- Subject: Math
- Driving Question: How do we identify 3D shapes?
- Pedagogical Method: Kinesthetic Learning
- Grade Level: 2, 3
- Duration: 70 minutes
- Delivery Method: Messenger Applications
Students will learn to distinguish between 2D and 3D shapes and their characteristics.
● Materials: laptops/tablets/Mobile phones/toothpicks and blue-tag + index card/paper/copybook
Also find attached the necessary resources in the Files section
- Find examples of 3D shapes in the environment.
- Describe the properties of 3D shapes using the keywords: faces, edges, and vertices.
- Explain how a 3D shape is composed.
Keywords: cube, sphere, cone, pyramid, cylinder, face, edge, corner, vertex
- Students should know 2D shapes and the differences/similarities between 2D and 3D shapes.
- Students should be able to create 2D shapes and some 3D shapes with paper or other materials.
Download the PowerPoints from Link 1 and Link 2, share them with the class, and share the title of the lesson and its objectives. Play Video 1 asking the students to stand up, clap, and use their bodies to model the shapes they see in the video.
After that, the students go on a scavenger hunt at home looking for 2D and 3D shapes. Have them show the items collected by taking pictures and sending them on the group. Have them type the names of the shapes collected.
Send voice messages to connect the examples the students shared to the shapes in the PowerPoints while also showing pictures of objects like a ball (sphere), Pepsi can (cylinder), a box (cube), etc. After that, ask them questions to make them think about how they can describe these shapes (prompting words: faces, edges, and vertices)
The cylinder has 2 flat faces, one curved surface, and no edges or corners.
The cube has 6 faces, 12 edges, and 8 vertices.
Using toothpicks and blue-tag, each student creates a 3D shape.
To check for understanding, have some students volunteer to send pictures of their 3D shapes. Others can volunteer to describe it by typing how many faces, edges, and vertices it has.
Project Link 3 and ask students to choose 1 to trace. Once traced, have each student cut out his/her net and fold it to form a 3D shape. Have them send pictures of their nets before and after folding them.
To check for understanding, have students do the formative assessment (Worksheet 1).
Go over the PowerPoints again emphasizing the name of each 3D shape and its properties.
For homework, have students visit Link 4 to review the lesson and practice using online sheets.
For a final assessment, use Test 1.
