                 A computer cannot understand our language. It needs commands or instructions in a language it
                 understands. A computer programming language allows us to give instructions to the computer

                 in a language it understands. Scratch is an easy programming language that is used to create
                 games, animated stories and interactive arts and we can share these creations with one another
                 over the Internet. Scratch has blocks that are dragged to combine and create a project. In this
                 chapter we will learn about adding sprites, changing backdrops,  drawing shapes and using

                 different types of blocks. Before we actually start with all these, let us understand the screen of
                 the Scratch.
