                     Warm Up                            Diwali Celebration

                   Diwali is a festival of lights. Houses, shops
                   and all other buildings are decorated with
                   lamps and rangoli. The scene depicts a
                   festive celebration in a traditional Indian
                   setting. But the decoration of the house
                   is incomplete. Observe the scene and do
                   as directed.

                   1.   Complete the wall pattern by colouring
                      the bricks.
                   2.  Colour the door using two colours such

                      that its top half looks the same as the
                      bottom half.
