Explore the world of solid shapes in this mini-lesson. Provides a definition, interactive examples, and interesting practice questions that help with understanding.

Learn about platonic solids, a special type of polyhedra. Read a definition, make three-dimensional models using printouts, and play with an interactive animation, which will show you the faces, vertices, and edges on platonic solids:...

A Platonic solid is a polyhedron made up of only one kind of regular polygon, that looks the same from every direction. (In other words, the same number of faces meet at every vertex.) There are only five different Platonic solids:...

[Free Registration/Login may be required to access all resource tools.] This study guide looks at the definitions and postulates of surface area and volume for different solids, including composite solids and similar solids.

Provides a list of area and perimeter formulas for two-dimensional shapes and volume and surface area formulas for three-dimensional solids.

Did you know that the five regular platonic solids (tetrahedron, octahedron, icosahedron, cube, and dodecahedron) were thought to represent earth, air, fire, water, and the universe? This chart shows an image and provides a description...

[Free Registration/Login may be required to access all resource tools.] This study guide reviews how to classify polyhedra, Euler's formula, and regular polyhedra.

This lesson focuses on polyhedra; a polyhedron (the plural is polyhedra) is a 3-dimensional solid object that is made up of polygons. Euler's Polyhedron Formula: In every polyhedron, the number of faces (F) plus the number of vertices...

Learn the mathematics behind modeling in three dimensions to maximize or minimize one aspect of the situation.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

[Free Registration/Login Required] In this lesson, students use the geometry program GeoGebra to explore Cavalieri's Principle, specifically to investigate whether it applies when calculating the volume of oblique solids. Lesson includes...

Introduces the concept of 3D shapes by learning the definition, types, properties, and three dimensions. Check-out the solved examples for better understanding and try your hand at solving a few interactive questions at the end of the page.

Describing 3D shapes in Pre-K and Kindergarten is now an expectation as it is a key geometry standard. This resource contains 3D shapes activities and resources for practicing this standard. Included are chants, videos, games, poetry,...

The students will find the area of each two dimensional figure on a net of a rectangular prism. In groups, students will cut out the net and create a rectangular prism. Groups will then discuss how to find the lateral area and the total...

Use this lesson plan to help students learn about cylinders. Students will be creating cylinders, and comparing them and their capacity. This engaging, hands-on lesson will hold student interest and be very beneficial to student learning.

This lesson offers an interesting, hands-on experience for middle school students studying cylinders. Students will create cylinders, and measure and compare their volumes.

[Free Registration/Login Required] In this lesson, students build geometric models of graduation caps using stiff paper. The activity requires the application of skills in finding surface area, understanding similarity, knowing the...

This site gives formulas for the area, volume, and surface area of various shapes.

Students explore surface area and volume through this lesson plan and worksheet activity.

This tutorial explains the concept of surface area, and then goes through multiple shapes offering the specific surface area formula for each one.

For this exploration, students will apply their knowledge of finding volume and surface area of cylinders and rectangular prisms. Students will make recommendations to the local movie theater after determining which package is cost...

In this lesson, students will estimate several dimensions of circles in everyday objects. Students will use the metric and customary systems for their estimations. This lesson plan was created by exemplary Alabama Math Teachers through...

In this lesson plan, young scholars will be required to generate a formula for volume of a rectangular prism. Students working in cooperative groups will use prior knowledge for finding area of a rectangle to determine the "amount of...

Use this calculator to determine the volume, surface area, or other figure for a square pyramid, given the other numbers. Users set their parameters for two known variables of the pyramid and find what the unknown amounts would be.
