Investigate the properties of three-dimensional figures with this Arctic-themed math lesson. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Bring the ocean floor to life! Earth science scholars discover the process of deep sea mapping in the third installment in a series of five lessons about ocean exploration. The teacher's guide includes helpful resources, worksheets, and...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Third graders describe 2D and 3D shapes. For this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have...

Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

In this formulas worksheet, students write the area, perimeter, and volume formulas of 17 2D and 3D polygons.  Students list properties of various types of triangles and the metric conversions for metric units.

In this three- and two- dimensional geometry learning exercise, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of...

Young scholars design their own playground equipment. In this design instructional activity, students take pictures of equipment they like and make a class pictograph of their favorite ones. They investigate the design, research...

What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Students define ellipses and their properties. In this calculus lesson, students analyze ellipses for their shape, center, major and minor axes. They create a paper ellipse to have a visual of what an ellipse really looks like in 3D.

Watch a video and complete the activities to learn about the properties of 3D shapes.

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.

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...

Work with this cube problem and see if you can find a pattern. Then you can check your solution with solutions already submitted.

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...

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.

The instructional tool explores various geometric solids and their properties. Student can manipulate and color the different shapes. Learners examine the edges, faces, and vertices of the different solid figures.

A comprehensive guide for learning all about square pyramids with definitions, properties, examples, and practice questions.

A comprehensive guide for learning all about spheres with definitions, properties, examples, and practice questions.

For this task, learners investigate the volume of tennis balls and their cylindrical container, the empty space around the balls, different ways of slicing them, and what their visualizations will look like. Aligns with G-GMD.B.4 and...
