Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

A set of first grade geology lessons focuses on plate tectonics and movement of plate boundaries. During the pre-lab, learners experience three types of plate movement through a kinesthetic demonstration. The lab...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

Explore the world of solid shapes in this mini-lesson. Provides a definition, interactive examples, and interesting practice questions that help with understanding.

Introduces the concept of 3D shapes by learning the definition, types, properties, and three dimensions. Check-out the solved examples for better understanding and try your hand at solving a few interactive questions at the end of the page.

Meet Morisu in the dojo. Help him with symmetrical objects and shapes!

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on identifying faces, edges and vertices of three dimensional shapes.

Students will create a model of a three-dimensional shape and create tessellations on a computer using two-dimensional shapes.

A complete reference guide to solid geometry. The mathematics resource provides definitions and interactive activities that enhance further explanation.

This tutorial features templates and instructions to make the following solids: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.

[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.

[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.

[Free Registration/Login may be required to access all resource tools.] The video shows how to count the number of flat surfaces on various 3D shapes. The video is followed by practice problems.

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.

Join Allegro in his street orchestra and learn about 3D shapes.

Discover the characteristics of 3D shapes in this fantasy world of fish.

Discover 2D shapes and 3D objects from different views in Antarctica!

Describes the basic three-dimensional figures students will encounter in elementary Math and in the world around them, and makes mention of a few unusual ones.

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