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

1. Complete the following table by filing the properties of 2d and 3d shapes.

2. Match the following.

Teacher’s note : Teacher shall facilitate the children to draw the front and side views of 3d shapes by providing the objects.

Activity 4

Join the dots to form 3D shapes.

Activity 5

Complete solid shapes and colour it.

Sphere, Cuboid, Cube, Cone, Cylinder, Cube

Teacher’s note : 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.
