[Free Registration/Login Required] In this lesson plan, young scholars will work with 3-Dimensional shapes identifying attributes of the shapes and recreating them. Students will create, identify and describe 3-Dimensional shapes as part...

In 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...

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.

Two and three-dimensional geometric shape are explored in these exercises. Each activity has teacher notes, activity instructions, and a worksheet when necessary.

Learn about platonic solids, a special type of polyhedra. Read a definition, make three-dimensional models using printouts, and play with an interactive animation, which will show you the faces, vertices, and edges on platonic solids:...

An architectural modeling lesson that first demonstrates how architects combine forms to create buildings and then provides instructions for building architectural models. Includes links to architectural terms and to useful illustrations...

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

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

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...

Download these worksheets to sharpen your geometry skills. Sheets focus on angles, coordinate geometry, triangles, quadrilaterals, transformations, and three-dimensional geometry, and more.

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

Use this lesson plan to help students learn about cylinders. Students will be creating cylinders, and comparing them and their capacity. This engaging, hands-on lesson will hold student interest and be very beneficial to student learning.

Students will tell if a shape is 2-dimensional or 3-dimensional.

Explore two and three dimensional geometric shapes by creating shapes based on descriptions.
