Lesson Description
Video Resource
Faces of 3D Shapes - 3D Shapes For Children | Math for 2nd Grade | | Kids Academy
Kids Academy
Key Concepts
- 3D shapes have faces.
- A face is a flat surface on a 3D shape.
- Different 3D shapes have different numbers of faces.
- We can use imagination to count faces that are not immediately visible.
Learning Objectives
- Students will be able to define what a face is on a 3D shape.
- Students will be able to identify and count the faces of cubes, rectangular prisms, cylinders, cones, pyramids, and triangular prisms.
- Students will be able to use visualization skills to count hidden faces.
Educator Instructions
- Introduction (5 mins)
Begin by asking students what they know about shapes. Introduce the concept of 3D shapes and faces. Explain that a face is a flat part of the shape. - Video Viewing (7 mins)
Play the YouTube video 'Faces of 3D Shapes - 3D Shapes For Children | Math for 2nd Grade | | Kids Academy.' Encourage students to pay close attention to how the faces of each shape are counted. - Shape Exploration (10 mins)
Discuss each shape shown in the video: cube, rectangular prism, cylinder, cone, pyramid, and triangular prism. Ask students to describe the shapes and how many faces they have. Emphasize the importance of using imagination to count hidden faces. - Guided Practice (10 mins)
Draw 3D shapes on the board. Guide students through the process of counting the faces, step by step. For example, 'Let's look at this cube. It has a top face, a bottom face, a front face, a back face, a left face, and a right face. How many faces in total?' - Independent Practice (8 mins)
Provide students with worksheets containing pictures of 3D shapes. Ask them to count the faces of each shape independently and write the number next to each shape.
Interactive Exercises
- Shape Sorting
Provide students with a collection of 3D shapes (real objects or paper models). Ask them to sort the shapes based on the number of faces they have. For example, shapes with 6 faces in one group, shapes with 5 faces in another group, etc. - Face Hunt
Give students a picture of a complex figure made of different 3D shapes combined and ask them to hunt for the faces of each individual shape
Discussion Questions
- What is a face on a 3D shape?
- How is a face different from an edge or a vertex?
- Why is it important to use your imagination when counting faces on 3D shapes?
- Can you think of real-world objects that have the same shape as a cube, a cylinder, or a cone?
