In this lesson, you will learn about three-dimensional shapes. Look at the pictures below.

  • Can you name the shapes of any of the pictures? Tell a parent or teacher what shapes you see below.

By the end of this lesson, you will know all about the different three-dimensional shapes!


Let's jump right in and start learning about three-dimensional shapes!

Three-dimensional shapes have three dimensions: length, width, and height. Three-dimensional shapes are not flat. You can hold a three-dimensional shape in your hand because it is solid.

The first shape you will learn about today is a cube. A cube is a three-dimensional shape. Can you count the number of squares on one of the cubes below? How many did you count? Tell an adult. If you counted six equal squares, you are correct! Each square is called a face. A cube has six faces. Try finding an object that is shaped like a cube in your learning space. Did you find a cube? Does it have six square faces? Fantastic!


The next three-dimensional shape you are going to learn about is a pyramid. Count the number of faces on the pyramid below. How many faces did you count? Tell an adult. If you said four faces, you are correct! A pyramid has three triangle faces and one square face.


A rectangular prism is a three-dimensional shape. How many faces are on a rectangular prism? Tell an adult. Did you answer six? Great! A rectangular prism has six faces. A rectangular prism is similar to a cube because they both have the same number of faces.

What do you notice is different about the rectangular prism? Tell an adult your answer. Did you say that some of the faces on the rectangular prism are longer than the faces on the cube? Excellent! A cube has six equal square faces. A rectangular prism has some faces that are rectangular.

The last three-dimensional shape you will learn about in this lesson is the triangular prism. How many faces does a triangular prism have? Tell an adult your answer. Did you say five faces? Great job! A triangular prism has bases that are triangles.
