Key Concepts

  • 3D Shapes
  • Faces of 3D Shapes
  • Identifying Shapes by their Faces

Learning Objectives

  • Students will be able to define what a 'face' is on a 3D shape.
  • Students will be able to identify the faces of cubes, rectangular prisms, cones, spheres, pyramids, and cylinders.
  • Students will be able to match a 3D shape to its corresponding face (square, rectangle, triangle, circle).

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they know what 3D shapes are. Briefly review some common 3D shapes like cubes, spheres, and cones. Explain that today, they'll be learning about the 'faces' of these shapes. Introduce the Kids Academy video 'Faces of 3D Shapes'.
  • Video Viewing (5 mins)
    Play the Kids Academy video 'Faces of 3D Shapes'. Instruct students to pay close attention to the shapes and their faces.
  • Discussion (5 mins)
    After watching the video, have a class discussion about the shapes and faces they saw. Ask questions to reinforce their understanding (see 'Discussion Questions').
  • Worksheet Activity (10 mins)
    Distribute a worksheet with pictures of different faces (square, rectangle, triangle, circle). Below each face, provide images of a cube, rectangular prism, cone, sphere, pyramid and cylinder. Students should circle the shape(s) that have the matching face.
  • Wrap-up (5 mins)
    Review the answers to the worksheet as a class. Reiterate the key concepts: faces are the flat parts of 3D shapes, and different shapes have different faces. Ask students to give real-world examples of objects that are shaped like the 3D shapes they learned about.

Interactive Exercises

  • Shape Sorting
    Provide students with physical models of cubes, rectangular prisms, cones, spheres, pyramids and cylinders. Have them sort the shapes into groups based on the shapes of their faces. For example, a group with shapes that have square faces, a group with shapes that have rectangular faces, etc.

Discussion Questions

  • What is a face on a 3D shape?
  • What shape has a square face?
  • What shape has a rectangular face?
  • What shape has a circular face?
  • Does a sphere have any faces? Why or why not?
