    You have learnt about Scratch in the previous chapter. Scratch is a software which
                      helps you create many games. There are many versions of Scratch. The latest version
                      is Scratch 3.0.

                      You  know  that  Scratch  blocks  are  divided  into  different  categories.  Each  block

                      performs a different function. Let us recall some previous tasks and also learn about
                      these blocks in detail.

                      Block Categories

                      Blocks are the codes or commands used to create a program in Scratch. It looks like
                      a puzzle piece and each block connects with the other block to perform a task. The

                      blocks in Scratch are divided into different categories based on their functions. In
                      most of these blocks, you can change the value in the block to suit your script.

                      Motion Blocks

                      The blocks that are used to control the movement of a Sprite are known as Motion
                      blocks. They are in blue colour. Some of the commonly used motion blocks are:

                                         block lets the Sprite move forward (in the direction it is facing) the

                        number of steps given in the text box in the block. When we write the value with a

                        minus (–) sign, the Sprite moves backward, e.g., move – 10 steps                              .

                                             block lets the Sprite turn in a clockwise direction by the given

                        degrees and                         block turns the Sprite in an anti-clockwise direction

                        by the given degrees.

                          To make the Sprite jump to a new position on the stage, use                               block.

                        This block gives the x and y positions of the Sprite on the stage.

                          Use                       to tell the Sprite to follow one of the two given options: the

                        mouse-pointer or a random position.
