Practice identifying 3D shapes.

Practice your 3D visualization skills by rotating 2D shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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,...

Explore surface areas and nets with 2D and 3D shapes.

An introduction to a type of three-dimensional shape called a polyhedron. See examples and play with an interactive animation, showing the faces, vertices, and edges of pyramids, which are a type of polyhedron.

[Free Registration/Login may be required to access all resource tools.] Students watch a video overview on the flat surfaces or faces of 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.

See how the cross-sections of solids relate to their shapes.

My first graders have been studying the defining attributes of 2D shapes. They are going to love using toothpicks and marshmallows to present their knowledge of 2D and create 3D shapes.

[Free Registration/Login Required] Students will click on the point of the word and drag it to the correct figure. Click challenge me to answer practice questions and click learn more to watch a video.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to count the number of faces in various three dimensional shapes.

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.

Learn how to calculate the surface area and volume of rectangular prisms and cylinders. Four interactive animations, preceded by simple instructions, guide you through the process of calculating area and volume.

Test your knowledge of rectangular prisms and cubes.

Test your knowledge of determing the lengths and angles of right triangles.

Learn all about the basic properties of a cone. This lesson targets the formula, volume, parts, and shapes of a cone and has interesting solved examples and practice questions.

Can you help Leela find objects of different 3D shapes in her parents' tea store?

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

A geometry instructional activity that examines the history and structure of ancient pyramids and engages students in constructing pyramid models. A comprehensive instructional activity that considers students with diverse learning...

Cross-sections are one way that two-dimensional objects are connected to three-dimensional objects.
