Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

An excellent, in-depth resource would be an asset to your unit on writing an argument essay. It provides an explanation to each part of the essay as well as examples of transition words to strengthen your kids' writing. Additionally, the...

This heady calculus text covers the subjects of differential and integral calculus with rigorous detail, culminating in a chapter of physics and engineering applications. A particular emphasis on classic proof meshes with modern graphs,...

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

This exercise helps students understand how volume in figured, even when two or more parts of a prism are not overlapping. There is a teacher view, with a description of the activity and commentary, and a student view, with just the...

This site, which is provided for by Math World, is a lengthy site describing the various properties and mathematical explanations of the figures.

This page brings you to a table of contents of three-dimensional figures. Selecting a figure will bring you to a page defining and illustrating the figure with applicable formulas listed.

A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

[Free Registration/Login may be required to access all resource tools.] This study guide gives an overview of isometric view, orthographic view, cross-section, and nets.

This site describes the concept of oblique, expressing both triangles and three dimensional solids. Be sure to use the links to related terms, everyday examples, challenging problems, more information, and the interactive check point...

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

Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.

An informative resource on the nature of Platonic Solids and what constitutes these figures.

This site from ScienceWorld provides a short, informative description of many of the contributions of Pythagoras to mathematics. Links exist to some of the contributions as well as to additional information.

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...

Use this interactive tool to explore pyramids. Rotate the pyramid to view it from all sides. Increase the number of sides (even to well over 100) until it closely resembles a cone. The base can be made irregular and you can 'explode' the...
