Blocks                                        Functions



                                                       This block  pauses  the  running of the  script  for the
                            wait  1 seconds
                                                       number of seconds.


                            If         then            This block executes a set of actions only if a specific
                                                       condition is true. It checks the condition and runs the
                                                       included blocks when the condition holds.



                            If         then            This block allows the program to perform one action
                                                       if a condition is true and another action if it is false. It

                            else                       checks the condition, executing the first set of blocks if
                                                       true, and a different set if false, providing a clear choice
                                                       between two paths.



                            repeat   10
                                                       This block repeats a set of blocks for a given number of
                                                       times.



                                                       This block  keeps  on repeating  a set  of blocks till  the
                            forever
                                                       stop button is clicked. It is similar to repeat block and
                                                       expands  automatically  to  accommodate  the  blocks

                                                       you snap inside it.

                            OPERATORS BLOCK


                  Scratch allows us to perform arithmetic and logical operations. It provides this feature
                  through Operators block. These blocks are light-green in colour.
