2D and 3D Shapes and Connections

Lesson Plan
 Subject: Math
 Driving Question: How do we make connections between 2D and 3D shapes?
 Pedagogical Method: Kinesthetic Learning
 Grade Level: 1, 2
 Duration: 45 minutes
 Delivery Method: Synchronous

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

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

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

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.

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 show the objects collected on the cameras.
Model showing a tissue box. Think aloud saying, “This is a cube. I wonder how this cube was formed?” Then, ask the students to use their bodies to gesture how a cube might be formed.
Ask, “What makes up a cube?” and share that 6 squares make a cube. Have each student break up the 3D shape he/she has and observes what parts it is made up of. Volunteers can share by showing the different faces on the screen and describing them.
To check for understanding, share each slide of PowerPoint 1 one at a time and ask volunteers to take turns describing what 2D shapes they see and what they think they are faces of.

Play 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…). In breakout rooms, students will share their constructions with their group members explaining what 2D shapes they used to create their 3D shapes.
To check for understanding, send students Link 1.

Instruct students to jump once if the statement is true and twice if it is false:
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.
