These blocks identify  what’s  happening  at  a  given  point  and  make your
                         Sensing      Sprites or background respond to user actions and different factors.

                                      These blocks let you make comparisons or perform arithmetic functions on
                        Operators     different values.

                                      These blocks are used to draw shapes and patterns on the stage, change the
                                      pen colour and size.

                   i +  SPRITE’S DIRECTION

                  You can change the direction of the Sprite by using the Turn block under the Motions block

                  menu. The                  block will turn  the  Sprite in a  clockwise  direction  by  the  specified

                  number of degrees. The                   block will turn the Sprite in an anti-clockwise direction
                  by the specified number of degrees.
                  The  value  of  the  degree  specified  in  the  Turn  block  can  be  changed  according  to  our
                  requirement.

                   i +  USE OF CONDITIONAL CONTROL BLOCKS

                  Many times, you have to do a task which is dependent on some condition. For example, you have
                  to make mango shake. There are two conditions:
                  a.   Go to the refrigerator and check if there are mangoes. If mangoes are there, then you will
                     make mango shake.

                  b.   If the mangoes are not there, you will make cold coffee.
                     Here the condition is the availability of mangoes.

                     We can also write this in two ways:
                     1.  if                                          2.  if

                             mangoes are available                           mangoes are available
                         then                                           then

                             make the mango shake                            make the mango shake
                                                                        else

                                                                             make cold coffee
