At its foundation, a cone usually has a circular base. From there, a single face rises to a point at the top called the apex, or vertex. There are different types of cones, which include right circular, convex, double, and many others. The games, worksheets, and activity ideas from Education.com below will help your students explore the different types of cones and their properties.

Conical objects can be found in numerous areas of everyday life. Though many students instantly think of a bright orange traffic cone, there are more sophisticated examples of cones.
Beyond the basics, students can also expect to use their understanding of cones in as they advance in their educational and professional lives. Careers such as optometry, for example, rely on a deep understanding of cones to understand how the eye’s retina functions.
To better understand cones and how they work, students will need to become comfortable with measuring volume
, as well as other characteristics such as surface area. Two critical formulas will help students as they work with these properties. Calculating both surface area and volume are important skills students should work on:
- Surface area: πr(r+√h2+r2)
- Volume: 1⁄3r2h
These formulas require an understanding of π (pi), as well as radius, height, and more. As students use the games and activity ideas provided by Education.com above, they will build competency in a number of mathematical skills.
From understanding how to use exponents to working with interdependent properties such as volume and surface area, studying conical objects provides students with great opportunities to build their math skills.
