• Lesson Plan
• Subject: Math
• Driving Question: How do we make connections between 2D and 3D shapes?
• Pedagogical Method: Kinesthetic Learning
• Duration: 45 minutes
• Delivery Method: Messenger Applications
• ### Purpose

Students will learn to make connections between 2D and 3D shapes and identify 3D shapes that are formed from 2D shapes.

• ### Before you start

● Materials: laptops/tablets/Mobile phones
Also find attached the necessary resources in the Files section

• ### Objectives

• Recognize that 3D shapes are formed of 2D shapes.
• Identify the 2D shapes that form the following 3D shapes: cube, pyramid, rectangular prism, cylinder, and cone.

Keywords: circle, rectangle, square, triangle, cylinder, cone, pyramid, cube, sphere, rectangular prism

• ### Prior Knowledge

• Students know that 2D shapes are 2-dimensional (length, width) whereas 3D shapes have length, width, and height.
• Students can name basic 2D and 3D shapes.

• ### Warming Up (10 minutes)

After greeting, taking attendance, and checking up on students, begin the lesson by sending a link to a song (Video 1) to help students remember 2D shapes. Students are encouraged to move their bodies and hands to form the different shapes they are viewing in the video.

• ### Learning Activity 1 (15 minutes)

Ask students to go on a scavenger hunt and find one 3D shape they can use for this activity. This 3D shape should be cheap and the students should be able to break it apart. Have students send pictures of the items collected.

Send a video showing a tissue box. Think aloud saying, “This is a cube. I wonder how this cube was formed?” Then, break down the tissue box unfolding and revealing its parts. Ask, “What makes up a cube?” and share that 6 squares make a cube. Then, have each student break up the 3D shape he/she has and observe what parts it is made up of. Volunteers can share by taking pictures of their objects before and after breaking them down.

To check for understanding, share each slide of PowerPoint 1 one at a time and ask volunteers to type or send a voice message describing what 2D shapes they see and what they think they are faces of.

• ### Learning Activity 2 (15 minutes)

Ask students to watch the Video 2 to get a better understanding of the concept.

Have each student use any materials available to construct a 3D shape (playdough, papers, cardboards, pencils…). Students can take and share pictures/videos of their constructions explaining what 2D shapes they used to create their 3D shapes.

To check for understanding, send students Link 1.

• ### Wrap-Up (5 minutes)

Instruct students to send one smiley face if the statement is true and a sad face if it is false. Wait a minute after sending each sentence and then follows it with the answer.

1- A cube is made of 6 squares.

2- A cone has 1 curved surface and a circle.

3- 6 squares make a rectangular prism.

4- A pyramid has 1 square and 4 triangles.

For homework, send students Link 2.

For a final assessment, send students Link 3.
