                    WHAT ARE BLOCKS?

                 Blocks are just like pieces of the jigsaw puzzle available in different shapes. They connect to
                 each other vertically to create code in Scratch. Each block type has its own shape and its own
                 slot shape for it to be inserted into. You simply drag these blocks into the coding area to create
                 a script. Series  of connected blocks  are called scripts. There are nine main  block categories
                 in Scratch 3.0. Let us discuss each of these categories one by one.
                 Motion Blocks

                 These blocks in Scratch are used to control the movement of the sprite. They help the user to
                 move or turn the sprite. There are 18 Motion blocks in Scratch 3.0.

                                                    Moves the sprite smoothly to the specified X and Y coordinates
                                                    in the given time.
