Practice finding the surface area of 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This site gives a description of edge along with a visual representation. Be sure to use the links to related terms, everyday examples, challenging problems, more information, and the interactive check point located in the left-hand column.

Using an engaging approach, this lesson requires students to record the volume of cylinders as a function of the radius. Students will construct and measure the volume of several cylinders and then begin comparing these shapes.

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

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,...

For this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...

A program that will randomly move an object from one location to another in three-dimensional space. You must determine the three components of the velocity vector that is created by this movement and also the speed of the object during...

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

A geometry lesson that examines the history and structure of ancient pyramids and engages students in constructing pyramid models. A comprehensive lesson that considers students with diverse learning styles. Math concepts introduced...

As a whole group, students will sort a collection of three-dimensional objects into categories by shape. There should be several that fall into each of the categories below: Aligns with 1.G.A.1.

This tutorial features templates and instructions to make the following solids: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.

In this task, students investigate the volume of tennis balls and their cylindrical container, the empty space around the balls, different ways of slicing them, and what their visualizations will look like. Aligns with G-GMD.B.4 and...

Print out these colorfully illustrated PDF file pages to practice learning your basic three dimensional geometric solids. Fold them in half and one side shows the shape while the other side shows the shape with the correct name. Put them...

Excellent interactive challenge working with cube nets to stack them in a specific order. Manipulate the cubes online to solve the problem.

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

Given an unlimited number of a specific type of equilateral, isosceles, and right triangles create as many tetrahedra as are possible. Includes printout.

In this enrichment game, the nets for nine solids are displayed. The twist is that each net has been cut into two pieces. The challenge is find the pieces that go together.

Twenty-four problems covering a variety of solid figure topics: dimensions, volume, surface and base areas. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click...

Improve your logic and net recognition skills with this learning game. Solution included.

Have fun and learn by making a box and then find out its maximum volume as well as other problem-solving activities, including making a table of your results and drawing a graph.

How many different cuboids can you make? Learn how and learn how to represent data with your results.

Predict which solid shape constructions would be unstable as shown at this one page website. Solutions are available right at the website.

An interactive game to find number of edges, surfaces and vertices of different geometric shapes.
