Check out this math project about polyhedra! Young scholars will enjoy the hands-on activity while they learn about tetrahedrons, hexahedrons, octahedrons, dodecahedrons, and icosahedrons. [Requires Adobe Reader.]

A geometry instructional activity that examines the history and structure of ancient pyramids and engages students in constructing pyramid models. A comprehensive instructional activity that considers students with diverse learning...

Use this interactive tool to explore prisms. Change the height and the shape of the base to see how these affect the prism. There are also several additional options, e.g., making it oblique or transparent. Properties of a prism are...

The resource consists of a tool to investigate the area of a variety of shapes. It could also be useful when calculating the surface area of each face of a 3D solid, and then adding them together.

This site includes an interactive math tool to create drawings on isometric dot paper. You can draw figures using edges, faces, or cubes. Rotate and color your drawings, and view them in 3D or 2D.

Use this tool to see animated models of over 100 different types of polyhedra. There are five options for how they appear, and you can also see the net, 'explode' the solid so that the faces are separated, or drag it to rotate it...

Practice matching 2D nets to the 3D shapes the fold up into. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve word problems involving volume and surface area involving 3D shapes, including composite figures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Provides an explanation, examples, and video lessons all related to area and volume of pyramids, prisms, cylinders, and cones.

Brush up on your math skills relating to cross-sections then try some practice problems to test your understanding.

This interactive exercise focuses on discovering the relationships between two and three-dimensional shapes.

[Free Registration/Login Required] This is a formative assessment task where students are asked to use geometric solids to model each of four tent shapes on a worksheet and use mathematical language to describe them. Samples of student...

This site provides an in-depth definition of a two-dimensional figure and a three-dimensional figure. Related terms include arcs, vertices, polygon, and many more.

Practice your knowledge of all possible cross-sections of common 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Work with this cube problem and see if you can find a pattern. Then you can check your solution with solutions already submitted.

Use Glencoe's randomly generated self-checking quiz to test your knowledge of three-dimensional figures. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check It"...

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

Determine the expression that finds surface area of a 3D shape by adding the area of each face. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Estimate the volume you get when you fill 3D shapes with candy. This video focuses on estimating volume using nonstandard units, using the volume equation to get a more reliable estimate and checking your estimate by counting the...
