Construction of 3D shapes
Teacher’s note : Cuboid, Cube, Cylinder, Sphere, Pyramid, Cone - Teacher can guide the children to draw 3D object and give the real object of the 3D shapes, so that the children can touch, feel and find out the answers.
Construction of 3D shapes.
Look at the things around you.
Identify the shapes of the objects. Observe the dimensions of these objects.

3D Shapes
Cuboid, Cube, Cylinder, Sphere, Pyramid, Cone
Solid shapes have 3 Dimensions namely length, breadth, and height.
These are shortly called as 3D shapes.
Let us know
A Cube is a solid shape made of squares. It has 6 faces, 12 edges and 8 vertices.
A Cuboid is a solid shape made of rectangles. It has 6 faces, 12 edges and 8 vertices.
A Sphere is a solid shape made of circles. It has 1 faces, no edges and no vertex.
Practice
