Learning Objectives

  1. Identify and define attributes of shapes
  2. Differentiate between regular and irregular shapes

Shapes of Objects

When we look around we find all objects having some shape or the other. A shape defines the structure of an object and it is one of the important attributes of an object. Match the following shapes that you see in nature.

What is a shape?

See the following image. It has sides and corners. It is made of lines and encloses some space. Given below is a list of common shapes that we use in our daily life.

Activity: Draw the shapes

Now, let us identify and draw some basic shapes. What shapes do we see in the things around us?

To draw any shape, connect the lines and dots. Dot or point appears as • and a line is represented as

Irregular shapes

Notice that in some of these shapes given above, the sides are unequal. Such figures are said to be irregular.

Activity: Making objects

In this activity, let us make commonly seen things and beings using regular and irregular shapes. Make your own animal motifs for making cards and gifts.

Activity: Partition shapes

Learn about how many sides are there in a shape. For each shape draw the line to make it half and colour one half of it red.

Learn: 2-Dimensional and 3-Dimensional

In this section, learn about dimensions and shapes associated with those dimensions. Three dimensional shapes include solid figures having a space inside them. The two dimensional figures are said to be planar.

Activities and Exercises

Make objects such as buses, flowers, animals using shape cut outs.

Find planar (2D) and solid (3D) things. Match with the shapes given below.
