                              Below is a pseudocode for moving a sprite with the arrow keys. Your task is to convert
                          this pseudocode into Scratch code using the appropriate Scratch blocks.
                          when green flag clicked
                          forever
                            if <key [up arrow v] pressed?> then
                            change y by (10)
                            end
                            if <key [down arrow v] pressed?> then
                            change y by (-10)
                            end
                            if <key [right arrow v] pressed?> then
                            change x by (10)
                            end
                            if <key [left arrow v] pressed?> then
                            change x by (-10)
                            end
                          end

                      People who are experts in Scratch may pursue their careers as Programmers.

                         FOR THE TEACHER
                        1.  Demonstrate all the blocks and their functions.

                        2.  Encourage the students to make different stories using Scratch.
