    Computational Thinking is a problem solving method that is required to develop
                     coding skills. In this chapter, we will learn to develop Computational Thinking.

                               WORKING WITH SHAPES

                     You have often observed various objects. You might wonder as to what shape
                     they are made up of. Let us discuss about some of the basic shapes.

                     SQUARE

                       It has 4 sides.

                       All sides are equal.

                       It is made up of standing and sleeping lines.

                     RECTANGLE

                        It has 4 sides.
                        Only opposite sides are equal.

                        It is made up of standing and sleeping lines.

                     TRIANGLE

                        It has 3 sides.

                        The sides may or may not be equal.

                     CIRCLE

                        It is a round shaped figure.

                        It has 1 curved side.

                               RECOGNISING PATTERNS

                     When we draw or write the same thing again and again, we say that we have

                     made a pattern.

                     Look at the following examples of different types of patterns.

                     1.      2                  4                   6                  8                    10
