High schoolers identify the volume of cones and pyramids. In this geometry activity, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.

Students sketch cones and identify its properties. In this geometry lesson, students calculate the surface area and volume of each three dimensional shape. they define and sketch prisms, pyramids and cylinders.

Unlike a volcano, the lesson won't blow up in your face. Young mathematicians use dried beans to discover the relationship between the volumes of cones and cylinders and to write a formula for the volume of a cone. They then research...
