                  Guess the components of Scratch.

                  1.  I am the main actor in the program.

                  2.  I can stop the program from running.


                  3.  I am the background where sprite is placed.




                 You have already learnt about Scratch and its components in previous class. Now you will learn
                 how to draw shapes in Scratch by writing scripts. To draw shapes in Scratch, you will use Pen

                 blocks. Let us learn about Pen blocks now.

                 PEN BLOCK


                 The Pen blocks are green in colour. These blocks draw a trail as the sprite moves on the stage.
                 You can change the colour of the pen. In Scratch 3, you have to add Pen blocks to the block
                 category. To do so, follow the given steps:                                                    2
