    In the previous class, we  have  learned  about  a  block-based  visual  programming
                      language that is Scratch. It is used to create interactive stories, animations, games,
                      etc. Let us recall some previously done activities and learn more about them.

                      Coding Blocks

                      Coding blocks in Scratch are puzzle-piece shapes that are used to create codes.

                      There are six types of block shapes in Scratch, and each of them helps the user define
                      steps of animation related to the selected blocks. It also provides an interface to
                      input the value of movement or look of a Sprite in a project.
