Key Concepts

  • Geometric Solids
  • Cones
  • Spheres

Learning Objectives

  • Students will be able to identify cones and spheres.
  • Students will be able to describe the characteristics of cones and spheres.
  • Students will be able to construct a paper cone (optional).

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about shapes. Introduce the terms 'geometric solid' and explain that these are 3D shapes. Show examples of everyday objects that are shaped like cones and spheres (e.g., ice cream cone, ball).
  • Cone Exploration (10 mins)
    Define what a cone is. Point out the circular base and the point at the top. Show different sized cones. (Optional) Demonstrate how to make a paper cone. If you choose to do the project, have materials ready.
  • Sphere Exploration (10 mins)
    Define what a sphere is. Explain that a sphere is round like a ball. Show different sized spheres. Compare and contrast cones and spheres.
  • Review and Activity (10 mins)
    Review the definitions of cones and spheres. Ask students to identify cones and spheres in the classroom or in pictures. You may also have them draw cones and spheres on paper.

Interactive Exercises

  • Shape Hunt
    Have students search the classroom for objects that are shaped like cones or spheres. They can draw pictures of what they find.
  • Paper Cone Craft
    Provide students with paper circles and guide them in creating their own paper cones. This reinforces the cone shape in a hands-on way.

Discussion Questions

  • What are some things in our classroom that look like a cone?
  • What are some things you play with that are spheres?
  • How is a cone different from a sphere?

Skills Developed

  • Shape identification
  • Observation
  • Fine motor skills (paper cone craft)

Educational Standards

CCSS.Math.Content.1.G.A.2:Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Students do not need to learn formal names such as "right rectangular prism.") CCSS.Math.Content.1.G.A.1:Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
