Discovering 3D Shapes: A Grade 3 Adventure

Learning Objective

Identify and describe common 3D shapes such as cubes, spheres, cones, and cylinders.

What do you already know about 3D shapes?

What are 3D Shapes?

3D shapes are solid objects that have three dimensions: length, width, and height.

Cube

A cube has 6 square faces, 12 edges, and 8 vertices. All its faces are identical squares.

Sphere

A sphere is perfectly round and has no edges or vertices. It looks like a ball.

Cone

A cone has a circular base and a curved surface that tapers to a point called the apex.

Cylinder

A cylinder has two circular faces and a curved surface. It looks like a can or a drum.

Interactive Activity: 3D Shape Hunt

Provide students with a list of 3D shapes to find around the classroom or school. They can sketch and label the shapes they find.

Review and Recap

Recap the main characteristics of each 3D shape and ask students to share what they have learned.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
