This lesson utilizes the concepts of cross-sections of three-dimensional figures to demonstrate the derivation of two-dimensional shapes.

On this interactive website students practice various math skills including naming prisms and pyramids, drawing cross sections of prisms and pyramids, and exploring three-dimensional views.

During this activity, middle schoolers will create nets for prisms. They will find the volume and surface area of the shapes. They will also use interactive activities to review three-dimensional shapes.This lesson plan was created as a...

Geometry is the study of how to use math to describe and investigate different points, lines and shapes. The way that a shape is described in geometry is with a formula, which is simply a mathematical way to calculate different...

Learn about 2D shapes and temperature with King Toot.

In this lesson, 7th graders slice three dimensional objects to determine what two dimensional shape is created.

Can you judge an object by its shadow? Use your mental rotation skills to determine if a shadow can be produced by a particular shape.

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

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.]
