Name the three-dimensional shape
Key notes:
Introduction to Shapes: Start with basic shapes they already know like circles, squares, and triangles.
Three-Dimensional (3D) Shapes: Explain that 3D shapes are solid shapes that have depth (length, width, and height).
Common 3D Shapes: Introduce simple 3D shapes such as:
- Cube: A box-shaped object where all sides are equal squares.
- Sphere: A round ball shape.
- Cylinder: A shape with two circular ends and a curved surface.
Identifying 3D Shapes: Teach them how to recognize these shapes in everyday objects (e.g., a ball is a sphere, a dice is a cube).
Properties of 3D Shapes: Discuss basic properties like edges (where faces meet), vertices (corners), and faces (flat surfaces).
Hands-On Activities: Use hands-on activities like building shapes with clay or identifying objects in the classroom that resemble 3D shapes.
Learn with an example
✏️What shape is this?
- sphere
- cube
- cone
Look at all the faces of the shape.
There are 6 faces. They are all squares.
This shape is a cube.
✏️What shape is this?
- sphere
- cube
- cone
The shape has a pointy tip. This pointy tip is called a
vertex.
Look at all the faces of the shape.
The shape has one face. It is a circle. The rest of the shape is curved.
This shape is a cone.
✏️What shape is this?
- sphere
- cube
- cone
The shape is completely round. It has no flat surfaces.
This shape is a sphere.
