A lesson in creating 3-D solids using toothpicks and marshmallows.

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

These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

[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...

In this lesson, students will create a shape mobile of 2-dimensional and 3-dimensional shapes made from geometric shapes.

Learn about several three-dimensional geometric shapes and the terminology used to describe them. Learn how to calculate their surface area and volume, and explore their mathematical properties.

Resource examines the area of geometric solids through examples and a video lesson. [0:39]

You will have to use visualization to help you solve this challenge. At this one page website, you will be able to check your solution.

If you can visualize a cube and turn it around in your mind, then this is the challenge for you. This one page website has the solution available to check your thinking.

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

"The volume of a cube can be developed by considering unit cubes, a single row (longs) of unit cubes or a single layer (flats) of cubes using this applet." This easy software makes it possible to easily construct a cube and take it...

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.]

This Math Forum instructional activity gives instructions on how to build a paper pyramid. Bonuses included finding the surface area and volume of the pyramid.

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.

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

Name various 3D shapes in this online game.

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.

Identify the parts of 3D shapes in this assessment.

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.
