessment at then end of lesson.
