    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
